Gene-edited stem cells help geckos regrow more perfect tails

Regenerating body parts is never easy. For instance, some lizards can grow back their tails, but these new appendages are pale imitations of the original. Now, genetically modified stem cells are helping geckos grow back better tails.

Tweaking and implanting embryonic stem cells on the tail stumps of mourning geckos (Lepidodactylus lugubris) allowed the reptiles to grow tails that are more like the original than ever before, researchers report October 14 in Nature Communications. These findings are a stepping-stone to developing regenerative therapies in humans that may one day treat hard-to-heal wounds.

A gecko’s tail is an extension of its spine — with the vertebrae to prove it. Regenerated tails, however, are simpler affairs. “It’s just a bunch of concentric tubes of fat, muscle and skin,” says Thomas Lozito, a biologist at the University of Southern California in Los Angeles.

That’s because stem cells in adult geckos produce a molecular signal that encourages the formation of cartilage in new tails, but not bone or nervous tissues (SN: 8/17/18). Lozito and his colleagues used embryonic stem cells, which can develop into a wider range of tissues than adult stem cells, modified them to ignore this signal and then implanted them on the tail stumps of geckos that had their tails surgically removed. The tails that grew from these modified stem cells had bonelike grooves in the cartilage and generated new neural tissue at the top of the tail.

These modified tails still lack a spinal cord, making them a far cry from the original. “We fixed one problem, but there are still many imperfections,” Lozito says. “We’re still on the hunt for the perfect tail.”

A supernova’s delayed reappearance could pin down how fast the universe expands

A meandering trek taken by light from a remote supernova in the constellation Cetus may help researchers pin down how fast the universe expands — in another couple of decades.

About 10 billion years ago, a star exploded in a far-off galaxy named MRG-M0138. Some of the light from that explosion later encountered a gravitational lens, a cluster of galaxies whose gravity bent the light so that we see multiple images. In 2016, the supernova appeared in Earth’s sky as three distinct points of light, each marking three different paths the light took to get here.

Now, researchers predict that the supernova will appear again in the late 2030s. The time delay — the longest ever seen from a gravitationally lensed supernova — could provide a more precise estimate for the distance to the supernova’s host galaxy, the team reports September 13 in Nature Astronomy. And that, in turn, may let astronomers refine estimates of the Hubble constant, the parameter that describes how fast the universe expands.

The original three points of light appeared in images from the Hubble Space Telescope. “It was purely an accident,” says astronomer Steve Rodney of the University of South Carolina in Columbia. Three years later, when Hubble reobserved the galaxy, astronomer Gabriel Brammer at the University of Copenhagen discovered that all three points of light had vanished, indicating a supernova.
By calculating how the intervening cluster’s gravity alters the path the supernova’s light rays take, Rodney and his colleagues predict that the supernova will appear again in 2037, give or take a couple of years. Around that time, Hubble may burn up in the atmosphere, so Rodney’s team dubs the supernova “SN Requiem.”

“It’s a requiem for a dying star and a sort of elegy to the Hubble Space Telescope itself,” Rodney says. A fifth point of light, too faint to be seen, may also arrive around 2042, the team calculates.、
The predicted 21-year time delay — from 2016 to 2037 — is a record for a supernova. In contrast, the first gravitational lens ever found — twin images of a quasar spotted in 1979 — has a time delay of only 1.1 years (SN: 11/10/1979).

Not everyone agrees with Rodney’s forecast. “It is very difficult to predict what the time delay will be,” says Rudolph Schild, an astrophysicist at the Harvard-Smithsonian Center for Astrophysics in Cambridge, Mass., who was the first to measure the double quasar’s time delay. The distribution of dark matter in the galaxy hosting the supernova and the cluster splitting the supernova’s light is so uncertain, Schild says, that the next image of SN Requiem could come outside the years Rodney’s team has specified.

In any case, when the supernova image does appear, “that would be a phenomenally precise measurement” of the time delay, says Patrick Kelly, an astronomer at the University of Minnesota in Minneapolis who was not involved with the new work. That’s because the uncertainty in the time delay will be tiny compared with the tremendous length of the time delay itself.

That delay, coupled with an accurate description of how light rays weave through the galaxy cluster, could affect the debate over the Hubble constant. Numerically, the Hubble constant is the speed a distant galaxy recedes from us divided by the distance to that galaxy. For a given galaxy with a known speed, a larger estimated distance therefore leads to a lower number for the Hubble constant.

This number was once in dispute by a factor of two. Today the range is much tighter, from 67 to 73 kilometers per second per megaparsec. But that spread still leaves the universe’s age uncertain. The frequently quoted age of 13.8 billion years corresponds to a Hubble constant of 67.4. But if the Hubble constant is higher, then the universe could be about a billion years younger.

The longer it takes for SN Requiem to reappear, the farther from Earth the host galaxy is — which means a lower Hubble constant and an older universe. So if the debate over the Hubble constant persists into the 2030s, the exact date the supernova springs back to life could help resolve the dispute and nail down a fundamental cosmological parameter.

UEFA Champions League draw: Date, teams qualified, seeds, rules for Round of 16

The complete field of 16 teams that will advance to the 2021-22 UEFA Champions League knockout rounds has not yet been finalized, but we already have several clubs that have booked their spots.

European giants Liverpool, Ajax, Bayern Munich and Juventus were the first four teams to clinch on Matchday 4 of the group stage, while Manchester United and Chelsea joined them on Matchday 5.
Only the top two teams in each group advance, and there's incentive to win the group when it comes to the Round of 16 draw on Monday, Dec. 13. The first-place team from each group will be seeded, and their Round of 16 opponent will be drawn from a pot of the second-place finishers.

When is the Champions League Round of 16 draw?
The Round of 16 draw will be held on Dec. 13 at 6 a.m. ET from the UEFA headquarters in Switzerland. It will be streamed by UEFA.com.

The eight group winners will be seeded for purposes of the draw. They will make up one pot, while the other pot will contain the runners-up from each group.

The two key details to remember for this Round of 16 draw:

Teams from the same country cannot be drawn against one another (see table below);
The group winners (i.e. seeded teams) will host the second leg of each Round of 16 series. This is perceived to be an advantage because, if an extra-time session or penalty-kick shootout is needed, it would happen on home soil.
Knockout round qualifiers by country
Nation Total Clubs Clubs
England 3 Chelsea, Liverpool, Manchester United
Germany 1 Bayern Munich
Italy 1 Juventus
Netherlands 1 Ajax Amsterdam
The two legs of the Round of 16 will be spread over eight days between February and March. The second leg of each series will take place three weeks after the first leg.

The eight teams left standing will participate in a quarterfinal draw on March 18, 2022, which will determine the rest of the Champions League bracket through the final in Saint Petersburg on May 28. There are no seedings involved in this draw, and unlike the Round of 16, teams from the same country can be drawn against one another.

UEFA Champions League 2021-2022: Tournament format
The 2021-2022 edition of the UEFA Champions League features a familiar format — and one massive new twist.

As usual, the tournament started out with a group stage (eight groups of four teams each), and only the top two finishers in each group advance to the Round of 16 that kicks off in February 2022. Two-leg, aggregate-goal knockout rounds are played the rest of the way through to the single game final that will be held in Russia on May 28, 2022.

Group Stage: Sept. 14-15, Sept. 28-29, Oct. 19-20, Nov. 2-3, Nov. 23-24, Dec. 7-8
Round of 16: Feb. 15-16, March 8-9 / Feb. 22-23, March 15-16
Quarterfinals: April 5-6, April 12-13
Semifinals: April 26-27, May 3-4
Final: May 28, 2022 (St. Petersburg, Russia)
No away goals tiebreaker in Champions League
Here's that twist: For the first time since 1965, there will be no away goals tiebreaker used in the knockout rounds of UEFA competitions, including the Champions League, after it was abolished in June 2021.

Series that are tied on aggregate goals after the conclusion of the second leg will go straight to extra time and, if necessary, a penalty-kick shootout.

How to watch the UEFA Champions League
The 2021-22 UEFA Champions League will be carried in the United States by CBS (English) and Univision (Spanish) across a number of TV and streaming platforms.

Terence Crawford vs. Shawn Porter PPV price: How much does it cost to watch 2021 fight on ESPN?

There will be much more on the line Saturday night than just the WBO welterweight title.

If Terence Crawford can defeat Shawn Porter to move to 38-0, he could set himself up for even bigger battles down the road. Even Crawford himself has acknowledged that he has more blockbuster bouts on his mind, including a potential clash with Errol Spence Jr.
"I've been calling for these fights," Crawford told Timothy Bradley Jr. "Me and Shawn, we talked about fighting. I've told him, 'I'm not looking to fight you.' I'm looking to fight Spence. I'm looking to fight Keith Thurman because, you know, they got something to offer. I'm looking at them trying to use Shawn as a pawn because they know Shawn, he's gonna fight anybody.

"If I do too good, they might back up even more. We're here now. I'm gonna show them why they've been ducking me."

Can Crawford continue his run of dominance and put a notable win on his resume? Or will Porter pull off the upset in Las Vegas?
Boxing fans can purchase the Crawford vs. Porter pay-per-view through ESPN+. The prelim card will air live on ESPN2 starting at 7 p.m. ET.

What time is Terence Crawford vs. Shawn Porter?
Date: Saturday, Nov. 20
Time: 9 p.m. ET | 6 p.m. PT
Main event: 11:30 p.m. ET | 8:30 p.m. PT (estimate)
The Crawford vs. Porter fight card is scheduled to start at 9 p.m. ET on Saturday, Nov. 20. Crawford and Porter are expected to make their ring walks around 11:30 p.m. ET, though that could change depending on the length of the earlier fights.

Nikola Jokic injury update: Nuggets star out vs. Bulls with right wrist sprain

The Denver Nuggets will be without their superstar and the league's reigning MVP Nikola Jokic when they take on the Bulls at home.

This is the first game that Jokic will miss this season due to an injury, with the only other game he didn't suit up for so far was due to a suspension, following his altercation with the Miami Heat's Markieff Morris.
Through 14 games, he's averaging career-highs of 26.4 points and 13.6 rebounds while also dishing out 6.4 assists on career-high shooting efficiencies of 59.3 percent from the field and 41.0 percent from beyond the arc.
What's next for Jokic? Here's everything we know about his injury.

What is Nikola Jokic's injury?
Hours before the game against the Bulls, the Nuggets declared Jokic out with a right wrist sprain.
It's an injury that the Serbian big man reportedly suffered midway through the team's previous game, a home loss against the Philadelphia 76ers. Although he played until the end, he was seen favouring it in the second half.

How long is Nikola Jokic out?
It's currently unknown if Jokic will miss more than one game. In addition, the Nuggets will be without other key young stars in Jamal Murray (ACL) and Michael Porter Jr. (back).

The Serbian has been one of the most reliable players in his career, having missed just 20 games through his six previous seasons.

Nuggets upcoming schedule
The Nuggets enter this Bulls game with a 9-6 record, good for sixth in the West prior to Friday's games.

After this Bulls game, Denver will kick-off a road-heavy schedule as they play nine of their next 10 games away from home.

Date Opponent Time (ET)
Nov. 21 at Suns 8:00 p.m.
Nov. 23 at Trail Blazers 10:00 p.m
Nov. 26 vs. Bucks 9:00 p.m
Nov. 29 at Heat 7:30 p.m
Dec. 1 at Magic 7:00 p.m
Currently, the Nuggets rank third in defensive rating (103.8) and 20th in offensive rating (106.2).

ESPN's Stephen A. Smith goes off on Nets after loss to Warriors, says Kyrie Irving 'betrayed' Kevin Durant

Stephen A. Smith was in attendance for Tuesday night's game between the Nets and Warriors. He didn't like what he saw from Brooklyn — and that's putting it mildly.

The ESPN analyst unloaded on the Nets during Wednesday's edition of "First Take" after watching the Warriors hand them a 117-99 loss at the Barclays Center. Golden State led by 22 points at the end of the third quarter, prompting Brooklyn coach Steve Nash to wave the white flag and pull Kevin Durant and James Harden out of the game. Warriors star Stephen Curry continued what has been an electric start, scoring a game-high 37 points on 12-of-19 shooting and earning MVP chants in the Nets' home arena.
Smith declared that Durant is "all alone" in Brooklyn and "made the wrong decision" by joining the franchise in 2019. He also unloaded on Harden for his poor play, ripped Kyrie Irving for his "betrayal" of Durant and called out Nets fans for their lack of spirit.

It was… a lot. His full comments:
The Nets are 10-5 overall, putting them behind only the Wizards (10-3) and Bulls (10-4) in the Eastern Conference standings. They have won eight of their last 10 games, and they have not gotten a single minute from Irving, who will continue to stay away from the team until he is compliant with local health and safety protocols. Smith paints an ugly picture, but things could be much worse.

Still, even Nash admits that the Nets don't belong in the top tier of NBA teams.

"I just don't think we're in that category yet," Nash told reporters Tuesday. "We got a lot of work to do."

It feels safe to say that Smith agrees with Nash's assessment.

You can watch the full segment from "First Take" below.

Why did the Suns draft Deandre Ayton instead of Luka Doncic?

Leading up to the 2018 NBA Draft, Luka Doncic dominated the discussion.

A standout in Europe for years as a kid playing against men, Doncic seemed to be a surefire future NBA star.
Debuting for Real Madrid as a 15-year-old, it took all of two seasons as a professional before he led the team to the EuroLeague title, claiming EuroLeague MVP honors in the process.

Four years on, Doncic is a legitimate MVP candidate, with many wondering how and why he slipped through the Suns' fingers.
Predraft
Despite flashing the obvious talent of a potential No. 1 overall pick, ESPN's Jonathan Givony highlighted some of the potential challenges that International prospects face.

"With as small as the world has become, and even though we have more film and information at our fingertips than ever, I still believe that international players are at a disadvantage in the NBA draft process compared with their NCAA peers," Givony wrote.

"There is simply a comfort level and a familiarity for NBA teams in scouting college players that internationals don't enjoy. Most NBA execs will get over to Europe once or twice, and what if you happen to fall on one or two bad games?"

Of course, America has produced endless top picks that have failed to reach expectations, but perhaps the international prospects are more memorable. Andrea Bargnani comes to mind, the No. 1 overall pick from the 2006 Draft. Or even Ricky Rubio, who similarly to Doncic, had carved out an impressive resume as a teenager in Europe. Now in season 11 in the NBA after being taken with the No. 5 pick in the 2009 NBA Draft, Rubio has had a successful pro career without doubt, but he hasn't reached the All-Star level that many once hoped he would.

Prior to the Draft, there were some question marks whether or not Doncic would want to play for Sacramento, Atlanta or Memphis, who held the selections immediately after Phoenix. Of course, Doncic would have the option to continue playing in Europe after Draft night and not make his way to the NBA.
Draft night
With Phoenix firming on selecting Deandre Ayton with the first overall pick and Doncic reportedly distancing himself from Atlanta, the Hawks began conversations with the Mavericks.

What followed was a blockbuster trade that saw Doncic end up in Dallas, with Trae Young heading to Atlanta.

Of course, Ayton would go No. 1, with Marvin Bagley II heading to Sacramento with pick No. 2 and Jaren Jackson Jr. heading to Memphis with pick No. 4.

"[Dallas] been talking to me," Doncic told the ESPN/ABC broadcast on Draft night. "They were so nice to me. And I'm glad, you know? Just happy to be in the NBA. Just happy to be a part of that."

Adding to the intrigue was the presence of Phoenix head coach Igor Kokoskov, who had close knowledge on Doncic's talents as the head coach of the Slovenian national team. Kokoskov was fired in April of Ayton's rookie season. After returning to Europe for a stint, he is now on the staff in Dallas…once again working with Doncic.

Why did Phoenix select Ayton?
While the obvious guard comparison between Doncic and Young will be equally evergreen, the biggest question that remains is why the Suns chose a center in an era where the traditional big man's importance has seemingly waned?

Givony was on the money with his pre-lottery analysis, reporting that Ayton was firming as the likely top selection.

"After canvassing most of the league in recent weeks, there seems to be somewhat of a consensus forming around Ayton as the 'safe pick' at No. 1," Givony wrote.

"Which team ends up getting the pick will obviously play a role, but Ayton's sheer productivity combined with his freakish physical tools are making it increasingly difficult to keep Luka Doncic up top, especially after a somewhat lackluster month of February by his standards."

It's no knock on Ayton, who was a premier prospect, but for a Phoenix franchise that had been out of the playoffs for several years, the idea of taking the 'safe pick' feels like a disappointing approach. At the time, the Suns lacked a franchise point guard, with a mix of players from Tyler Johnson, Isaiah Canaan and Elie Okobo picking up starts throughout Ayton's rookie campaign.

Interestingly enough, international prospect Okobo, who was once thought of as a potential first-round selection was taken with the 31st pick out of France. He is no longer in the league.

Is it possible the Suns were shying away from using another top selection on an international player given just two drafts earlier they had used the fourth overall pick on Croatian talent, Dragan Bender?

Bender would play just 171 games with the franchise across three seasons, averaging 5.3 points and 3.8 rebounds.

Speaking with Basketball Network, former scout, Antonio Williams discussed part of the decision-making process when it came to moving towards Ayton ahead of Doncic or Young.

“With Deandre, one of the things was, you look at the things that he does, at his size when you combine the athleticism and the dexterity and the agility there are just things he can just roll out of bed and do," Williams said.

"Of course, we knew Luka and Trae Young were going to be great, but when we’re looking at Deandre again, there are just things that we felt he inherently can just roll out of bed and do that we didn’t have on our roster.”

The early returns
In many ways, the comparison between Ayton and Doncic was always going to be skewed. Doncic had the ball in his hands from opening night as a ball-dominant guard, while Ayton would ply his trade battling in the paint, working as a screen and roll man with Booker.

The young Suns finished Ayton's rookie campaign with a 19-63 record, though the big man impressed by averaging 16.3 points and 10.3 rebounds.

Doncic was box office from game one, finishing the season tallying 21.2 points, 7.8 rebounds and 6.1 assists on a Dallas team that finished 33-49.

From night one it was clear Doncic is a franchise-changing talent, immediately sparking the discussion on how he slipped through the fingers of multiple franchises.

The Suns would eventually find their point guard, trading for Chris Paul in a move that sparked a surprising run to the 2021 NBA Finals. Ayton was at times spectacular through the postseason run, producing a monster 22-point, 19-rebound effort in Game 1 of the Finals against Milwaukee.
Ayton's emergence on the biggest stage is further indication that Phoenix got a really, really good player on the night of the 2018 NBA Draft, which led many to believe he was in for a major payday.

What's next?
On the back of that breakout playoff run, Ayton loomed as the next player from the 2018 class to cash in with a major payday.

Doncic signed a five-year, $207 million supermax rookie extension as soon as possible this offseason.

Young also inked a five-year extension that can climb up to a value of $207 million with an All-NBA extension in the allotted time frame.

Jackson Jr. agreed to a four-year, $105 million dollar extension in Memphis.

Ayton on the other hand, could not come to an agreement with Phoenix on an extension, with ESPN's Adrian Wojnarowski reporting that ownership does not believe he is on the same tier as Doncic, Young, Shai Gilgeous-Alexander and other classmen that have received big-time contracts in the offseason.

"I mean, obviously, we're disappointed that we couldn't reach an extension agreement this offseason," Suns General Manager James Jones told The Athletic's Sam Amick. "Deandre is important for us. He means a lot to us and was vital in what we did and what we've done this past season."
Last month, the team came to terms on a four-year, $90 million deal with versatile wing Mikal Bridges. Bridges joins Devin Booker as a core piece locked up for the future, with Paul also inking a four-year deal worth up to $120 million in August.

Whether it be the Suns trio of Paul, Booker and Bridges, or the 2018 draft class of Doncic, Young and Gilgeous-Alexander, the collection of talent cashing in on major paydays all have something in common.

They aren't a center.

Ayton will now have the opportunity to sign an offer sheet with a rival team next offseason as a restricted free agent.

The failure to lock down Ayton caused many Suns fans to blame owner Robert Sarver, with the Suns a non-luxury tax team since 2010. Coming off a run to The Finals, potentially straining a relationship with your No. 1 overall pick from three years earlier is certainly a curious decision.

The 23-year-old has gotten off to an injury-interrupted start to 2021-22, appearing in just six games while battling with a leg contusion. A consistent double-double player as he has been throughout his career, Ayton is averaging 14.2 points, 11.3 rebounds and 1.2 assists per game thus far.

Ayton is sure to become one of the talking points of the 2022 free agency period, with the rising big man's relationship with the franchise seemingly tested through last summer's failed contract negotiations.

Now we wait for the next chapter of the 2018 Draft night story to unfold.

College Football Playoff rankings: Who are the top four teams in third CFP poll of 2021?

The Week 12 College Football Playoff rankings were easily adjustable for the selection committee. But they also set up to be a potentially chaotic final weekend of football.

Only one top-10 team in the most recent set of rankings lost on Saturday. That would be Oklahoma, a team the committee clearly didn't value in the first two sets of rankings, considering the Sooners' position at No. 8 overall in each of those weeks. The top seven teams remained the same following their loss, with Notre Dame, Oklahoma State and Wake Forest moving up to fill in the Sooners' spot.
A looming concern for this committee is what will happen if each of the one-loss Power 5 favorites win out the rest of the season. That could create a logjam of Oregon, Ohio State/Michigan/Michigan State and Oklahoma State/Oklahoma. That's to say nothing of the SEC, which could presumably lock up two spots should Alabama beat Georgia in the SEC championship.

Then there's the question of a potentially undefeated Cincinnati team, which if left out would join UCF as a twice-undefeated Group of 5 team that never got a chance to compete for a title.

There's still plenty of football left to be played, including the two Michigan teams vs. Ohio State in the Big Ten; Alabama taking on two ranked teams in the last three weeks of the season; Bedlam; and a not-insignificant end to the season for Cincy, which plays a ranked team in Houston.

It's all shaping up to be a wild, fun and potentially chaotic stretch to end the season. Best take a deep breath while you're still able. Until then, here's the latest top 25 rankings from Week 12:

Why isn't Trey Lance starting? 49ers' commitment to Jimmy Garoppolo makes messy QB situation

49ers fans waiting for the return of the "Trey Area" may have to wait a little longer.

The 49ers sending away two future first-round picks for the No. 3 overall pick for, what turned out to be, Trey Lance in the 2021 NFL Draft meant that the future was now. Or later. Or, apparently, eventually.
Kyle Shanahan and the 49ers have maintained that the best way to develop their prized QB prospect is to keep him on the bench, a strategy that may or may not work out long-term for them.

With Jimmy Garoppolo still a serviceable starter for San Francisco, the 3-5 start has fans calling for a change at the quarterback spot, leading to many wondering why Lance isn't starting. While draft philosophies differ, one thing is certain: The 49ers spent a lot of future draft capital for a guy who's gotten a very small sample size of work so far this season.

Shanahan's comments haven't painted a pretty picture for Lance's starting prospects in 2021, either.

Why isn't Trey Lance starting?
The answer: Anyone's guess.

While Lance got an opportunity to fill in for Jimmy Garoppolo in Week 5 vs. the Cardinals, he's been on the sidelines since then. Through a bye week, a knee injury and Garoppolo getting the opportunity to start once again, the 49ers have resisted the urge to let Lance see the field. Lance last got a snap in Week 5.

While Lance came out of college as something of a project, it seems like the 49ers' direction is to do more to try and develop Lance for the future than to shoehorn him into situations now after attempting to earlier in the season.

In late October, head coach Kyle Shanahan explained why Lance hasn't been given a longer leash to start:

“We didn’t draft Trey to just fix this year," Shanahan said. "We drafted him so he could be the quarterback of the future and that’s a matter of time. We are not playing him just because what our record is, or just because."

There's also the matter of Jimmy Garoppolo, who has played "all right" (Shanahan's words) despite missing a game with an injury. ESPN's Dan Graziano reported that he doesn't feel that Shanahan will make the change to Garoppolo anytime soon — not as long as Garoppolo is playing, well, all right.

On Halloween, Lance was seemingly healthy and ready to go. Shanahan, though, didn't want to risk putting Lance on the field in the event that Garoppolo was injured.

To that end, the question remains: Not that Lance's usage rate was out of this world, but why were the 49ers more willing to use Lance early on in the season (129 snaps in total through Week 5) and not now?

The resistance to want to use Lance continued in this past weekend: Following the rough Week 9 loss to an undermanned Cardinals team, Shanahan was asked if he'd consider making a QB change for the Niners' Week 10 game vs. the Rams.

"Probably not, but definitely not thinking about those things right now. I’m thinking about this game and the rest of our team," Shanahan said post-game.

Defenses have been playing the 49ers passing game tighter, with Garoppolo's propensity to work short throws and the middle of the field (as the Shanahan system accounts for). Garoppolo's ability to stretch the field has always been something of a question, something that Lance's physical traits would allow him to do.

But, come hell or high water, it sounds like it's going to be Garoppolo — for now.

NBA after Kenosha: A timeline of basketball's response to protests through Kyle Rittenhouse trial

As the NBA has grown in popularity, so has the influence of its players. In recent years, members of the basketball community have raised their voices and stepped up their efforts in advancing social justice.

One particular date served as a major turning point in the NBA's movement. On Aug. 23, 2020, Jacob Blake, a Black man, was shot multiple times in the back by Rusten Sheskey, a white police officer, in Kenosha, Wisc. The shooting left Blake paralyzed from the waist down and sparked several protests against police brutality and systemic racism in the United States.
At the same time, the NBA season was playing out inside the Florida "bubble" as the news emerged about the shooting, leaving the entire NBA community with the difficult task of staying engaged as the 2019-20 season resumed amid a global pandemic while also speaking to events happening in the real world.

Then, basketball suddenly stopped.

Bucks lead response in NBA 'bubble'
On Aug. 26, 2020, the Bucks were scheduled to face the Magic in Game 5 of their first-round series. Milwaukee players never took the floor for pregame warmups, though, and Orlando players returned to their locker room once it became clear that the Bucks did not intend to play.

Hours after the game was supposed to tip off, Bucks guards Sterling Brown and George Hill delivered a team statement calling for the Wisconsin State Legislature to "take up meaningful measures to address issues of police accountability, brutality and criminal justice reform" in the wake of the Blake shooting. Milwaukee players also attempted to reach Josh Kaul, the attorney general of Wisconsin, according to The Athletic's Shams Charania.
The NBA then announced that the three playoff games scheduled to be played that day had been postponed.

"The NBA and the National Basketball Players Association today announced that in light of the Milwaukee Bucks' decision to not take the floor today for Game 5 against the Orlando Magic, today's three games — Bucks vs. Magic, Houston Rockets vs. Oklahoma City Thunder and Los Angeles Lakers vs. Portland Trail Blazers — have been postponed," the league said in its statement. Game 5 of each series will be rescheduled."

Milwaukee's decision reportedly caught the rest of the NBA off-guard, including the team's front office, but Bucks ownership offered full support to the players.

"Although we did not know beforehand, we would have wholeheartedly agreed with them," Marc Lasry, Wes Edens and Jamie Dinan said in a joint statement. "The only way to bring about change is to shine a light on the racial injustices that are happening in front of us. Our players have done that and we will continue to stand alongside them and demand accountability and change."

Tense meeting after 'bubble' boycott
Once games were postponed, multiple reports emerged indicating players would hold a meeting that evening to discuss the state of the season. Coaches were in attendance as well, but they were asked to leave at one point, according to ESPN's Zach Lowe.

A few key items from that meeting:

Players talked about voting and police reform and what team owners must do in order for the season to proceed, according to Sports Illustrated's Chris Mannix, who also noted members of the Bucks and Raptors were particularly outspoken during the meeting.
The Clippers and Lakers voted to boycott the season, per multiple reports, though ESPN's Adrian Wojnarowski clarified those votes were part of an informal poll. Every other team voted to continue play, according to Charania.
There was reportedly frustration with how the Bucks handled the boycott, and some players wanted an explanation for why they didn't alert other teams of their decision. Celtics forward Jaylen Brown, however, supported the Bucks and said they didn't need to explain anything.
Kawhi Leonard and LeBron James were "adamant" about not finishing the playoffs, according to Brad Turner of the Los Angeles Times. James reportedly left the meeting early and was followed by the rest of the Lakers and Clippers.
Michele Roberts, the executive director of the NBPA, laid out the financial ramifications of boycotting the season, including the possibility of owners terminating the collective bargaining agreement and a future lockout, per Wojnarowski.
A source told The Athletic's David Aldridge the meeting ended "ugly" and there was uncertainty about what would happen the next day.

2020 NBA playoffs resume
The league's Board of Governors conducted an emergency call with NBA commissioner Adam Silver on Aug. 27, 2020, per multiple reports. NBA players also had a meeting scheduled at that time. Players eventually decided to resume the 2020 NBA playoffs.

James and other players reportedly changed positions after initially supporting a boycott of the season, saying it was in the best interest of the players' movement to resume the season. A major source of frustration in the previous meeting "stemmed from players not being on the same page," according to Chris Haynes of Yahoo Sports.

The NBA and the NBPA then announced three new initiatives after discussing what steps needed to be taken in support of social justice and racial equality:

Creating a social justice coalition, which includes players, coaches and owners and focuses on increased access to voting, civic engagement and police and criminal justice reform
Working with local officials to turn NBA arenas into voting centers for the November general election
Airing public service ads during playoff games to increase engagement in elections and raise awareness of voter access
All parties agreed to resume playoff games on Aug. 29, 2020.

NBA reaction to Jacob Blake ruling
On Jan. 5, 2021, Kenosha County District Attorney Michael Graveley announced that no charges would be brought against Sheskey in the shooting of Blake. The Wisconsin Department of Justice said that Blake had a knife in his possession.

"Jacob Blake, while actively resisting, arms himself with a knife," Graveley said (via CNN). "It's absolutely incontrovertible that Jacob Blake was armed with a knife during this encounter. … All the discussion that he's unarmed contradicts even what he himself has said multiple times."

However, an attorney for Blake's family didn't believe that Blake ever posed a threat to officers.

"I think that's completely bogus and I think that is just a rationalization to try to show what is really, essentially, an intentional act," B'Ivory LaMarr said after Graveley's announcement. "It's not against the law to have a knife. People have knives for a variety of different reasons. Jacob Blake is privy to having a knife."

Graveley added that Blake would also not face charges.

Blake's legal team shared their disappointment in the decision, as did NBA players upon hearing the news. James called the results of the investigation a "blow to the heart and to the gut." Wesley Matthews, who was part of the Bucks team that led the "bubble" boycott, described the development as "disheartening."

"It's upsetting as a human being that justice isn't justice. It's tough," Matthews said. "But it can't knock us off our path that we're trying to get to, which is equality and just simply right and wrong."

The U.S. Justice Department announced on Oct. 8, 2021, that it would not pursue charges against Sheskey.

Kyle Rittenhouse shooting
In the aftermath of the Blake shooting, one of the protests in Kenosha turned violent. On Aug. 25, 2020, Kyle Rittenhouse, then a 17-year-old from Antioch, Ill., shot and killed two men and wounded another man.

Rittenhouse, who claims that he acted in self-defense, faces the following charges:

First-degree reckless homicide, use of a dangerous weapon
First-degree recklessly endangering safety, use of a dangerous weapon
First-degree intentional homicide, use of a dangerous weapon
Attempted first-degree intentional homicide, use of a dangerous weapon
First-degree recklessly endangering safety, use of a dangerous weapon
Possession of a dangerous weapon by a person under 18
First-degree intentional homicide carries a mandatory life sentence.

A jury for the Rittenhouse trial was selected on Nov. 1, and the trial began on Nov. 2.

LeBron James reaction to Kyle Rittenhouse trial
Rittenhouse took the stand on Nov. 10 and told jurors that he shot the men because he had to "stop the people who were attacking me." He also claimed that he was in Kenosha to protect private property and provide first aid.

At one point while he was on the stand, Rittenhouse broke down in tears, leading to a brief break. James posted on Twitter in response to a video of the moment captured by USA Today.

"Man knock it off!" James tweeted. "That boy ate some lemon heads before walking into court."
What happens next in Kyle Rittenhouse trial?
Testimony in the trial concluded on Nov. 11 after jurors heard from more than 30 witnesses. Closing arguments are expected to begin on Nov. 15, and each side will have two and half hours for their closing arguments. The judge will also give the jury instructions before final deliberations.

Regardless of where the jury lands on the charges, there will be a strong reaction to the ruling in the Rittenhouse trial, and it is expected that NBA players will once again let their voices be heard.
