Kevin Magnussen has returned to Formula One after signing a multi-year deal with Haas for 2022, replacing outgoing Russian driver Nikita Mazepin.

The American-owned team parted ways with Mazepin ahead of the season following Russia's invasion of Ukraine.

Magnussen is back in F1 having left Haas at the end of the 2020 season after four years with the team. He has also previously driven for McLaren and Renault.

The Dane has since participated in sportscars and IndyCar in the United States, and had been about to join Peugeot's World Endurance Championship squad before the call came to return to Haas.

Magnussen joins up with the team's other driver, Mick Schumacher, son of German great Michael Schumacher.

Mazepin spoke to the media on Wednesday, four days after his sacking was announced by Haas, and he described that ousting as "an injustice".

His father, Dmitry, has close ties to Vladimir Putin, holding face-to-face business talks with the Russian president as recently as January. Dmitry Mazepin is deputy chairman of Uralkali, the potash fertiliser producer that has been a major financial backer of Haas.

Haas also cut the sponsorship link with Uralkali with immediate effect, leading to a demand on Wednesday from the Russian firm for reimbursement of funds it had invested ahead of the new season.

The Russian Grand Prix for 2022 has been cancelled, with F1 announcing this week it has terminated its deal for future races in the country.

Josh Navidi has been passed fit to start his first Test for almost a year when Wales face leaders France in the Six Nations on Friday.

Navidi last played for his country against Les Bleus in the 2021 Six Nations, but will start at open-side flanker at the Principality Stadium after recovering from a shoulder injury.

Seb Davies comes in at blindside flanker, as Ross Moriarty and Taine Basham drop out of the side following a defeat to England at Twickenham that leaves the holders in fifth place.

Prop Gareth Thomas and centre Jonathan Davies also get the nod for the round-four showdown in Cardiff.

Tomas Francis and Josh Adams have been given the green light to start after coming through the return to play protocols.

Nick Tompkins will not feature after suffering a concussion in Saracens' win over Leicester Tigers last weekend. Wing Louis Rees-Zammit returns, but will be among the replacements.

Wales head coach Wayne Pivac said: "Josh is a fantastic player and has played well for us in the past.

"He’s come back before straight back into the side so having 80 minutes under his belt for Cardiff we think that’s enough for him and we look forward to him being back out there bringing that experience.

"He’s a very good player and has played at this level on many occasions so that’s going to be great for us.

"Seb at six just gives us a little bit more size. It helps the lineout, but also in the wider channels where he often runs he’s got the skill set to trouble a few defenders out wide.

"I think Gareth made a really big impact for us last week as did a number of players and so he gets to start."

Wales team: Liam Williams, Alex Cuthbert, Owen Watkin, Jonathan Davies, Josh Adams, Dan Biggar (captain), Tomos Williams; Gareth Thomas, Ryan Elias, Tomas Francis, Will Rowlands, Adam Beard, Seb Davies, Josh Navidi, Taulupe Faletau.

Replacements: Dewi Lake, Wyn Jones, Dillon Lewis, Ross Moriarty, Jac Morgan, Kieran Hardy, Gareth Anscombe, Louis Rees-Zammit.

France head coach Fabien Galthie has been forced into one change for Friday's Six Nations clash with Wales and fears others may yet be ruled out with coronavirus.

Les Blues lead the way at the top of the standings with three wins from three ahead of their trip to the Principality Stadium to face a struggling Wales side.

However, the visitors will be without wing Damian Penaud and second row Romain Taofifenua after both players tested positive for COVID-19.

Losing Penaud is a big blow for Galthie as the 25-year-old has beaten 10 defenders in this year's tournament, the joint-most of any player alongside Scotland's Darcy Graham.

Indeed, Penaud has faced just 13 tackles in total across France's three matches, with his tackle evasion rate of 77 per cent the best of any player.

Yoram Moefana will switch to the right wing in the absence of Penaud, who started the 36-17 win over Scotland last time out, with Gabin Villiere drafted into the side on the left.

After losing Penaud and Taofifenua, Galthie is now awaiting the results of further PCR tests ahead of making the trip to the Welsh capital.

"We were notified this morning that they were positive so we had to make last-minute changes," Galthie told a news conference on Wednesday.

"We are preparing for other changes. We have no additional information yet, but we need to know by Thursday [if more changes will be made]."

In more positive news for France, captain and reigning world player of the year Antoine Dupont has recovered from a knock sustained in training to make the starting XV.

Les Blues have won their last six Test matches, making this their best run of form since 2006, and have won their last two Six Nations meetings with Wales.

France's 27-23 victory on their last trip to Cardiff in 2020 was their first Six Nations victory in the Welsh capital since 2010, which was also the last time they won the tournament.

France team: Melvyn Jaminet, Yoram Moefana, Gael Fickou, Jonathan Danty, Gabin Villiere, Romain Ntamack, Antoine Dupont (c); Cyril Baille, Julien Marchand, Uini Atonio, Cameron Woki, Paul Willemse, Francois Cros, Anthony Jelonch, Gregory Alldritt

Replacements: Peato Mauvaka, Jean-Baptiste Gros, Mohamed Haouas, Thibaud Flament, Dylan Cretin, Maxime Lucu, Thomas Ramos, Matthis Lebel.

Dumped driver Nikita Mazepin claims to have received messages of support from at least four fellow drivers, but the Russian said former Haas team-mate Mick Schumacher was not among them.

Mazepin spoke to the media on Wednesday, four days after his sacking was announced by American-owned team Haas, and he described that ousting as "an injustice".

Russia's invasion of Ukraine, rather than his results on the track, is what has cost the 23-year-old his seat for 2022.

Mazepin's father, Dmitry, has close ties to Vladimir Putin, holding face-to-face business talks with the Russian president as recently as January. Dmitry Mazepin is deputy chairman of Uralkali, the potash fertiliser producer that has been a major financial backer of Haas.

As well as ousting Mazepin, Haas cut the sponsorship link with Uralkali with immediate effect, leading to a demand on Wednesday from the Russian firm for reimbursement of funds it had invested ahead of the new season.

Mazepin is smarting over his treatment by Haas and, according to L'Equipe, he said: "I had no message from Gunther Steiner, the team boss, and nothing from Mick Schumacher either. It is in these moments that we measure what people really are.

"I have always trusted Gunther 100 per cent and, after what has just happened, understand that at 23 I was not ready to experience such a disappointment.

"I don't want to speak in front of you about Haas and the men of the team, when they are not there. I will tell them what I think directly if I have the opportunity to meet them again."

Asked who had sent him messages, Mazepin said: "Sergio Perez, Valtteri Bottas, George Russell and Charles Leclerc. I appreciated it.

"Simple messages telling me to keep my head up, that they shared my pain, because they know the sacrifices you have to make to get to F1."

On social media, Mazepin declared he would be setting up a foundation "to help athletes who have been blocked from competing for political reasons". That statement faced swift ridicule from Twitter users.

Mazepin's F1 career may be over after only one season, with no guarantee he will find another drive in future.

After governing body the FIA gave Russian drivers permission to compete under a neutral flag, Mazepin was hopeful he could be able to race in 2022, before Haas decided to cut ties.

"I will abstain from any political commentary but, personally, I see my eviction as an injustice," he said. "Especially after the FIA ​​indicated that Russian drivers could race under a neutral banner. Exactly like tennis players under the ATP umbrella."

Haas will miss the start of Formula One pre-season testing in Bahrain due to the late arrival of their freight.

The plane that was due to transport the team's cargo from the United Kingdom was reportedly grounded by technical problems.

Although the freight arrived in Bahrain on Tuesday evening, that left the team short of time to be ready for the beginning of testing on Thursday.

Haas said they plan to have the car ready to be out on track later in the day.

"The team's freight arrived late last night to the circuit in Bahrain," a Haas statement said.

"This delay will impact our programme, but we are targeting being out on track for the second session Thursday afternoon with Pietro Fittipaldi driving the VF-22."

The disruption comes after Haas cancelled the contract of Russian driver Nikita Mazepin amid the war in Ukraine and also terminated their commercial partnership with Uralkali.

Uralkali, a Russian fertiliser producer, on Wednesday stated it will request an immediate reimbursement of sponsorship payments it has made for the 2022 season. The company described Haas' decision as "unreasonable", adding that sport "should always be free of politics and pressure from external factors".

Haas are yet to announce who Mick Schumacher's team-mate will be, just over a week before the first race of the year in Bahrain. Fittipaldi is their test and reserve driver.

Novak Djokovic is at the centre of another saga after being included in the draw for the BNP Paribas Open at Indian Wells.

The former world number one was handed a second-round clash against either David Goffin or Jordan Thompson.

All 32 seeds receive a first-round bye, so although the men's singles begins on Thursday at the California desert event, Djokovic is not due to be in action until the weekend.

However, it remains to be seen whether he is allowed into the United States, given he has declared he has not received any vaccination against the COVID-19 virus.

Tournament organisers admit they do not know whether Djokovic will play.

They said in a statement on the event's official Twitter feed: "Novak Djokovic is on the tournament entry list, and therefore is placed into the draw.

"We are currently in communication with his team; however, it has not been determined if he will participate in the event by getting CDC approval to enter the country.

"We will provide updates in the future as we learn more."

The CDC is America's Centers for Disease Control and Prevention, which lays down requirements for non-US international citizens travelling to the United States.

Within its rules, it is stated that all non-US citizens travelling to the US "must be fully vaccinated with the primary series of an accepted COVID-19 vaccine", adding that "only limited exceptions apply".

Djokovic tested positive for COVID-19 in December, and at one stage it appeared that recovering from that, and having post-virus antibodies, would be enough to allow him to travel to Melbourne and play in the Australian Open.

That proved not to be the case, with Djokovic twice detained after arriving in Australia before being deported.

He has since made his return to tennis at the Dubai Tennis Championships, where he surprisingly lost in the quarter-finals to Jiri Vesely.

The 34-year-old Serbian has been overtaken for the rankings top spot by Daniil Medvedev, the Russian who will be playing under a neutral flag while his country's military invasion of Ukraine continues. Medvedev will begin against Alexei Popyrin or a qualifier at Indian Wells.

Klay Thompson realised a dream as he shared the court with Will Ferrell before the Golden State Warriors beat the Los Angeles Clippers on Tuesday.

Ferrell warmed up with the Warriors dressed in a Jackie Moon outfit from the film Semi-Pro that he starred in for the 2008 movie.

Five-time NBA All-Star Thompson never grew tired of watching the film during a long rehabilitation from major knee and Achilles surgeries.

Ferrell might be cast for another appearance at Chase Center after Golden State snapped a five-game losing streak with a commanding 112-97 victory.

Thompson, who scored 20 points and claimed five rebounds, dressed as Moon for Halloween three years ago and was pinching himself after Ferrell helped the Warriors stop the rot.

He said: "When I had some dark days, I would put that movie on, and it would make me smile. I'm very thankful for that film.''

He added: "That was so cool. Dreams do come true."

Warriors head coach Steve Kerr felt Ferrell's presence would lighten the mood after such a poor run.

"He actually emailed me a while back and I didn't believe it was him," Kerr said. "So, we exchanged a couple of emails and concocted a plan.

"You know he is a huge Klay Thompson fan, and he knows how much Klay loves dressing up as Jackie Moon, so it felt like a natural fit and it felt like the time to do it, too – make everyone laugh in a tough stretch in the season and he was great.

"He came into the locker room and made the guys laugh. Everybody loved seeing him and hearing from him. He's hilarious. It was just something different."

Warriors star Stephen Curry, who passed Chris Mullin for the most steals in the franchise's history, said of Ferrell's presence: "It was fun, and I'm glad we took advantage of it.

"I think we fed off the energy. I was actually surprised, his form, he actually had some good rotation on the ball, and endless energy. I don't know how."

Kevin Durant hailed Kyrie Irving's season-high 50-point performance in the Brooklyn Nets' 132-121 win over the Charlotte Hornets as a "masterclass".

Durant took a backseat as the Nets point guard hit nine three-pointers, shooting at 79 per cent from the floor, making 15-of-19.

Irving became one of 22 players in NBA history with five 50-point games, while he also became the second guard – behind Michal Jordan – in the league to have multiple 50-point games while shooting 75 per cent or better from the floor.

"Everything he does is pure. It looked so easy tonight," Durant told reporters after the game. "I seen [sic] it in his eyes to start the game.

"He wanted to play better last game, so he came out tonight and wanted to impact the game from the start. He led us all night. It was an incredible performance.

“Younger players should watch this game and learn what it takes to score at that level. That was just a masterclass."

Nets head coach Steve Nash added to the praise of Irving, labelling him an "incredible player".

"He's incredible. He's a career-highlight reel every night," Nash said. "We have a special player on our hands. Overall, he's an incredible player and shot creator."

The result lifts Brooklyn to a 33-33 record, sitting eighth in the Eastern Conference ahead of the final push for the playoffs, having won only four of their past 21 games.

Durant added: "It's always good to get a win. We definitely want to play better than we did in the second half.

"We know we're fighting for our lives every game to get into the playoffs or the play-in. It's good to get the W."

Kyrie Irving scored a season-high 50 points to help snap the Brooklyn Nets' four-game losing run with a 132-121 victory over the Charlotte Hornets on Tuesday.

Kevin Durant took a backseat to Irving's "master class", as the Nets point guard hit nine three-pointers, shooting at 79 percent from the floor, making 15-of-19.

Irving scored 30 points in the second half, with his Nets teammates contributing 33, helping them claim their fourth win from their past 21 games.

The 29-year-old became one of 22 players in NBA history with five 50-point games, along with becoming the second guard – behind Michal Jordan - in NBA history to have multiple 50-point games while shooting 75 percent or better from the floor.

Durant added 14 points with three rebounds and seven assists while Andre Drummond had 20 points with 14 rebounds.

Giannis stars as champions win fifth straight

Giannis Antetokounmpo scored 39 points, shooting 13-of-19 including four-of-four from beyond the arc, as the Milwaukee Bucks crushed the Oklahoma City Thunder 142-115 for their fifth straight win. Khris Middleton added 25 points while Bobby Portis had 18 points with 14 rebounds.

Devin Booker was still out but the Phoenix Suns triumphed after a late Mikal Bridges block in a 102-99 win over the Orlando Magic. Deandre Ayton had 21 points with 19 rebounds for the Suns.

Ja Morant scored 24 points with eight rebounds and eight assists as the Memphis Grizzlies downed the New Orleans Pelicans 132-111, while Darius Garland became the fourth player in Cleveland Cavaliers history with 40 points and 10 assists in a game (41 and 13) as they won 127-124 over the Indiana Pacers.

Splash brothers shooting off

The Golden State Warriors' splash brothers, Stephen Curry and Klay Thompson only managed a combined three-of-15 from beyond the arc but they snapped their five-game skid with a 112-97 win over the Los Angeles Clippers. Curry and Thompson finished with 15 and 20 points respectively, while Reggie Jackson struggled with two-of-14 shooting for the Clippers.

Scotland's Duhan van der Merwe's Six Nations campaign is over after his red card for Worcester resulted in a three-game ban.

The 26-year-old was dismissed for "reckless or dangerous play" on London Irish's Kyle Rowe in Saturday's Premiership match which Worcester lost 43-12.

The suspension means van der Merwe will miss Scotland's final two Six Nations matches against Italy and Ireland.

Van der Merwe had scored his 10th try for Scotland in their 36-17 loss to France at Murrayfield Stadium on February 26.

Scotland have one win and two defeats in the Six Nations, having beaten England 20-17 in their opening game before losses to Wales and Les Bleus.

PGA Tour boss Jay Monahan has joked that Rory McIlroy has been "suspended" following comments he made calling for more transparency from the governing body.

The Northern Irishman said on Tuesday that the PGA Tour needs to be less of a "closed shop", with criticism around transparency on topics such as fines, suspensions and the vote for the player of the year.

McIlroy currently sits as one of four player directors on the Tour's policy board and prompted a sarcastic response from Monahan.

“I would just say, effective immediately, Rory McIlroy is suspended," the commissioner joked.

Monahan added: "Rory is a member of our policy board. He's a player director. That's something that has been raised in the past, and if that's something that a member of our board feels strongly about, rest assured it's a conversation we'll have with our Player Advisory Council and ultimately our board.

"That's the way the system works. It's a criticism that has been lobbied against the PGA Tour through the years, and I think we always have to be open to evolving. That's something that we are open to."

Monahan also revealed that he has not spoken to six-time major winner Phil Mickelson since facing a major backlash and taking time off from the game after comments he made about a proposed Saudi Arabia-backed Super Golf League.

Mickelson claimed the Super Golf League could provide players with "leverage" as a "once-in-a-lifetime opportunity" to "reshape how the PGA Tour operates".

Monahan said the ball was in Mickelson's court on whether he returned to the tour, although he declined to confirm if he had been suspended for his comments.

"I have not talked to Phil since he made his comments and since he said that he was stepping away. Like I said, I think the ball is in his court. I would welcome a phone call from him," Monahan said.

"But it's hard for me to talk about the different scenarios that could play out. Listen, he's a player that's won 45 times on the PGA Tour. He's had a Hall of Fame career.

"He's won here at The Players Championship. He's inspired a lot of people and helped grow this Tour, his Tour.

"So as difficult as it is to read some of the things that were said, ultimately a conversation will be had when he's ready to have it, and I will be ready to have it, as well."  

Ireland fly-half Johnny Sexton will retire after the 2023 World Cup despite signing a new deal with Irish Rugby.

The 36-year-old, who earned his 100th cap in November and won the 2018 World Player of the Year, wants to go out on a high at next year's World Cup in France.

Irish Rugby confirmed on Tuesday that Sexton had signed a new contract up until the 2023 event but the 103-cap veteran said he would finish up after that.

“Yeah, finished, 2023 World Cup – it’s up to me to work hard, get the body and mind in the best shape possible and attack the last 18 months,” he said.

“I’m still very driven to get there and perform at the World Cup. I always said that if I am enjoying my rugby and the Ireland and Leinster set-ups believe I can add value to the environment then it would be an easy decision to sign another contract.

“There is some great talent coming through at Leinster at present and I am excited about the prospect of competing at a fourth World Cup with Ireland and the potential for growth in this group between now and then.”

Sexton has played 103 times for Ireland in his storied career and reached the milestone of 500 points in the Six Nations in the 29-7 win over the defending champions last month.

A four-time European Champions Cup winner with Leinster, Sexton is now looking ahead to the prospect of a fourth World Cup finals appearance in France next year.

Brooklyn Nets head coach Steve Nash has confirmed Ben Simmons will be with the team on the bench for Thursday's return game against the Philadelphia 76ers.

Simmons is expected to receive a frosty reception from the 76ers fans at the Wells Fargo Center as he returns for the first time since last month's trade to the Nets.

The point guard had a major fallout with the 76ers after a nightmare playoffs period, leading to him requesting a trade and opting not to play all season until a trade was finalised in February.

Nash said Simmons, who is yet to debut for Brooklyn, will not play for the Nets on Thursday but will be in attendance with the team which he felt he needed to get out of the way.

"It's great," Nash told reporters prior to Tuesday's game against the Charlotte Hornets.

"He's on our team, he needs to be with his teammates and get the whole Philly thing out of the way a little bit. Maybe it never goes away, but the first time it's always nice to kind of deal with it and move on."

He added: "I don't think he's naive to think he's not going to get some boos. I hope he enjoys it. It's a part of the game I miss."

Simmons has not played since his trade due to a back complaint which has hampered his ability to get reconditioned to game standard having not played all season.

Nash was not clear-cut on Simmons' likely debut, with the Australian still not cleared to practice.

"It's to be determined," Nash said. "I think he's progressing this week, but I don't know what that means as far as Saturday.

"He'll see us [Wednesday] in Philly. I don't think he's ready for 5-on-5 basketball but he's improving, working out, and he'll join us in Philly, and a few good days of rehab."
