Jost Capito is stepping down as the principal of Williams, the team announced on Monday.

Capito had been in the position for two years having initially joined the team as CEO in December 2020.

The 64-year-old leaves his role after Williams finished bottom of the constructors' championship standings in 2022, having now done so four times in the last five years.

In Williams' announcement, Capito said: "It has been a huge privilege to lead Williams Racing for the last two seasons and to lay the foundations for the turnaround of this great team. I look forward to watching the team as it continues on its path to future success."

Williams become the second team in Formula One to head into 2023 without a team principal appointed, after Ferrari announced in November that Mattia Binotto was to step down at the end of the year.

It is rumoured Sauber's Frederic Vasseur could soon be the third team principal to leave his job, amid speculation he could replace Binotto at Ferrari.

Brock Purdy and his family enjoyed a special moment after his stunning performance in his first start for the San Francisco 49ers, which saw him beat Tom Brady in a blowout 35-7 victory.

Purdy impressed when pressed into action in relief of the injured Jimmy Garoppolo last week, helping the Niners to a 33-17 defeat of the Miami Dolphins.

His second act was even more impressive, Purdy completing 16 of his 21 passes for 185 yards and two touchdowns while also rushing for another score.

The seventh-round rookie, the final pick in this year's draft, had the Levi's Stadium crowd in the palm of his hand as the Niners brushed aside the Bucs to move to 9-4.

They chanted his name as the 49ers took complete command in a remarkable first half. His family had prime seats for the occasion, having originally bought tickets before the Garoppolo injury to see Brady play, and the moment was too much for his father, who was pictured in tears as he watched his son make history.

Purdy became the first quarterback to beat seven-time Super Bowl champion Brady in his first start, and was quick to embrace his family as he left the field.

He told his post-game press conference: "I saw them right after the game and, you know, the emotions on their face and just the way they look down at me from up on the railing, it just means a lot because just throughout my whole life, the ups and downs of playing quarterback in general, high school and college, they're the people at home that just believe in you and they always see the best in you.

"And so, they've believed in me even though I was the last draft pick and all that kind of stuff.

"They've always been telling me you're good enough and we know that you can do it. And so, to see them after that performance meant a lot to me and so very blessed to have them as my family."

Niners head coach Kyle Shanahan will have no shortage of belief in Purdy, who had an interception negated by a penalty prior to his second touchdown pass, after their destruction of the Bucs.

"I think he did an awesome job. I think all you guys saw that, but he made a ton of plays," said Shanahan. "Made the plays that were there, made some plays that weren't there.

"He did a great job in the pocket. Had one mistake there, he was fortunate that we got that one back.

"He didn't hesitate. I think he threw a touchdown the next play, which was really cool, but it's really impressive how he played and I thought it was similar to the week before.

"They [the Bucs] mix in a lot of pressures, but they do that in every game. Some are to stop the run, some are to come after the quarterback. They mixed up a lot of zone coverages too, so there was no real theme of the day.

"They mixed up a bunch of stuff and he had to go against everything, so he did a good job with the variety of things he saw."

Purdy did suffer an oblique injury, but that was not the reason he was eventually withdrawn from a lopsided game. The 49ers visit the Seattle Seahawks on Thursday with a chance to clinch the NFC West title.

"We'll see how it goes this week," Purdy said of the injury. "Just felt a little tight at the end, just from taking some hits.

"But honestly man, like if I needed to play throughout the rest of the game, I definitely would have. So, I'm going to get some treatment on it and be ready to roll."

Fabio Quartararo has suffered a broken hand after crashing during a motocross training session on Sunday.

The 2021 MotoGP champion revealed he did not require surgery on damage done to his left hand.

He tweeted: "Yesterday I had a crash during my motocross training and I suffer a little fracture on my left hand. No surgery needed, time to recover."

It is another blow for Quartararo after he was unable to retain his title in the premier class this year.

The Frenchman finished second in the standings behind Francesco Bagnaia, who was crowned champion at the season-ending Valencia Grand Prix.

Monster Energy Yamaha rider Quartararo was 17 points adrift of the Italian.

Testing for the 2023 season gets under way in Sepang on February 5, with the first race coming in Portugal on March 26.

Ash Barty is adamant she "absolutely fulfilled every ounce" of her tennis aspirations following her shock retirement earlier this year.

The three-time grand slam winner was at the peak of her powers when, in March, she made the surprise decision to call time on her tennis career at the age of 26.

The former world number one and reigning Australian Open champion later revealed to friend and former player Casey Dellacqua that she was 'spent' and no longer had the 'physical drive' or 'emotional want'.

Following her triumph at Melbourne Park, making her the first home women's singles champion since Chris O'Neil in 1978, Barty became the first player to win the Newcombe Medal on five occasions.

She maintained her record of having won the award, the highest individual honour in Australian tennis, every year since it was first presented in 2017.

"This has obviously been a very big year in my career and in my life," said Barty, who beat Wimbledon runner-up Nick Kyrgios, US Open mixed doubles champion Storm Hunter, Ajla Tomljanovic and Alex De Minaur to the accolade.

"We've had exceptional change, we've had an amazing year of celebrating a journey of not only myself, but my team, and there is so much to be proud of.

"I stand here very proudly knowing that I absolutely fulfilled every ounce that I could to this beautiful sport that brought me so much more than I could have ever dreamt."

Shaq Thompson feels the Carolina Panthers' backing of interim head coach Steve Wilks is proving key following Sunday's 30-24 victory over the Seattle Seahawks.

Wilks took charge of the team following the axing of Matt Rhule after a 1-4 start to the season and has had a dramatic stint in charge of the team.

After trading away star running back Christian McCaffrey to the San Francisco 49ers before the deadline and then releasing Baker Mayfield last week, the Panthers have had a turbulent spell of change.

But, sitting 4-4 under Wills, they are making an unlikely push for the playoffs after their win in Seattle.

Wilks is receiving a lot of support in his bid to land the head coach job on a permanent basis and linebacker Thompson has made it clear the players are in his corner.

"We ride behind Wilks," he told the team's website after the Panthers forced Seahawks quarterback Geno Smith into two interceptions.

"He came in here, he's a true alpha, he's a true leader, and guys follow behind him. He's done amazing. Look what we've been going through."

Victory in Seattle put the Panthers just one game behind the Tampa Bay Buccaneers in the NFC South, with Thompson believing the team's bye week provided a push to secure the win.

"Once we had that first day of practice, we knew what type of team we were going to be [in this game]," he added.

"We talk about playoff mentality, and I told them boys last night, I talked to the team, I said, 'If you want to be a playoff team, these are the games you got to win — in these environments'.

"And these guys showed up, they played, we created turnovers and got the offense the ball back in great field position."

Meanwhile, the Seahawks endured their third defeat in four games, having won four in a row prior to that streak, with head coach Pete Carroll disappointed in the performances against sides who sit under .500 this season.

"It's the manner [of the loss]," he said after the game. "This really happened on the ground.

"I'm really disappointed in that because I pride myself in thinking we can scheme our way into all kinds of good things to offset that, and I've got to do better."

The Seahawks face a tough end to the regular season, facing division rivals the 49ers in Week 15 before tackling AFC top-seed contenders the Kansas City Chiefs, then bringing the season to a close against the New York Jets and Los Angeles Rams.

Carolina, meanwhile, will next host the Pittsburgh Steelers, who also hold a 5-8 record.

Nick Kyrgios will play the French Open for the first time since 2017 next year because his partner wants to visit Paris, though he would prefer to stay at home.

Kyrgios has never been beyond the third round at Roland Garros, last appearing at the event in 2017 – when he suffered a second-round defeat against Kevin Anderson.

Last year, the Australian labelled the French Open "the worst grand slam" and called for the competition to be "taken off the calendar altogether".

However, Kyrgios now says he will end his absence from the Paris event, though his reasons for doing so are not tennis related.

"My girlfriend wants to know Paris, so I'm going to play at Roland Garros 2023," Kyrgios told reporters in Saudi Arabia.

"It will be good for me to earn some more money, although I would have preferred to stay at home.

"I know I can do great results on clay. I beat Roger [Federer], [Stan] Wawrinka, I played a final in Estoril. My girl wants to get to know the city so I will have to go this year."

Kyrgios achieved two of his four best grand slam runs in 2022, losing the Wimbledon final to Novak Djokovic before exiting the US Open at the quarter-final stage against Karen Khachanov.  

Tampa Bay Buccaneers coach Todd Bowles says his side must decide for themselves if they want to be involved in the postseason conversation after a humiliating loss to the San Francisco 49ers.

The Tom Brady-led Florida outfit were handed a 35-7 drubbing out west at Levi's Stadium, to take them to a 6-7 record for the season.

Though they remain on top of NFC South with a handful of games to go, the prospect of the Buccaneers launching another dynamic run through the playoffs looks slim at best on their current form.

Bowles, who guided the team to glory at Super Bowl LV almost two years ago, says his side need to take a look in the mirror and decide how they will show up for the rest of the campaign.

"We've got to decide what team we want to be," he stated. "We can't be one set of Bucs and another set of Bucs. It's got to mean something.

"Either we want it or we don't. We can't care more than everybody else. As a coach, you don't go out on the field, but we got out-coached, so we're not excused from this at all.

"We got outplayed as well. As a team, as a group, we've got to buckle down and decide what our fate is in the next few weeks."

A superior record over the Carolina Panthers (5-8) means there is still some wiggle room for the Buccaneers, whose fate remains within their own hands.

Wide receiver Mike Evans accepted the team are struggling to make their familiar tactics stick this season, and that it could yet cost them dearly.

"We're just not making plays," he added. "The plays that we're used to making in previous years, we're just not making them as consistent. I don't know what it is. We're just not connecting like we usually do."

 Zion Johnson feels "things are starting to click" for the Los Angeles Chargers after they boosted their playoff hopes with a 23-17 win over the Miami Dolphins on Sunday.

Quarterback Justin Herbert was outstanding at SoFi Stadium as the Chargers bounced back from their Week 13 defeat to the Las Vegas Raiders in style.

While Herbert claimed the record for the most pass yards in a player's first three seasons in NFL history on Sunday, Mike Williams also stood out with 116 yards from six receptions on his return from an ankle sprain.

Speaking after the Chargers improved to 7-6 for the season, guard Johnson focused on the impact of players returning to full availability. 

"I feel like this is probably our first game since Week 1 where we had most of our guys active," Johnson said. 

"I think you can really tell with how explosive some of the passes were down the field and some of the things we were doing. 

"I'm just really glad that guys are getting healthy, and things are starting to click."

Wide receiver Williams set the Chargers on their way with a second-quarter touchdown, and head coach Brandon Staley was in no mood to play down the importance of his return.

"When you get Mike back in this movie, it just looks different, it feels different," Staley said. "There's just more available to you. Those guys were able to connect tonight.

"Nine guys caught passes tonight. That's the offense that we like to play, where people touch the ball."

Deebo Samuel likely sustained a high ankle sprain rather than a fracture during the San Francisco 49ers' 35-7 win over the Tampa Bay Buccaneers, head coach Kyle Shanahan said.

Samuel's season appeared to be in jeopardy when he was carted off in the first quarter of the 49ers' victory on Sunday, after his knee was trapped and twisted under a mass of bodies.

The All-Pro wide receiver was unable to get to his feet following the concerning incident, but encouraging reports subsequently suggested he had avoided a major injury.

49ers coach Shanahan offered a positive update on Samuel's condition after the win, telling reporters the wide receiver did not suffer a fracture.

Shanahan added Samuel's injury was "most likely" a sprain, though reports said the 26-year-old would undergo tests on Monday.

The 49ers had already established a commanding 21-0 lead before Samuel's injury, and they entered half-time 28-0 up in what represented a dream first start for stand-in quarterback Brock Purdy.

"Everyone knows how much Deebo means to us, but half-time is so hectic and it was awesome to finish that half with the score," Shanahan said of losing Samuel.

"We didn't really do anything differently after half-time."

Linebacker Dre Greenlaw, meanwhile, praised the team's reaction to Samuel's exit.

"We hate to see guys go down, especially one of our leaders like Deebo," he said. "You've just got to go with the punches and just keep fighting and that's what everybody on this team did.

"That's just the type of team that we've got. You get hit in the mouth and you've got to just keep fighting."

Zion Williamson was in no mood to downplay the New Orleans Pelicans' top ranking in the West after inspiring the team to another victory over the Phoenix Suns on Sunday.

Having defeated the same opponents two days earlier, the Pels cemented their position as Williamson once again put up 35 points in a 129-124 overtime triumph.

It represented a seventh straight win for the high-flying Pels, who are top of the Western Conference with an 18-8 record.

While there is still plenty of basketball left to be played this season, Williamson said the team's aim is to build on their status as pacesetters.

"We're number one in the West right now," Williamson said. 

"I know to a lot of people that's not a big deal because it's still early in the season, but for us to have that ranking right now, that's big.

"We want to not only hold on to it but build on it.

"The Suns, they've earned their resume; they're a great team. So, for us to get two back-to-back wins against them, that's big for our confidence."

Head coach Willie Green said of Williamson: "Zion is – he's a matchup problem. 

"He just attacks. And when he attacks like he does, he's just tough to cover. It's incredible what he can do."

The Suns, who were without Devin Booker, were once atop the West but now sit fourth and are on a four-match losing streak.

Star man Chris Paul believes now is not the time to panic, however.

"Let it slide off. Realise it's a long season," Paul said. "We know we definitely have to get better and right some things here. But it's not do or die yet."

New York Jets head coach Robert Saleh has reassured Mike White is his first-choice quarterback after copping multiple hits in Sunday's 20-12 loss to the Buffalo Bills.

White has stepped in as the Jets' starting quarterback for the past three games from Zach Wilson, completing 27-of-44 passing for 268 yards with no touchdowns or interceptions on Sunday.

The 27-year-old QB, who threw three touchdowns against the Chicago Bears before going without a TD in his past two games, copped a physical pounding from the Bills' defense, and was sent for a hospital visit after the game to check his ribs.

White had also undergone evaluation in an ambulance in the stadium tunnel in the third quarter where Saleh said he "checked out good" allowing him to play out the game.

Saleh along with several Jets players were full of praise for White for his toughness after the loss to the AFC East-leading Bills.

"I thought he showed resolve, toughness, everything we've been seeing," Saleh told reporters. "He's a good player."

Saleh responded with "for sure" when asked if White would start against the Detroit Lions next Sunday if healthy, in a sign that he is now their preferred QB from Wilson or veteran Joe Flacco.

Offensive tackle Duane Brown added about White: "He took some shots and I know he was hurting. He didn't want to be out of the game — he wanted to finish.

"Major heart, toughness. He's a dog, that's the bottom line, but we have to do a better job of protecting him."

Jets center Connor McGovern also hailed White, who was taken in the fifth round of the 2018 NFL Draft.

"He's willing to do whatever it takes to win," he said. "That's what every guy in this locker room, if they aren't that way, they need to be that way. I believe everybody is that way.

"Today, Mike was unfortunately an example of that. Guys are willing to do whatever it takes to get the Jets to the playoffs and beyond."

Joel Embiid downplayed the enormity of his historic 53-point performance for the Philadelphia 76ers on Sunday, insisting that his teammates simply fed the hot hand.

Embiid reached 50 points for the second time this season, both occurring in the past nine games as the Sixers won 131-113 over the Charlotte Hornets.

The center also joined Allen Iverson and Wilt Chamberlain as the only players in 76ers franchise history to have two 50-point games over a nine-game stretch.

Embiid also joined Chamberlain as the only Sixers in franchise history with at least 30 games of 40 points and 10 rebounds.

"We won," Embiid told reporters. "It's good to do that when you win. It would suck to have those type of scoring nights if you lose.

"I'm just happy it's contributing to winning. Whether I'm scoring a lot, but especially if I'm scoring a lot, at the end of the day, what matters is if it brings us the win."

He added: "We have a saying that you gotta feed the hot hand. My teammates, if I just scored once, it doesn't matter.

"If anybody on the team, if they just score once, you gotta keep feeding them until the defense stops them once or twice or three times. In that situation, I just kept scoring, and they just kept giving me the ball."

Embiid's dominance was underlined by a second-quarter stretch where he scored 15 points in a row. He shot 20-for-32 from the field, making 11-of-11 free-throws with 12 rebounds.

"Every single time, it seems to bring us the win so just gotta keep trying to be efficient and try to play with my teammates," Embiid said.

"Good things happen when you’re worried about the right things and that’s moving the ball and the ball just finds me."

Teammate James Harden, who laid off 16 assists with 19 points, praised the MVP contender.

"He was in attack mode for the entire game," Harden said. "He made scoring look easy tonight, you know what I mean? He was just in attack mode, getting to the basket, his jumper was falling, he had an aggressive night tonight."
