Rory McIlroy and Collin Morikawa faced an overnight wait to learn whether they had made the cut at the windswept Abu Dhabi Championship, as Scott Jamieson clung to first place.

McIlroy made a vital birdie at the par-five 18th to improve his score to three over, having dropped four shots over the previous five holes.

His opening 72 had been way off the pace, and a 75 in the gusting wind could be considered a better result, nudging the four-time major winner up 15 places to a share of 60th position at Yas Links.

Reigning Open champion Morikawa added a 74 to his opening 73 to sit alongside McIlroy, both men hoping there was no surge coming from those left with holes still to play in the second round.

Play was suspended amid fading light on Friday, after the high winds made scoring treacherously difficult.

Jamieson had opened with a 63 on Thursday, but he had two bogeys and a double in his second round, which he started from the 10th tee. Birdies at 11 and eight kept the 38-year-old Scot just ahead of the field after a 74, with Viktor Hovland, Ian Poulter and James Morrison all one shot back.

Hovland also shot a 74, Poulter impressed with a 72, while Morrison, level par for the day, had four holes of his round to complete as darkness fell.

Former Open champion Shane Lowry was in a group of four on five under, while Denmark's Jeff Winther was the only player to break 70, his round of 69 featuring five birdies and taking him to four under, in a share of ninth.

In the first DP World Tour event of the year, the drastic change in playing conditions provided a stiff test for all, some former Masters winner Danny Willett was among those who struggled.

His 80, after an opening 72, meant the Yorkshireman could be definitely confirmed as missing the cut on eight over. Only four players scored worse.

The top 65 players and ties are assured of playing the final two rounds, with the second round to resume at 07:30 local time on Saturday (03:30 GMT).

Jamieson, the world number 336, said it "certainly wasn't easy" for the players who had enjoyed conditions suitable for low-scoring on the opening day.

"It's so tricky," he said, quoted on the DP World Tour website. "Obviously hitting shots is tricky with all the gusts, but the hardest thing is putting.

"You get over the ball and you feel like you've got to be so tense to stop everything moving, but that's the worst thing you can do when you're trying to putt.

"I holed a lot of really good putts from inside five feet today which kept my score respectable.

"It's a great test from tee to green, if you want to call it a test, at the mercy of whatever gust you might or might not get."

Tom Brady has paid tribute to the "tremendous" Los Angeles Rams defense that he is tasked with getting the better of in the NFL playoffs.

In one of the standout games of the Divisional Round, the Tampa Bay Buccaneers host NFC West winners the Rams on Sunday.

The defending Super Bowl champions were beaten by the Rams on the road in Week 3 of the regular season but have home advantage this time around after claiming the number two seed in the NFC.

Tampa Bay eased to a 31-15 win over the Philadelphia Eagles in the Wild Card Round, while the Rams also encountered few problems in beating the Arizona Cardinals 34-11.

A star Rams defense, which includes the likes of cornerback Jalen Ramsey and defensive tackle Aaron Donald, held Arizona to just 183 yards.

It was the second-fewest total yards allowed in a playoff game in franchise history, behind only their 1989 Championship Game win over Tampa Bay.

Brady does not need any reminders about how difficult it is to play the Rams, who have won seven of their last eight meetings against the Bucs.

"It's a very, very challenging team," Brady told reporters ahead of the game. "Really good offense, tremendous defense, really well-coached, great specialists, so it can be very, very difficult game for us.

"It's a very talented football team, obviously one of the great teams in the NFL.

"This team does a lot of good things well. Obviously they rush the passer well, they cover you really well in the secondary, get a lot of turnovers - they sack the quarterback, strip sacks. 

"They have a lot of dynamic players. Obviously, Jalen Ramsey is one of the great corners in the league. So between the guys that they have in the secondary as well as the front, you know that you have no place that you can take off. 

"These guys are they can turn you over. They can make big plays like they did the other night when David Long got the pick six [against Arizona]."

Brady and the Bucs will take lessons from the 34-24 regular season defeat, but the veteran quarterback does not believe it can be factored in too much due to both teams changing since then.

He added: "All these games are a little bit independent from one another. 

"Any time you know your opponent, that always gives you a little bit of understanding of kind of what they do well and things you wish you would have done. 

"But it doesn't really matter what happened in October when we played them last. It's really about this game and what we learned from last game.  

"We had a very different team and I think it was a little bit of a different team they had too. It is going to require its own individual performance."

Last season the Bucs put a strong run together to finish the regular season that continued into postseason glory.

Brady, who is now three wins away from winning an eighth Super Bowl, was asked how he always seems to find another gear once the NFL season gets to December and beyond.

"For all of us, it's repeating good process – that is the important part about getting this time of year," added the 44-year-old.

"You don't do much different, you just do more of which got you here. The things that work we do more of and you try to eliminate all the other distractions. 

"I won't do anything extra this week. I just want to do football. That's all I want to do to prepare and get ready. That is how we should all approach it. 

"This isn't the time for trips to the movie theatres, it is time to lock in on football because this is all we have - three days left [of the season] and we have got to earn more. 

"So you just look at it like that, everything you can kind of put off till the end of the year. We just certainly hope the end of the year is not on Sunday night."

The win over the Eagles was Brady's 18th career playoff win by double digits. 

He has more playoff wins by double digits (18) and by single digits (17) than any other QB has total playoff wins (second is Joe Montana with 16 wins).

Adrian Mannarino stumbled across the winning line at 02:33 local time as his late-night efforts at the Australian Open proved too much for last year's surprise package Aslan Karatsev.

A battling third-round performance from Frenchman Mannarino sets up a showdown with Rafael Nadal next, and the 33-year-old will hope he has sufficient energy left for that daunting task.

The left-hander clinched victory after four hours and 38 minutes of hard duelling with Karatsev on Margaret Court Arena, with a scattering of fans staying until the bitter end, long enough to hear Mannarino swear during his victory interview.

The watershed in Melbourne had of course long passed by the time Karatsev netted a backhand on match point.

After his 7-6 (7-4) 6-7 (4-7) 7-5 6-4 win, world number 69 Mannarino said: "I was enjoying it, you know. I love rallying, and I was just feeling in shape today, it was pretty cool to play."

But he was aware the match was running well into the early hours, saying: "I realised I was just looking at the clock sometimes, and I was thinking, 'F***'. I don't feel good to be honest'.

"I'm kind of exhausted. But it was cool, and I was so focused on what I had to do. I was not thinking about the fact I was tired.

"I was like, 'Okay, go get the next point'. The crowd was cool. Some people had a couple of drinks, I guess, and were commentating more than anybody."

Mannarino's win took him into the fourth round in Australia for the first time, and it meant he accounted for the 18th seed, a player who won the Sydney Classic last Saturday.

Karatsev reached the semi-finals at Melbourne Park last year as a virtual unknown, before going on to establish himself over the course of the season.

Remarkably, this Friday night into Saturday morning epic was far from the latest finish in Australian Open history, with Lleyton Hewitt having won a five-setter against Marcos Baghdatis at 04:34 local time in 2008.

Australian Open favourite Rafael Nadal reflected on a "very special week" after he progressed to the fourth round in Melbourne for the 15th time in his career.

Nadal cruised into a two-set lead against Karen Khachanov on Friday, though the Spaniard had to overcome a third-set fightback to win 6-3 6-2 3-6 6-1.

The 35-year-old - who triumphed at the Melbourne Summer Set earlier in January - has won all six of the matches he has played so far in 2022.

Nadal has endured a difficult time with injuries in recent seasons but, with Novak Djokovic out of the picture after his deportation from Australia this week, he has a record 21st grand slam triumph firmly in his sights.

"It is a very special week for me, coming back," said Nadal, who was out of action from August until December, when he played in an exhibition event in Dubai.

"Every single time I am able to play here is very special. I played against a great player and a good friend on Tour. It was my best match since I have come back without a doubt.

"I have gone through some very tough times over the past year, but nights like tonight mean everything.

"I keep fighting and going every day. I put a lot of effort in to be back with where I am today, so I am happy."

Nadal has won all eight matches against Russian Khachanov, and he will face Adrian Mannarino, whose four-set win over Aslan Karatsev concluded late into the Melbourne night.

He may only have won the Australian Open on one occasion, in 2009, but only Roger Federer (18) has reached the fourth round in Melbourne on more occasions than Nadal.

Matthew Stafford is convinced the Los Angeles Rams will have to put up big points to stand any chance of knocking Super Bowl champions the Tampa Bay Buccaneers out of the playoffs.

Sunday's Divisional Round game at Raymond James Stadium will be the third NFL postseason meeting between the Rams and Buccaneers.

The Rams have won the previous two as the teams combined for just 26 points in those games (9-0 Rams in 1989 NFC Championship, 11-6 Rams in 1999 NFC Championship). 

But Stafford, whose side cruised past the Arizona Cardinals in a 34-11 win last week, expects a high-scoring affair this time around.

Their Week 3 matchup this season did see plenty of scoring, and the Rams won 34-24, but Brady is a formidable opponent in the playoffs.

"The biggest thing about going against a guy like Tom is just knowing his consistency and his ability to get his team in the end zone," said Stafford.

"He's done a great job throughout his career, both in New England and in Tampa of scoring points and doing it kind of every which way.

"Whether they're going to run it, throw it, throw it deep, throw underneath – whatever it is, he always has a great game plan to go out there and execute at a high level. 

"So as an offense, we know we need to do the same. We have packed a great defense. Those guys are unbelievable players and dominated the game for us on Monday. 

"But at the same time, as an offense, you know you're going to have to go out there and score points, and enough to compete with the team that's led by Tom. It's a challenge.

"He's shown year in and year out how capable he is at doing that, especially this time of year. So it's a fun, exciting opportunity. We are playing the whole team, but he [Brady] is definitely a big part of it."

The win over the Cardinals was Stafford's first career postseason victory, meaning the Bucs clash will be his first taste of action in the Divisional Round. He only had to throw a season-low 17 pass attempts last week.

"That was just flow the game and nobody's ever talking about that number," he said. "We know we want to be balanced, like we always are. 

"We are just trying to go out there and feel the flow of the game, I think it's a credit to our guys up front, moving those guys in creating rush lanes, our guys did a great job around the football. 

"And then our defense was doing such a good job of giving us a short field. There's so many times where we had the ball with great field position, and those don't sometimes equate to long drives.

"Less plays, less opportunities to throw the football, but I take it as a positive. 

"I love throwing the ball, no doubt, but I love it when I hand it off, and our guys are getting 10 to 12 yards a pop. At this point I'll take [the yards] any way I can get them!

"This is a great opportunity. We've earned these opportunities as a team. I've loved being a part of this team. So I'm hoping that we continue to earn more opportunities. That's the goal at this point.

"Find ways to win games no matter what it looks like – hopefully, it looks great, like it did on Monday night, but sometimes games shakeout all different, you've got to find ways to win them."

England captain Owen Farrell is a doubt for the Six Nations after suffering an injury in training.

The versatile Farrell has not played since November after undergoing ankle surgery he required due to damage done during a 32-15 victory over Australia at Twickenham.

Farrell was due to feature for Saracens in their European Challenge Cup clash with London Irish on Sunday, but the 30-year-old has suffered another setback.

Sarries said in a statement: "Owen was back in full training having recovered from the ankle injury he sustained against Australia during the Autumn internationals. 

"We will have a further update after he sees a specialist early next week."

Farrell's place in the England side has been called into question, but Eddie Jones this week firmly backed his skipper after naming his squad for a Six Nations tournament that the Red Rose start against Scotland at Murrayfield on February 5.

"We believe Owen can get into his best form very quickly and we believe he will be right to play against Scotland," the England head coach said.

“We are hopeful he's going to play this weekend. He has got a good training week with us next week and we will know whether he is right to play. We will just have to wait and see how he goes over the next couple of weeks.

"He's the best person to captain the team. Very clearly, he's the best person in my judgement to captain the team.

"If he's fit and eligible for selection, he will captain the team. If he's not then we will make an adjustment to that."

Courtney Lawes would appear to be the most likely player to take over as captain after leading his country in a win over South Africa in the absence of Farrell.

Duncan Ferguson hailed the work Wayne Rooney has done at Derby County as the former England captain acknowledged he is "flattered" by reports of Everton's interest.

Rooney, England's record goalscorer who had two spells at boyhood club Everton either side his trophy-laden stint at Manchester United, moved into management in 2020 at Derby, where he played out his final year as a player.

In his first half season at the club, Rooney kept Derby up on the final day. However, the Championship club's financial woes came to a head in September when they filed for administration, which was subsequently followed by a 12-point deduction and then a further nine-point penalty.

Yet against the odds, Rooney has Derby off the foot of the table and eight points from safety. 

Everton, meanwhile, sacked Rafael Benitez on Sunday after a defeat to lowly Norwich City capped a dismal run of just one win in 13 Premier League games. They sit 16th, six points above the relegation zone.

Ferguson, as he did in 2019 before Carlo Ancelotti arrived, has taken interim charge and will oversee Saturday's clash with Steven Gerrard's Aston Villa, but Rooney – along with Frank Lampard and Fabio Cannavaro – is a reported candidate, with Belgium having rebuffed an approach for Roberto Martinez.

Asked about the rumours during Friday's media conference ahead of Derby's contest with rivals Nottingham Forest, Rooney said: "I'm the same as everyone else. I see the speculation on social media and in the papers.

"Of course, Everton is a club I grew up supporting and I'm flattered to be brought up in those conversations. But I know Everton will know for them to have any communication with me, they have to go through the administrators.

"I think it's all hearsay as there has been no approach. My focus is on Derby."

Rooney was brought up in Ferguson's own media conference, and the Scot said: "I'm not going to drag on too many names who would be a good fit, but certainly Wayne's done very well at Derby, he's an Evertonian.

"He could be one candidate of many and he's proved himself as a very good manager."

Ferguson – who revealed Real Madrid manager Ancelotti had contacted him this week to offer advice – was pressed on whether he would like the opportunity to manage Everton.

"Maybe, down the line, one day – I always dream about becoming Everton manager – but I've not quite got that experience," he answered.

"My job at the moment is to take the upcoming games, steady the ship and the club will go through a process of identifying the new manager. 

"You never know in football, but my job at the moment is to focus on the next game and that's it. 

"We need a winning manager. A manager who can come and win games of football, build something and get us back up the league."

Everton have taken just five points in their last 12 Premier League matches (W1 D2 L9), the fewest in a 12-game span since earning four points between August and October 1994, and asked about Benitez's departure, Ferguson replied: "I think the results weren't there, we weren't too surprised, I don't think Rafa would be too surprised."

Saturday's game with Villa has plenty of side stories. Liverpool great Gerrard was on the winning side against Everton more often than he was against any other opponent in the Premier League (16), while Lucas Digne is returning to Goodison Park just over a week after he left due to a falling out with Benitez.

Rafael Nadal continued his search for a record-breaking 21st grand slam title with a routine victory over Karen Khachanov at the Australian Open.

The Spaniard, aiming to achieve the record for most grand slams won by a man, cruised past Khachanov with a 6-3 6-2 3-6 6-1 third-round victory at the first major of 2022 on Friday.

Nadal improved upon his perfect 7-0 record against the Russian, who he last faced at the 2019 Davis Cup Finals, and has only ever lost two of 20 sets in meetings between the pair.

The 35-year-old will now wait to see whether he faces Aslan Karatsev, the 18th seed in Melbourne, or Adrian Mannarino in the fourth round.

Nadal raced out the blocks, breaking the 25-year-old at the first time of asking as he grasped a 3-0 lead within the opening exchanges at Rod Laver Arena.

The 28th seed Khachanov fought back to 5-3 down but Nadal produced another dominant service to secure the first set, in which he dropped just one point on his serve.

A marathon first service game of the second set eventually ended with Nadal again breaking Khachanov after a gruelling 13 minutes and seven deuces before claiming the second set in straightforward fashion.

However, Khachanov – who managed silver at the Tokyo Olympics – bounced back in the third with Nadal making numerous mistakes and unable to cope with his mammoth forehand.

Nadal managed to regain his composure in the following set, celebrating enthusiastically after breaking Khachanov's first service game, before outclassing his opponent, who seemed to run out of steam in a match that lasted 2 hours and 51 minutes.

DATA SLAM: Nadal powers on at Melbourne Park

Nadal has lost on only two occasions in his career when boasting a two-set lead, with the most recent coming against Stefanos Tsitsipas in the quarter-final of this tournament last year.

Despite a spirited fightback from the Russian, Nadal moved onto a 72-15 record at the year's first major, with only Roger Federer (102) and Novak Djokovic (82) recording more victories at Melbourne Park.

Naomi Osaka is taking pride from her Australian Open campaign despite suffering a shock third-round exit to unseeded Amanda Anisimova on Friday.

The two-time Melbourne champion fell short in her latest title defence with a 4-6 6-3 7-6 (10-5) loss to Anisimova in a thrilling contest on Margaret Court Arena.

Osaka, who eased past Camila Osorio and Madison Brengle in straight sets in the first two rounds, squandered two match points to overcome 20-year-old opponent Anisimova.

It means the Japanese star has now failed to defend any of her four major crowns, with Victoria Azarenka the last women's player to do so at Melbourne Park in 2012 and 2013.

But competing in her first competitive event since exiting the US Open to Leylah Fernandez in September, Osaka was pleased with her efforts.

"I fought for every point. I can't be sad about that," said Osaka, who nearly walked away from tennis last year.

"I'm not God, I can't win every match. It would be nice to win the tournament, but I can't think of winning the grand slam at the start of the year every time.

"I feel like I grew a lot in this match. The last time I played in New York I think I had a completely different attitude, so I'm really happy, even though I lost. I'm happy how it went."

Osaka's Australian Open title defence has been halted by a breakthrough American talent for the second time, having previously lost to Coco Gauff at the same stage in 2020.

Despite match points passing the world number 13 by, she refused to be too downbeat by the manner of the defeat.

"There are days that I'm going to have bad days, and there are days that I'm going to have great days," she said. 

"It's always random, and I never know, but no matter what happens for me, I just want to leave the court knowing that I fought for every point.

"Today, of course there were things I felt I could improve on, but even with that, I had two match points, and I think that's something that I can be proud of myself for."

Osaka had dropped just one set in her first five matches this season and looked in the mood as she raced ahead against Anisimova.

But Anisimova hit more than twice the number of winners that Osaka managed (46 to 21) to pull off a huge upset and set up a last-16 clash with top seed Ash Barty.

The American lifted her second career title at Melbourne Summer Set 2 earlier this month and has now won 10 of the last 11 matches she has played, including all eight in 2022. 

It is the first time Anisimova has won from match point down since the 2019 Mallorca Open and the youngster was lost for words in her on-court interview.

"I'm speechless. I absolutely love playing in front of you guys [the crowd] in Melbourne. It's honestly so much fun. I can't stop smiling," she said.

"I knew I had to be playing sharp if I wanted to give myself a chance, Naomi is always going to be playing well and she's an absolute champion. 

"I knew I had to step up my game and try to be aggressive, I think that's what I started doing in the second set.

"I'm so grateful I was able to play well and get this win, it means a lot. Stepping on to the court, all I'm thinking is having fun. Every day here is an amazing opportunity."

Ash Barty insisted she had no expectations Naomi Osaka would be her fourth-round opponent at the Australian Open after the Japanese star's surprise loss.

Barty and Osaka were on track to meet in the last 16 in Melbourne before the latter suffered a three-set loss to Amanda Anisimova on Friday.

World number one Barty, who crushed Camila Giorgi 6-2 6-3, always felt there were no certainties despite all the talk about a potential clash against Osaka.

"That was your expectation. My expectation was whoever it would be. I mean, each match is uncertain," she said.

"Each match of tennis, there are no certainties. You have no idea what's going to happen. You just have to navigate your way through as best you can that given moment.

"I have done a good job of that this week. Now it's exciting to get to play Amanda again. We've played before. It will be nice to play each other again in a big match."

Barty and Anisimova will meet for the first time since their 2019 French Open semi-final, which the former won on her way to a maiden grand slam title.

That match was a "turning point" in Barty's career. After losing the first set despite leading 5-1, Barty fell 3-0 behind in the second, only to fight back for a 6-7 (4-7) 6-3 6-3 victory.

"I try to forget, but also, I remember that I learned a lot from that moment," Barty said.

"That was a turning point in my career, and you have to be able to take learnings from those moments, as hard as they are sometimes, and I was able to navigate and find a way through.

"At that point in my life, in my career, it was a massive turning point.

"Obviously it feels like it's a lifetime ago, but some of those memories are still really vivid. Without a doubt we will take that and use that experience, use those feelings and those emotions as best we can come Sunday."

Novak Djokovic's deportation from Australia was "unjust" and the world number one will need time to move on from the saga, according to his long-time coach Marian Vajda.

The 20-time grand slam winner was denied the chance to claim a record-extending 10th crown at the Australian Open after having his visa cancelled on public health grounds.

Despite being unvaccinated against COVID-19, Djokovic had been given a medical exemption to travel to the country, only for that to be blocked by border officials.

He won his initial appeal to re-approve his visa, but immigration minister Alex Hawke used separate powers to revoke it again and a Federal Court upheld the decision.

The long-running case came to an end on Monday when Djokovic arrived back in Serbia, having reluctantly accepted the court's decision.

But Vajda, who has been part of Djokovic's coaching team for each of his grand slam titles, does not agree with the Australian government's handling of the situation.

"I still don't understand why they did it to him," Vajda told Slovakian outlet Aktuality. 

"It was an unhealthy and unjust decision, based on the assumption that Djokovic could do or influence something that had not yet happened.

"I can't imagine how he handled it. It must have been a huge suffering.

"He humbly endured all measures. But what they did to him must mark him. It is clear that it hit him mentally. 

"It will hurt him for a long time and it will be difficult to get it out of his head. However, I know him very well. Novak is strong, resolute and has not yet said his last word in tennis."

In a further blow for Djokovic, who has stood firm on his refusal to be vaccinated, it emerged this week that the Serbian may also miss the France Open later this year.

That is after stringent laws were passed in France ahead of May's tournament at Roland Garros that will make proof of vaccination status mandatory to enter sporting arenas.

"I don't understand this," Vajda added. "Why is it important for them to announce this now about the tournaments that will take place in May?

"The world doesn't even know what will happen to the pandemic in a month.

"I do not want to underestimate the whole situation. It is serious in the world. But what is the purpose of discussing it now in January? Is it still about sport?"

Defending Australian Open champion Naomi Osaka squandered two match points as she suffered a shock third-round exit at the hands of unseeded Amanda Anisimova on Friday.

Osaka eased past Camila Osorio and Madison Brengle in straight sets in the first two rounds but fell to a 4-6 6-3 7-6 (10-5) loss to Anisimova in a thrilling contest.

Anisimova, who won her second career title at Melbourne Summer Set 2 earlier this month and is now 8-0 for the season, will face top seed Ash Barty in the last 16.

Two-time Australian Open winner Osaka had won 24 of her past 25 matches in Melbourne and made a fast start against Anisimova by breaking her opponent in the first game.

She held serve to ease ahead on Margaret Court Arena, but Anisimova battled back well in the second set.

The world number 60 broke Osaka in the fourth game with a sublime disguised backhand drop and served out the set in a relatively straightforward manner.

Anisimova continued to dig in and saved two match points in the 10th game to help pave the way for a decisive first-to-10 tie-break.

Osaka had no response to her opponent's accurate hitting as she fell 3-0 behind and, while she did bring it back to 3-2 and 5-4, Anisimova took five of the next six points to advance in a big upset.

DATA SLAM: Osaka outgunned by Anisimova

Osaka had dropped just one set in her first five matches this season and looked in the mood as she raced ahead against Anisimova.

But the American youngster fired in 11 aces and hit more than twice the number of winners that Osaka managed (46 to 21) to pull off the victory.

With this defeat, Osaka has now failed to defend any of her four major crowns, with Victoria Azarenka the last women's player to do so at Melbourne Park in 2012 and 2013.
