Elina Svitolina said playing behind closed doors at the Australian Open felt "a bit disturbing" after having fans in attendance earlier in the week.

The Ukrainian fifth seed booked her spot in the fourth round in Melbourne with a 6-4 6-0 victory over Yulia Putintseva on Saturday.

But no fans were in attendance on Margaret Court Arena as Victoria started a five-day lockdown due to coronavirus.

Svitolina, who will face Jessica Pegula in the last 16, said she felt the difference.

"It was very different conditions. I played a night match at 7:00 with a good crowd. Now it was completely different. It was for sure a bit disturbing, I would say, in some ways sad," she told a news conference.

"But it is what it is. I had to accept. I had to have a good mindset, not thinking too much about that. I just tried to focus on my game."

Svitolina reached the fourth round in Melbourne for the third time in four years after mixing 18 winners with 20 unforced errors.

But the 26-year-old said the lack of fans meant the third-round encounter felt like a practice match.

"It feels like that. I actually had few thoughts about it today. It feels like this. I tried to convince myself that it's a grand slam and that we are playing an important match. I have to focus on my match," Svitolina said.

"But for sure there's some thoughts and there is I say some low moments that can sneak into the mind. It's what we have to deal with. I'm trying my best to do it."

Novak Djokovic insists there is a real danger he may withdraw from the Australian Open, with an ultrasound on an abdominal injury planned for Saturday.

The eight-time champion at Melbourne Park pulled off a dramatic five-set win over American Taylor Fritz to reach round four, but it came at what could prove a high cost.

After battling through two tight sets to forge ahead in the match, Djokovic was jolted early in the third by a sudden "tear", as he put it.

Although painkillers allowed him to continue and fend off a Fritz comeback, the world number one might be advised by doctors that his race in Australia is run for this year.

He is due to face Milos Raonic on Sunday in round four, and the Canadian is a player that Djokovic holds an 11-0 winning career record against. This time Raonic could be gifted a walkover.

Explaining the injury blow, and what comes next, Djokovic said: "Everything was working fine for me, and then beginning of the third set I made this quick move on the return going to the forehand, rotating there, and I just felt a tear, I felt something happen.

"Went out for medical timeout when I was tested, evaluated. I have huge pain, I took the highest dose of anti-inflammatories possible.

"It did kick in end of fourth, beginning of the fifth when I actually started to move and I could actually start to rally with him from back of the court.

"Until that moment, it was only serve for me and kind of hoping and praying that I'm going to get an easy ball after my serve so I could just go for it. That's what I've done.

"I honestly don't know how I won this match. I'm very proud, at the same time sad and worried, because it's definitely something serious happening with my injury.

"I don't have much time to recover for the next match. Definitely not training tomorrow [Saturday]."

The 33-year-old Serbian would not want to risk worsening the problem, given he has plenty to play for over the rest of the year.

However, he is chasing grand slam success wherever he can get it, given he trails Roger Federer and Rafael Nadal by three on the all-time list.

Djokovic's disqualification for hitting a ball that struck a line judge at the US Open last year was followed by defeat to Nadal in the French Open final, and now his luck may be out again.

Once the tests take place on Saturday, there should be a greater sense of clarity in Djokovic's mind.

Setting the scene for what should have been a relaxed day of practice but is now a crucial day in his championship, Djokovic stressed he hoped to be able to continue.

He said of his Saturday plan: "I'm coming here to evaluate more with the doctor and medical team, and do some ultrasound and understand what's really going on so that the doctor and medical team can prescribe best possible treatment and the only possible treatment that I could even have the slightest chance to go out in less than 48 hours."

Fabien Galthie has promised France are prepared for whatever "chaos" they might encounter as they prepare to tackle Ireland in Dublin.

The thumping 50-10 win over Italy in Rome last week gave France a fast start to their Six Nations campaign, but they were always expected to win comfortably there, and taking on Ireland is a very different prospect.

Galthie has made two changes to his starting XV for Sunday's game, bringing in wing Damien Penaud and flanker Anthony Jelonch for Teddy Thomas and Dylan Cretin.

France are looking for back-to-back wins over Ireland in the Six Nations for the first time since 2010-11, having beaten them in Paris in October, but Les Bleus have lost five of the past seven encounters between the teams in the championship.

However, Galthie feels France are shaping up as an increasingly formidable force, saying: "You just have to look at the results. We won eight out of 10 matches."

The defeats in that sequence cited by Galthie came with 14 men at Murrayfield in last year's Six Nations, and in sudden death to England in the Autumn Nations Cup.

"In Scotland we lost following a red card and in London we lost in extra time. We are doing it the right way, we continue our march," Galthie said. "We will continue to make progress in many areas. We have a significant space for improvement.

"You have to be prepared for any challenge, anywhere and against anyone. You have to prepare to experience chaos with as much solidity as possible.

"This is what we prepare for without forgetting to face the unexpected."

Galthie believes Penaud may be an ideal physical fit for the task of stopping Ireland, and he said of Jelonch: "He has this ability to be tough in combat, moreover the more the intensity rises, the more he becomes dominant."

France: Brice Dulin, Damien Penaud, Arthur Vincent, Gael Fickou, Gabin Villiere, Matthieu Jalibert, Antoine Dupont; Cyril Baille, Julien Marchand, Mohamed Haouas, Bernard Le Roux, Paul Willemse, Anthony Jelonch, Charles Ollivon, Gregory Alldritt.

Replacements: Pierre Bourgarit, Hassane Kolingar, Uini Atonio, Romain Taofifenua, Dylan Cretin, Baptiste Serin, Anthony Bouthier, Teddy Thomas.

Novak Djokovic is unsure whether he will be able to play in the Australian Open fourth round after struggling with an abdominal injury in his five-set win over Taylor Fritz.

The world number one survived a huge injury scare to get past Fritz in the third round, winning 7-6 (7-1) 6-4 3-6 4-6 6-2 on Rod Laver Arena.

Eight-time Australian Open champion Djokovic appeared to injure his abdominal region during the third set.

It was a match which started on Friday in front of a crowd and finished on Saturday without fans as Victoria went into a five-day lockdown.

Fritz appeared set to reach the fourth round of a major for the first time in his career, but Djokovic suddenly came to life in the fifth set.

Next up for Djokovic is Milos Raonic, who he has beaten in all 11 of their meetings, on Sunday.

But the Serbian is concerned by his injury and was unable to commit to saying he would be able to take to the court.

"I really don't know," Djokovic said when asked for his thoughts about facing Raonic.

"Right now, I know it's a tear, definitely, of the muscle so I don't know if I'll manage to recover from that in less than two days.

"I don't know. I don't know. I don't know if I'm going to step out on the court or not.

"I am very proud of this achievement. Let's see what happens."

Djokovic felt for American Fritz after his brave defeat and discussed what he had gone through during a contest lasting three hours and 25 minutes.

He continued: "I want to congratulate Taylor for a great fight. I'm sorry that he lost the match obviously.

"I don't know. I just tried to stay in there and I was hopeful that whatever is happening there is going to feel better.

"Towards the end of the fourth it started to feel better, third and fourth set I just served and couldn't do much on the return.

"I was just going for my shots, was hitting two first serves and it worked, it worked well.

"This is definitely one of the more special wins in my life. It doesn't matter what round it is and against who it is.

"Under these kinds of circumstances, to pull this through is definitely something I'll remember forever."

Novak Djokovic survived a huge injury scare to get past Taylor Fritz in the Australian Open third round - but his title defence could be in ruins.

The world number one and eight-time champion in Melbourne edged Fritz 7-6 (7-1) 6-4 3-6 4-6 6-2 on Rod Laver Arena.

But the 17-time grand slam winner appeared to injure his abdominal region during the third set of the contest, which started on Friday in front of a crowd and finished on Saturday without fans as Victoria went into a five-day lockdown due to coronavirus concerns.

Fritz appeared set to reach the fourth round for the first time in his major career, but Djokovic suddenly came to life in the fifth set.

Next up for Djokovic is Milos Raonic, who he has beaten in all 11 of their meetings, but whether the Serbian is fit enough to play remains to be seen.

Djokovic told Eurosport he suspected he had suffered a torn muscle and that it was "in the clouds" whether he would be able to continue in the tournament.

Djokovic broke for 3-1 against Fritz and crucially dug himself out of a 15-40 hole in the seventh game, but a forehand into the net saw him fail to serve out the set.

Yet Djokovic was close to flawless in the tie-break, winning the first six points before closing it out, and then breaking to begin the second set.

That spurred Djokovic to win the second before the drama followed.

He took a medical timeout after the third game of the third set and then repeatedly required treatment on his abdominal region.

The injury seemed to be bothering Djokovic, who was broken after sending a forehand long in the eighth game, and Fritz closed out the set.

A struggling Djokovic was broken again in the third game of the fourth set before fans were forced to leave Rod Laver Arena ahead of restrictions being introduced in Victoria, but Fritz levelled the match.

Djokovic looked far healthier to begin the final set and he broke for 4-2 with a brilliant forehand winner after a baseline exchange, winning four straight games on his way to a post-midnight victory.

Ireland will be without Johnny Sexton for Sunday's visit of France in the Six Nations after their captain suffered a blow to the head against Wales. 

Sexton underwent return-to-play protocols after the incident in the loss but has not been cleared to play. 

The news comes after Sexton hit out at a French doctor who claimed the fly-half had suffered approximately 30 concussions in his career, with neurologist Dr Jean-Francois Chermann subsequently apologising. 

Billy Burns will start instead for Andy Farrell's side, who lost 21-16 in Cardiff, with Jamison Gibson-Park also in the XV as scrum-half Conor Murray sits it out with a hamstring injury. 

The captain's armband goes to Iain Henderson for the first time, with the suspended Peter O'Mahony replaced by Rhys Ruddock following his red card in the Welsh capital. 

James Ryan also sustained a blow to the head in that game and, like Sexton, will be absent this weekend.

Ireland: Hugo Keenan; Keith Earls, Garry Ringrose, Robbie Henshaw, James Lowe; Billy Burns, Jamison Gibson-Park; Cian Healy, Rob Herring, Andrew Porter; Tadhg Beirne, Iain Henderson; Rhys Ruddock, Josh Van der Flier, CJ Stander.

Replacements: Ronan Kelleher, Ed Byrne, Tadhg Furlong, Ultan Dillane, Will Connors, Craig Casey, Ross Byrne, Jordan Larmour.

Naomi Osaka and Garbine Muguruza set up a blockbuster clash at the Australian Open, while Aryna Sabalenka cannot wait to face Serena Williams.

As Williams was tested before winning through, Osaka and Muguruza raced through their third-round outings in Melbourne on Friday.

Osaka and Muguruza dropped just seven games between them to set up what will be their first meeting, which will take place without fans in attendance as Victoria prepares to move into a five-day lockdown beginning on Saturday due to coronavirus concerns.

Sabalenka also progressed and will next face Williams, while Simona Halep cruised through.

OSAKA, MUGURUZA STORM THROUGH

Osaka, the three-time grand slam champion, brushed past fellow seed Ons Jabeur 6-3 6-2 in the third round.

The Japanese star, winner of the Australian Open in 2019, is looking forward to facing fellow major champion Muguruza.

"I've practised with her once, but it was on grass, and I was younger. It was maybe like a couple years ago," Osaka said.

"But I just remember being really impressed by her, and for me, I've watched her win Wimbledon and win the French Open when I was younger, and I've always wanted to have the chance to play her. So for me, this is really exciting."

A finalist at the Yarra Valley Classic last week, Muguruza's strong start to the Australian Open continued with a 6-1 6-1 thrashing of Zarina Diyas.

"I don't think we've played each other before. Just looking forward for a fourth round, a good fourth round, playing the top players," Muguruza – who has lost just 10 games in the first three rounds – said ahead of facing Osaka. "I feel like that's always the right way, you know, a good sign. Just expecting a good match."

JOB DONE FOR SERENA

Williams' bid for a record-equalling 24th grand slam singles title remains on track after overcoming Russian teenager Anastasia Potapova 7-6 (7-5) 6-2.

In her 101st Australian Open match, Williams secured her 90th career victory in Melbourne. The 39-year-old also improved her overall slam record to 360-51 – Martina Navratilova (306-49) is the only other player to pass 300 wins in the Open Era.

Next up for Williams is Sabalenka, who was too good for Ann Li, winning 6-3 6-1 to reach a major fourth round for just the second time in her career and first in Melbourne.

The Belarusian seventh seed is not daunted by the task facing her when she meets the American for the first time.

"I want to get this thrill. Can I say thrill? I said it right. So it's going to be a thrill. But, yeah. I'm going to do everything I can," Sabalenka said.

HALEP THROUGH AS SEEDS CRUISE

Halep reached the fourth round in Melbourne for the sixth time with a convincing 6-1 6-3 win over Russian 32nd seed Veronika Kudermetova.

Awaiting the two-time major winner in the fourth round is Iga Swiatek after the Polish 15th seed got past Fiona Ferro 6-4 6-3.

Swiatek thrashed Halep 6-1 6-2 on her way to the French Open title last year.

Marketa Vondrousova, the 2019 French Open runner-up, reached the fourth round of the Australian Open for the first time after beating Sorana Cirstea 6-2 6-4.

Up next for the Czech 19th seed is Hsieh Su-wei, who battled past Sara Errani 6-4 2-6 7-5 after two hours and 44 minutes.

Errani had won her previous three meetings with Hsieh in straight sets, including winning a set 6-0 - known as a 'bagel' in tennis parlance - in each of those victories.

It meant Hsieh, 35, had a simple plan against the Italian.

"I don't remember when I lose to someone but someone reminded me I eat the bagel every time so I said, 'Okay, I will try to not take any bagel today'," she said.

Fans were forced to leave Rod Laver Arena with Novak Djokovic's third-round match at the Australian Open still in progress. 

With Victoria entering a five-day lockdown from Saturday due to coronavirus concerns, spectators were told to leave Melbourne Park before 23:30 local time (12:30 GMT). 

Restrictions were coming into place in Victoria from 23:59 local time (12:59 GMT). 

Djokovic's clash against Taylor Fritz was the only match still in progress, although fans were informed to leave amid increasing drama. The world number one led by two sets to one but was struggling with a suspected abdominal injury in the fourth. 

There were boos when the announcement was made, with a message also displayed inside the arena. Play was briefly suspended as fans were moved out. 

No spectators will be allowed at the year's first grand slam for the next five days, although the tournament will continue. 

Dominic Thiem came from behind to edge Nick Kyrgios in a five-set epic in the Australian Open third round on Friday.

Thiem, last year's runner-up in Melbourne, fought back to win 4-6 4-6 6-3 6-4 6-4 on John Cain Arena.

The Austrian third seed was unable to match Kyrgios' energy levels early on, but the reigning US Open champion responded to reach the fourth round of a major for the 15th time in his career.

Thiem, who will face Grigor Dimitrov in the fourth round, was in impressive form after his slow start, finishing with 57 winners and just 28 unforced errors.

Kyrgios was getting the crowd – full of energy ahead of Victoria going into a five-day lockdown from Saturday due to coronavirus concerns – involved from the warm-up, while Thiem appeared flat.

An underarm ace saw Kyrgios take a two-sets-to-love lead as he looked in control before Thiem responded.

Coming from 15-40 down in the opening game of the third set, Thiem won 20 consecutive points on serve.

Kyrgios steadied and held after a marathon game to begin the fourth set, but he could not deny Thiem – who continued to hold serve comfortably – in the ninth as the Austrian broke with a cross-court forehand pass.

A point penalty for ball abuse appeared to bring Kyrgios to life, but Thiem saved a break point and served out the set.

The crucial and only break of the fifth set came for Thiem in the seventh game after several fine returns and he closed out his victory with a spectacular backhand winner down the line.

Fernando Alonso had surgery on a jaw fracture after a road accident while cycling but is expected to be fit for the start of the 2021 Formula One season.

There were initially doubts the two-time F1 champion would be ready to make his return to the series after a two-year absence at the season-opening Bahrain Grand Prix on March 28 following the incident in Switzerland on Thursday.

Alonso underwent an operation on his jaw and is expected to remain in hospital until Sunday at the earliest.

However, Alpine have confirmed they do not expect the injury to have any impact on their preparation for the new campaign, with pre-season testing scheduled to take place at Sakhir from March 12-14.

"Following his cycling accident yesterday Fernando Alonso was kept under observation in hospital in Switzerland," read an Alpine statement issued on Friday.

"Medics discovered a fracture in his upper jaw and conducted a successful corrective operation. The attending medical team are satisfied with his progress.

"Fernando will remain under observation in hospital for a further 48 hours.

"Looking forward, after a few days of complete rest, he will be able to progressively resume training. We expect him be fully operational to undertake preparation for the season.

"Alpine F1 Team and Fernando thank you for your wishes and will issue further updates when appropriate."

Stephen Curry believes he is experiencing one of the best moments in his career and plans to let his game do the talking as the MVP conversation heats up.

The Golden State Warriors improved to 14-12 thanks to a 111-105 victory over the Orlando Magic, with Curry contributing 10 three-pointers in a 40-point haul. He also had eight rebounds, five assists and four steals.

It extended Curry's career-best streak of making at least four three-pointers to 13 games and was the 17th time he has reached double digits for makes from beyond the arc – no player in NBA history has more than five such games.

Curry acknowledged that the Warriors' win-loss record could have a negative impact on his chances of being named MVP, but he wants to solely remain focused on prolonging his impressive form.

"The game speaks for itself – 15-16, 14-15, those two years is the exact same kind of conversation," said Curry.

"Obviously, that's an amazing accomplishment, and being in that conversation with all that we've been through in the last two or three years, that means something.

"Those narratives make themselves as you go through the season and my job is to be at the level I expect to be and usually that means you're at the top of the end of the season.

"I really try not to get distracted by that because it kind of taints the moment. If I do my job, I'll be there at the end of the season."

Asked if Curry should be in the MVP conversation, Warriors coach Steve Kerr replied: "How could he not be? He's other-worldly."

He added on Curry's latest display: "It is routine, which is the crazy part of it. You just come to expect it.

"These threes that he hits when there's nothing there offensively and he just uses his dribble to free himself up, not exactly with a ton of space just a few inches of space, then he rises up and you expect every single one of them to go in, it's kind of crazy. He's in a really good groove."

Two-time MVP Curry has scored at least 30 points in four straight games and will match the best run of his career if he extends that streak to five against the Brooklyn Nets on Saturday.

While not looking to compare parts of his career, Curry acknowledged he is experiencing one of his best stretches in the NBA.

"One hundred per cent, but it's all about what's happening now. I don't compare it to what's happened in the past," said Curry.

"I obviously know the levels I've been at and our team's been at and where we're trying to go as a team, but definitely in terms of how I'm playing – I've been saying it for a while – I feel confident and strong and in rhythm. It's a good feeling and I want to keep getting better, that's the goal."

Buoyant Scotland will go in search of back-to-back wins over Wales for the first time in 18 years and France travel to Ireland for a mouthwatering Six Nations showdown this weekend.

Scotland ended a 38-year wait for a win at Twickenham on the opening weekend with a dominant 11-6 defeat of the defending champions.

Gregor Townsend's side need to follow that up on Saturday with a victory over a Wales side that got the better of 14-man Ireland at the Principality Stadium following Peter O'Mahony's first-half red card.

France started the tournament by hammering Italy 50-10, but will face a bigger test in Dublin, while England should respond to their Calcutta Cup defeat by beating Italy at home on Saturday.

Ahead of the second round, we preview the upcoming matches with help from Opta.

ENGLAND v ITALY

FORM

The Red Rose have won each of their 21 fixtures against Italy in the Six Nations, and they are the only team yet to suffer defeat against the Azzurri in the championship.

England have hosted Italy on 10 occasions in the Six Nations, winning each of those 10 fixtures by an average margin of 31 points and scoring 5.6 tries per game.

Italy have won just twice away from home in the Six Nations (losing 50 and drawing one), with both victories coming against Scotland at Murrayfield (2007 and 2015).

ONES TO WATCH

George Ford comes into the England side, with captain Owen Farrell moving to outside centre, in one of five changes to the side, and the fly-half will be ready to make a statement after being named on the bench for the loss to Scotland.

Italy endured a torrid start to the competition, but Luca Sperandio scored a fine try. The wing had seven carries and made 52 metres. The Azzurri will need to get Sperandio flying down the flank again in London.

SCOTLAND v WALES

FORM

Scotland were superb against England and will be aiming for consecutive wins over Wales in the Six Nations for the first time since 2002-2003.

Wales had an extra man, but Ireland could consider themselves unfortunate to go down 21-16 in Cardiff. The Welsh have lost their last six Tests away from home and will be in for another huge battle at Murrayfield.

They have conceded 30 points per game in that miserable sequence of matches on their travels.

ONES TO WATCH

Captain Stuart Hogg was man of the match in a rousing performance from Scotland against Eddie Jones' men. The full-back made 112 metres and had 13 carries. He was also brilliant with the boot, kicking for 367 metres.

Louis Rees-Zammit showed why he is so highly rated in Wales' win over Ireland. He dived to finish magnificently in the corner as Wayne Pivac's side made a winning start at home last Sunday.

IRELAND v FRANCE

FORM

Flanker O'Mahony's reckless dismissal proved to be costly for Andy Farrell's Ireland side in Cardiff. They will be looking to avoid suffer back-to-back losses to Les Bleus in the Six Nations, having not endured such a fate since 2010-11.

Ireland have won five of their last seven clashes with France in the Six Nations (L2) after winning only four of their 30 previous meetings with them in the Five/Six Nations (D3 L23).

ONES TO WATCH

Antoine Dupont was the player of the opening round of the tournament. The mercurial scrum-half assisted four tries, the joint-most by any player in a Six Nations match, equalling the record set by Frederic Michalak against Italy in 2006. He also scored a try of his own in a sublime performance.

Ireland lock Tadhg Beirne made the most carries (21) of any player in the opening round. He also hit the most rucks of any player (48) and was Ireland’s joint-highest tackler (10, level with CJ Stander).
