France prop Mohamed Haouas and wing Gabin Villiere have followed scrum-half Antoine Dupont and coach Fabien Galthie in testing positive for coronavirus.

The Six Nations leaders, who have won two games from two in this year's tournament, are struggling to contain a COVID-19 outbreak in their camp.

Dupont, Galthie, forwards coach William Servat and another staff member returned positive tests earlier this week.

Following another round of testing, the French Rugby Federation (FFR) announced on its website on Saturday that Haouas and Villiere have also contracted the disease.

France's health minister Olivier Veran said on Thursday that anyone testing positive would now need to self-isolate for 10 days, instead of the previous seven.

All members of Les Blues' squad will be tested again on Sunday, the same day that a new 31-man training squad is to be named for next week's clash with Scotland in Paris.

Haouas, Villiere and Dupont started France's victories over Italy and Ireland, with the latter named player of the round in the opening set of fixtures.

Naomi Osaka has set her sights on a fifth grand slam trophy after winning the Australian Open.

Osaka added a fourth major title to her collection thanks to Saturday's 6-4 6-3 victory over 22nd seed Jennifer Brady in Melbourne.

Former world number one Osaka became the first woman since Monica Seles in the early 1990s to emerge victorious from the first four grand slam finals of her career, having boasted a perfect 3-0 record following success at the US Open (2018 and 2020) and Australian Open (2019).

Osaka has been tipped to dominate the WTA Tour and celebrate further major success, but the Japanese star and third seed is not looking too far into the future.

"I'm taking it in sections," Osaka, who reeled off six successive games from 4-4 in the first set against Brady to take control, said during her post-match news conference.

"For right now, I'm trying to go for five. You know, after five I would think about maybe dividing the 10, so maybe seven or eight.

"I like to take things not big-picture. For me, I like to live in the moment. It's an honour that he [Mats Wilander] said that [I would get a minimum of 10], of course.

"But I don't want to weigh myself down with pressure and expectations. I know that the people that I'm playing against are the best players in the world and, if my time comes to win another Grand Slam, it will come.

"But for right now I can only control what I can control, and that's working hard and giving myself opportunities."

Osaka - who fended off a pair of match points against Garbine Muguruza in the last 16 at Melbourne Park - also became the seventh woman to have won the Australian Open after saving match point, following in the footsteps of Seles (1991), Jennifer Capriati (2002), Serena Williams (2003 and 2005), Li Na (2014), Angelique Kerber (2016) and Caroline Wozniacki (2018).

The 23-year-old won in 77 minutes to become the 12th woman in the Open Era to clinch multiple Australian Open titles. 

Osaka has now gone 21 matches without defeat - she is only the third woman since 2010 to enjoy an unbeaten streak of 20 or more matches, joining Serena (27 wins between 2014 WTA Finals and 2015 Madrid) and Azarenka (26 wins between 2012 Sydney and Miami).

Asked about her perfect record in slam finals, Osaka added: "I feel like for me I'm not sure if it's something you're born with.

"But I know that I didn't play a lot of tournaments when I was a kid, so I'd always want to take the opportunity whenever someone was watching me, I'd feel like it was more fun that way.

"So maybe that's how I developed wanting a crowd and wanting to play in front of more people.

"I also think it's because I watched a lot of grand slams growing up and seeing the crowds, seeing Arthur Ashe Stadium, seeing how it was in Australia and Rod Laver, and wanting to play in front of people and wanting to be the person holding up the trophy."

Following in the footsteps of Seles and 20-time slam champion Roger Federer as the only three players to have won their first four major deciders, Osaka said: "That's very amazing company. I hope that I can have one grain of how their career has unfolded.

"You can only wish and you can only just keep going down your own path. But, yeah, it's definitely something crazy to hear."

Dan Carter was hailed as "one of the best to have ever played the game" who has "amazed for almost two decades" after the New Zealand legend announced his retirement.

Mercurial fly-half Carter confirmed on Saturday that his incredible career is over at the age of 38.

The All Blacks great won the Rugby World Cup twice and is the record points-scorer in Tests with 1,598, while he was named World Rugby Player of the Year a joint-record three times.

Carter claimed three Super Rugby titles with the Crusaders, while he also won honours with Perpignan, Racing 92 and Kobelco Steelers.

He tweeted: "I officially retire from professional rugby today. A sport I've played 32 years which has helped shape me into the person I am today.

"I can't thank everyone who has played a part in my journey enough, particularly you, the fans. Rugby will always be a part of my life. Thank you."

The All Blacks paid tribute to Carter on social media, posting: "Thank you @dancarter_. You have amazed us for almost two decades with your deeds on the field.

"Now it's time to put your feet up and enjoy the next chapter. #Icon."

The world governing body also expressed its gratitude to the number 10.

A post from the World Rugby account said: "A two-times @rugbyworldcup winner and one of the best to have ever played the game. Thank you for everything you have given to our sport, @DanCarter."

Former South Africa wing Bryan Habana simply wrote: "Congrats on an incredible career @DanCarter !!"

A tweet from the Springboks account read: "Congratulations on a stellar career @DanCarter and good luck with the next chapter. You'll always be welcome for a braai here in South Africa!"

Former referee Nigel Owens posted: "You will be remembered as one of the greatest ever, but more importantly, not just on the field but off it as well.

"A true gentleman. It was always a pleasure and privilege. Best wishes for the future."

Jennifer Brady feels winning a grand slam is "totally achievable" and within reach after falling to Naomi Osaka in the Australian Open final.

Brady had her first taste of a slam final on Saturday but the American 22nd seed was outclassed by four-time major champion Osaka 6-4 6-3 in Melbourne.

The 25-year-old was the seventh woman in the past nine majors to appear in a maiden final. Iga Swiatek (2020 French Open), Sofia Kenin (2020 Australian Open), Bianca Andreescu (2019 US Open), Ash Barty (2019 French Open) and Osaka (2018 US Open) all tasted success, while Marketa Vondrousova (2019 French Open) and Brady were the only two to suffer defeat.

Reflecting on the result on Rod Laver Arena, Brady told reporters: "I think I belong at this level. I think winning a grand slam is totally achievable. It's within reach.

"Playing out there, obviously I was nervous, didn't go my way, but at the same time coming off court, I was, like, okay, that feels a little bit normal. 

"It felt different than what I was expecting it to feel like. If you were to ask me maybe a year ago, I wouldn't think it's possible or it would feel like it's, like, going to Mars.

"So, I would say just being more comfortable at this level."

Brady added: "I have mixed feelings. I'm pretty proud of myself, my team, for what we achieved here. We came here, you know, and I reached my first grand slam final. 

"But also, I'm walking away with the runner-up trophy, not the winner's trophy, so that's a little bit sad.

"I would say I'm pretty happy with my performance over the past couple weeks."

"I know that everyone was cheering for [Serena Williams] and I'm sorry it had to end like this. I want to say thank you for watching the match."

Naomi Osaka's first grand slam title was memorable for all the wrong reasons - the Japanese left in tears after defeating her idol Serena Williams in the 2018 US Open final.

Williams was penalised for receiving coaching, slamming her racquet and then arguing with the chair umpire, which cost the 23-time slam champion a game in the second set.

The mood on Arthur Ashe Stadium turned bitter as fans booed during the trophy ceremony.

"I just felt like everyone was sort of unhappy up there," Osaka told the 'Today' show a day after the final. "I know that it wasn't really – the ending wasn't how people wanted it to be. I know that in my dreams I won in a very tough, competitive match. I don't know. I just felt very emotional. I felt like I had to apologise.

"I felt a little bit sad, because I wasn't really sure if they were booing at me or if it wasn't the outcome that they wanted. I also could sympathise, because I've been a fan of Serena my whole life, and I knew how badly the crowd wanted her to win."

Almost three years on and three further slam titles later, that softly-spoken Osaka is now a ruthless machine, just ask Williams.

En route to a fourth slam crown and second Australian Open trophy on Saturday, Osaka overpowered the 23-time major champion in the semi-finals, stopping her ongoing record-equalling quest flat in its tracks.

The queen of women's tennis for so long, Williams could not find a way to beat Osaka.

The here and now, Osaka continues to be Williams' kryptonite in the American superstar's bid match Margaret Court. It could explain why Serena was left in tears and cut short her post-match news conference.

There appears to be no way past Osaka.

Usually timid away from the action, Osaka is ferocious on court but just as calm - her triumphant 2021 Australian Open campaign further proof of that, having saved a pair of match points in the last 16 before topping Jennifer Brady on Rod Laver Arena, where she became the first woman since Monica Seles in the early 1990s to emerge victorious from the first four grand slam finals of her career. 

Lets not forget her anti-racism statements during the last year's US Open. The 23-year-old regularly wore masks onto court to protest against racial injustice in the United States. Osaka's off-court impact is just as powerful across the globe.

As the sun begins to fade on the career of an all-time great, Osaka has the world at her feet in an exciting new era for women's tennis.

New Zealand great Dan Carter has announced his retirement from rugby at the age of 38.

The fly-half won two World Cups with the All Blacks and holds the record for the most Test points scored with 1,598, ahead of Jonny Wilkinson on 1,246.

The former Crusaders star, who also played for Perpignan and Racing 92 in France, has been playing for Kobelco Steelers in Japan and also turned out for the Blues in his homeland last year.

"I've thought about this on so many occasions but today is the day and I am very grateful that I can do it on my terms," Carter wrote on Instagram on Saturday.

"I'm officially retiring from professional rugby. A sport I've played for 32 years which has helped shape me into the person I am today.

"I can't thank everyone who has played a part in my journey enough – from my team-mates, opponents, coaching and management teams, sponsors and in particular you, the fans.

"A special mention to my friends and family who have supported and guided me through my career. Mum and Dad, thank you for everything you have sacrificed for me. My wife Honor for being my rock and allowing me to fulfil my dreams while raising our beautiful family – I can't thank you enough.

"I'm excited about my next chapter in life and what that will look like. For now, I'm sad to walk away from playing but the timing is right. Rugby will always be a part of my life. Thank you."

Speaking to the New Zealand Herald, Carter said "I knew in my mind the time was right" as the coronavirus pandemic made him consider whether he should keep playing abroad away from his family, with his fourth child on the way.

"After experiencing rugby in Japan I thought I could squeeze a few more years out of my body," he said. "There was something really enjoyable about being part of that environment and the culture we had at the Kobe Steelers. I was playing rugby and enjoying it and wasn't sure when I would stop.

"I got forced back by COVID in March and was gutted about that. I was coming off contract and I guess the frustrations of not being able to finish the Japanese season and then going to the Blues for a little bit, I loved that. I loved being part of the team environment but going through that process it made me realise that I play to be the best player out on the field.

"That is my drive and it always has been and I just didn't have that drive back here in New Zealand. When I realised the age my kids are and the amount of work Honor [Carter's wife] was doing looking after them while I was away chasing my dream, it made me realise it was time to stop."

Carter won three Super Rugby titles with the Crusaders and remains the leading scorer in the competition.

He won 112 caps for New Zealand, lifting the 2011 World Cup, although he missed much of the tournament due to a groin injury. He then led the All Blacks to defend their crown four years later with a man-of-the-match display in the final against Australia.

Former England coach Clive Woodward described Carter's performance against the British and Irish Lions in a Wellington Test in 2005 as "off the Richter scale" and "possibly the best individual performance I have ever witnessed at Test level".

An elated Naomi Osaka described playing a grand slam amid the health pandemic as a "super privilege" after outclassing Jennifer Brady to win the Australian Open for a second time.

The Japanese third seed completed a 6-4 6-3 triumph on Rod Laver Arena to become the first woman since Monica Seles in the early 1990s to emerge victorious from the first four grand slam finals of her career, having boasted a perfect 3-0 record following success at the US Open (2018 and 2020) and Australian Open (2019).

Osaka's latest two triumphs in New York and now Melbourne have come amid the coronavirus pandemic, although fans were in attendance for this victory.

The 23-year-old paid tribute to her beaten opponent, who she also defeated at Flushing Meadows, while revelling in another slam success.

"We played in the semis at the US Open a couple of months ago. I told everyone who would listen that you were going to be a problem, and I was right," Osaka said at the post-match presentation.

"My team is like my family so I'm sure you guys will have a lot of adventures together. I know your friends and your family are very proud of you and we're going to play a lot more matches, so get used to that!

"It feels really incredible for me. Just to have this energy [from fans], it really means a lot. Thank you so much for coming.

"Thank you for opening your hearts and your arms towards us. Playing a grand slam right now is a super privilege and I don't take this for granted."

Brady, seeded 22nd, was playing in the first slam final of her career against Osaka, and labelled the former world number one an "inspiration" to every player on the tour.

"Firstly I'd like to congratulate Naomi. She's such an inspiration to us all and what she's doing for the game is amazing. I hope young girls at home are watching are inspired by what she's doing," Brady said.

"I'd like to congratulate her team. You're obviously doing something special and she's getting better every day.

"I'd like to say thanks to my team. Without you guys I wouldn't be standing here tonight. Thank you for everything you've done for me and let's keep going for more.

"Mom, I know you're watching right now in front of the TV, probably crying, so... it was special to play in front of fans. Tonight, it wasn't meant to be, but hopefully there's many more."

Tyronn Lue relished seeing Kawhi Leonard and Paul George return from injury as the Los Angeles Clippers impressively beat the Utah Jazz.

The Jazz had won nine straight games and 20 of their last 21 NBA contests coming into Friday's game.

However, their streak came to an end as the Clippers emerged triumphant 116-112 in a battle between two championship contenders.

Leonard led the way for the home Clippers with 29 points as they improved to 22-9.

Donovan Mitchell had a game-high 35 points, but the Western Conference leading Jazz fell to 24-6.

Leonard had missed the previous three games with a lower leg contusion, while George was back after seven games out with a swollen toe.

The win came two days after the Clippers had lost by 18 to the Jazz playing without Leonard, George and Nicolas Batum.

"They are the best team in the NBA right now, record-wise, we knew that they won 20 of 21 coming into it – we understood that," Lue said after the win. 

"We got our guys back and we wanted to win this game and the guys went out and did a hell of a job.

"Our defense was pretty good until the heroics of Donovan Mitchell down the stretch.

"Pat Beverley and PG, we did a decent job on that first half and second half, he [Mitchell] got going, that's what great players do. 

"Overall, defensively, I thought we were pretty good like I said until the last 40 seconds or whatever it was of the game."

George had 15 points, six rebounds and five assists in 27 minutes.

"I wasn't ready to play 30-plus," he said. "Got to get back to that basketball conditioning.

"I probably would have hurt the team if I'd been on the floor past the minutes I was."

The Jazz were outrebounded 45-38, leaving Mitchell and Rudy Gobert clear where the game was lost.

"We lost the game on the boards," said Mitchell. "It was second-chance points that really hurt us. 

"If you look at the overall game, we played solid defense throughout, but they just came out there and got the extra boards and rebounds and we just got to do a better job of that.

"This is a bump in the road and a good one."

Gobert feels the loss will ultimately benefit the Jazz.

He said: "If we get those rebounds, we win this game. [The Clippers are] a very good team.

"They came out rested, they came out ready and it felt like a playoff game – the intensity, the tough shots that they were making all night. 

"It was a good opportunity for us to just keep getting better."

Daniil Medvedev goes into Sunday's Australian Open final against Novak Djokovic in incredible form.

The Russian star extended his winning streak to 20 matches with a straight-sets victory over Stefanos Tsitsipas in the semi-finals on Friday.

Medvedev became the 25th man in the Open Era to record a Tour-level winning streak of 20 matches. He is the sixth active player to manage the feat, joining Djokovic, Roger Federer, Rafael Nadal, Andy Murray and Juan Martin del Potro.

The 25-year-old's run has not only been utterly dominant, but also included some rather impressive wins.

Of his 20 victories, 12 have come against top-10 players, including Djokovic. Since November, Medvedev has beaten every other member of the top 10 except Federer, who has been out of action.

"It's great to know this. It's a pity that Roger is not playing. I would love to have played him. I'm not saying anything. I just would love to play against him. I mean, to play against Roger is always a privilege. Against Novak, Rafa, Roger," Medvedev said after his win over Tsitsipas.

"But it's great to hear this. I mean, happy about myself, because I remember one moment when I was already playing quite good I actually was struggling with the top-10 guys when I was maybe around top 20 or top 30.

"It's great to hear this and I'm really happy about it."

Along with Djokovic and Nadal, Medvedev's run has also included wins over Dominic Thiem, Alexander Zverev (three times), Andrey Rublev, Matteo Berrettini and Tsitsipas.

In his 20-match streak, Medvedev has won 44 sets and lost just seven, and two of those were in his five-set victory over Filip Krajinovic in the third round.

Medvedev has won three of his past four meetings with Djokovic, who edges their overall head-to-head 4-3.

His run will have Medvedev full of confidence as he bids to win a first grand slam title, needing to overcome the record eight-time champion in Melbourne to do so.

Denver Nuggets head coach Michael Malone described the efficiency of Jamal Murray's 50-point haul as "remarkable".

Murray went 21-of-25 from the field and eight-of-10 from three-point range to post 50 points in the Nuggets' 120-103 win over the Cleveland Cavaliers on Friday.

Malone lauded the guard's performance after the Nuggets improved their record to 16-13.

"I've been around a lot of great players, I've been in the league for a long time, I've seen many 50-point games," he said.

"To do it as efficiently as he did is really remarkable."

Nikola Jokic finished with a triple-double of 16 points, 12 rebounds and 10 assists for the Nuggets.

Murray said the Nuggets' numerous threats made his life easier against the Cavaliers.

"I can shoot a little bit. Once I see a few go down, I just took off from there and kind of mixed it up," he told Altitude TV.

"I was able to get to the rim on them when they tried to change the coverage and we've got a lot of weapons. You can't just flat-out double me when I'm hot, you've got a 'Joker' [Jokic], who's MVP of the season, he'll pick you apart if you're playing four on three especially.

"I feel like it was just a tough task to be able to deal with both of us and the rest of the team as well."

The Los Angeles Clippers ended the Utah Jazz's winning run in the NBA on Friday, while Joel Embiid and Jamal Murray posted 50-point games.

The Clippers snapped the Jazz's nine-game winning streak with a 116-112 victory in a clash between two NBA championship contenders.

Kawhi Leonard led the way for the Clippers with 29 points as they improved to 22-9.

Donovan Mitchell had a game-high 35 points, but the Jazz's winning run came to an end, with the Western Conference leaders now 24-6 this season.

Embiid's career-high 50 points, 17 rebounds and five assists helped the Philadelphia 76ers past the Chicago Bulls 112-105.

He is the first 76ers player to score 50-plus points since Allen Iverson in 2005.

Murray, meanwhile, was spectacular in the Denver Nuggets' 120-103 victory over the Cleveland Cavaliers.

The guard was an incredible 21-of-25 from the field, and eight-of-10 from three-point range, for his 50-point haul.

Murray and Embiid were the first NBA pair with 50-plus points on 65 per cent-plus shooting on the same day since Tom Chambers and Patrick Ewing on March 24, 1990, as per Stats Perform.

Nikola Jokic had a triple-double of 16 points, 12 rebounds and 10 assists in the Nuggets' win.

Giannis leads Bucks, Curry's Warriors fall short

Giannis Antetokounmpo's double-double of 29 points and 19 rebounds saw the Milwaukee Bucks past the Oklahoma City Thunder 98-85.

Stephen Curry had 29 points, 11 assists and seven rebounds, but the Golden State Warriors were beaten by the Orlando Magic 124-120.

Magic star Nikola Vucevic finished with a triple-double of 30 points, 16 rebounds and 10 assists.

Despite a double-double from Trae Young (31 points and 11 assists), the Atlanta Hawks went down to the Boston Celtics 121-109.

Wayward VanVleet

Fred VanVleet went four-of-20 from the field for just 12 points in 37 minutes, but the Toronto Raptors still got past the Minnesota Timberwolves 86-81.

Edwards' incredible dunk

Anthony Edwards was three-of-14 from the field for just seven points in 34 minutes in the Timberwolves' loss, yet the 2020 top draft pick produced a monstrous dunk.

Friday's results

Orlando Magic 124-120 Golden State Warriors
Denver Nuggets 120-103 Cleveland Cavaliers
Boston Celtics 121-109 Atlanta Hawks
Philadelphia 76ers 112-105 Chicago Bulls
Phoenix Suns 132-114 New Orleans Pelicans

Heat at Lakers

The Los Angeles Lakers (22-8) look to bounce back from their loss to the Brooklyn Nets when they host the Miami Heat (12-17) on Saturday in what is a rematch of last year's NBA Finals.

Novak Djokovic will take the advantage of having an extra day's rest into the Australian Open final against the red-hot Daniil Medvedev.

Djokovic is set to compete in his 28th grand slam final and ninth in Melbourne as the Serbian star eyes an 18th major title on Sunday.

The 33-year-old looked in good form in a semi-final thrashing of Aslan Karatsev on Thursday – 24 hours before Medvedev impressively dispatched of Stefanos Tsitsipas.

For the second year in a row, Djokovic will have an extra day's rest over his opponent ahead of the decider.

Since 2000, players who have had the extra day's rest have won 12 and lost nine of the 21 finals. Djokovic has had the slight advantage four times – and four times he has not – and won all eight finals.

Given he has battled a suspected abdominal injury at this year's tournament, the additional day could be an important factor for Djokovic.

He faces Medvedev, who is on a 20-match winning streak that has included 12 victories over top-10 players.

The latest of those was a 6-4 6-2 7-5 mauling of Tsitsipas in their semi-final on Friday.

A key for Medvedev in that success, in which he endured a third-set blip, was that it came in two hours, nine minutes.

Since 2000, men who won the second semi-final in less than three hours are 6-5 in deciders. That record drops to 3-7 when the last-four clash has exceeded three hours.

Of the three that have managed it after marathon wins, Djokovic achieved it twice – in 2012 and 2015, while Rafael Nadal was the other in 2009, when he beat Roger Federer in the final after winning an epic against Fernando Verdasco.

It leaves the extra day's rest likely to be less of a factor on Sunday as both men chase history.
