Casper Ruud followed Rafael Nadal out of the Australian Open and admitted his decision to play through much of December rather than have an off-season may have been a mistake.

The Norwegian second seed, who reached finals at the French Open and US Open last year, had been hoping for another deep run this fortnight, only to run into an in-form Jenson Brooksby.

After a 6-3 7-5 6-7 (4-7) 6-2 defeat in three hours and 55 minutes on Rod Laver Arena, Ruud was asked about his decision to head to Latin America for a lucrative exhibition jaunt with Nadal at the end of the 2022 campaign.

He planned to take a break in February instead, but can now begin that early after going out in round two in Melbourne.

The same goes for top seed Nadal, who was already heading for defeat to Mackenzie MacDonald on Wednesday before an injury compounded his misery.

Ruud's initial reaction to being questioned about his busy December was to be defensive, saying: "It's very easy to sit here now and say that was bad for maybe both Rafa and I due to the fact that we lost early here.

"At the same time, I see no reason why we couldn't have a good Australian Open or made better results down here. I think it's coincidental sometimes."

He spoke of the talent among fellow tour players making every player vulnerable, and the "small margins" between victory and defeat.

Asked whether he had any break at all, Ruud outlined how he left for the Latin America trip on November 21 and returned in early December, before heading off on a week's holiday to the Maldives. He then stopped for a training block in Abu Dhabi on the way home and played two matches at the Mubadala exhibition event.

At the end of this season, Ruud might insist on a longer break and a focused training block.

"It was maybe not enough to be able to perform well here this year," Ruud said. "So it will be considered by me and my team what we will do in December this year, and if this was the right way to prepare for Australian Open or not.

"Maybe it looks like it was not the right way, but there are many factors that come into play. I have done what I felt was the right preparation but wasn't able to perform and win as many matches as I hoped here this year."

Newcastle United have extended Loris Karius' contract until the end of the season.

The former Liverpool goalkeeper joined on a short-term contract in September following an injury to back-up Karl Darlow.

Martin Dubravka's return from a brief loan at Manchester United might have suggested Karius would depart again upon the conclusion of his initial deal.

But Newcastle announced on Thursday that the German – who is yet to make a competitive appearance – will be kept around until June.

The news comes after speculation began linking Darlow with several Championship clubs.

Taylor Fritz and Alexander Zverev were sent packing from the Australian Open as wildcard Alexei Popyrin and lucky loser Michael Mmoh sprang major shocks.

Australian Popyrin said he was living a dream after beating the fancied Fritz in an epic second-round match lasting four hours and two minutes on John Cain Arena.

American Mmoh, whose mother has Australian citizenship, knocked out former world number two Zverev just moments later on Margaret Court Arena.

Their exits followed the shock defeat for second seed Casper Ruud earlier in the day, as Novak Djokovic's half of the draw lost a host of big names.

Wildcard Popyrin won 6-7 (4-7) 7-6 (7-2) 6-4 6-7 (6-8) 6-2 against American eighth seed Fritz, revelling in the chants of "Popy" from the crowd afterwards.

The 23-year-old was close to tears, his voice breaking, after reaching the third round of a grand slam for the fifth time.

"This win, it means so much to me," Popyrin said. "I had the toughest year last year, didn't win many matches. I've won as many matches this year as I won in the whole of last year, and it's only January.

"Pre-season I put my head down and worked as hard as I could. I don't want that feeling I had last year ever again.

"I wrote that down to myself in my head, and I'm going to keep working, I'm going to keep pushing, I'm going to keep trying to go all the way."

Addressing the crowd, Popyrin added: "I love this feeling. I want more of this feeling. I want you guys to have this feeling more. I love you guys so much, thank you."

He is coached by former top-20 star Xavier Malisse and felt the Belgian's influence against Fritz.

"I was playing four hours, and me and my coach were locked in, it was like two against one against Fritzy. We had the same thoughts all the time," Popyrin said. "This is the dream for me and I don't want to wake up at all."

Mmoh was beaten by Aleksandar Vukic in the final round of qualifying but received a call into the draw at the last minute, after a late withdrawal, allowing him to cancel a flight home.

The world number 109 will face fellow American JJ Wolf next, for a place in round four, having ousted 12th seed Zverev 6-7 (1-7) 6-4 6-3 6-2.

Mmoh's father, Tony, represented Nigeria and won a match at the Australian Open in 1988.

"Life is crazy," Mmoh said. "Right when you think everything is looking dim, everything is looking dark, there's light at the end of the tunnel.

"My week is proof of that. I could easily have been in the States, was ready to be in the States, had my bag packed, my flight booked, I was meant to leave yesterday morning. The fact I'm playing Margaret Court is insane.

"If you look at my box over there, there's about five to seven Aussies. I used to come every single Christmas to visit them, unfortunately my mum couldn't be here, I feel like I'm half Australian because of them and I love you guys. This is like my second home now so might as well make it a homecoming.

"It's the biggest win of my career hands down. Coming out I felt the nerves a little bit. I settled down at the end of the first, and at that point I told myself I shouldn't even be here. I told myself on match point if I get a chance just go for it, because I shouldn't even be here."

Nikola Jokic wants to be remembered as a "really good team player" after making franchise history in the Denver Nuggets' 122-118 triumph over the Minnesota Timberwolves.

The two-time reigning NBA MVP contributed 31 points, 13 assists and 11 rebounds as the Nuggets improved to 32-13 on the season to sit top of the Western Conference.

Jokic now has 3,686 career assists, surpassing the tally of Alex English who had 3,679 in Nuggets colours. Moreover, he has reached his tally in 568 games as opposed to English's 837.

English himself paid tribute to Jokic's achievement, intimating he foresees a third MVP accolade in the near future, posting on Twitter: "I knew that eventually my all-time assist record would be broken. I'm honored to see that it's 2 time, I mean 3 time MVP of the NBA do it. Congrats big fella."

Jokic was typically humble when asked what it meant to earn a piece of Nuggets history.

"When you have a lot of assists, it just shows that you're a good team player," he said.

"That's something I want to be. I want everybody to remember me as a guy who was a really good team player."

Team-mate Jamal Murray, who nailed a game-tying three-pointer with a little over two minutes remaining, then hit the bucket that put the Nuggets into a lead they did not let go of, said of Jokic: "We clapped a little bit. That's a lot of passes. That's pretty impressive."

The Nuggets are next in action against the Indiana Pacers, who are 23-23 and ninth in the Eastern Conference, on Friday.

LeBron James could do with a break, and Los Angeles Lakers coach Darvin Ham admits he fears he might be "running him into the ground".

James had 32 points, eight rebounds and nine assists in a 116-111 defeat to the Sacramento Kings on Wednesday, a third tight loss for the Lakers in their last four games.

They stand at 20-25 for the season, despite the impressive efforts of their talisman.

James has scored 30 points or more in 13 of his last 17 games, but the Lakers have only won nine of those contests.

He is taking on a heavy share of the burden in the injury-forced absence of Anthony Davis, who is expected back in action in February.

Only once in his last eight games has James spent less than 35 minutes on court, and Ham might have to do something about that.

Ham said: "I feel bad about that. He's playing at an amazing level, but we can't run him into the ground. That was one of my main goals coming into this season. Here he is with 36 and a half [minutes] again tonight.

"We just have to manage him and have clarity in terms of scaling back his minutes some. And with the non-game days, being smart. His preparation is always on point, but we can still hold him out of some things that we may do on the court.

"He's a high-IQ basketball player, so he understands he can sit there and watch something and have it all figured out defensively and offensively.

"It is a concern. My staff and I, we talk about it all the time. It's just tough because he's such a competitor. We're in these games and he wants to win and we want to win, so you kind of lose sight of the minutes until you come back and see the stats sheet after the game.

"You're like, 'Oh hell'. We're going to figure it out. We have a team of very smart people – our medical and training staff and our coaching staff.

"We all put our heads together and see what the best course of action is to give him whatever rest can be gained, not just going forward in the short term, but the long term as well."

De'Aaron Fox led the Kings with 31 points against the Lakers, and Sacramento have now won five successive games to improve to 25-18 for the season.

The Lakers will be back in action against the Memphis Grizzlies on Friday, with Ham looking for more from his team.

Ham said: "It sucks to lose these close games, but I still feel wholeheartedly at some point we're going to break all the way through. We're competing in my opinion at a very high level."

Rafael Nadal faces up to eight weeks out of action with the hip flexor injury he sustained on his way out of the Australian Open.

The defending champion and top seed in Melbourne was bundled out 6-4 6-4 7-5 by world number 65 Mackenzie McDonald on Wednesday, struggling to move around the court during the closing stages of the contest.

He refused to retire and afterwards confirmed he aggravated an issue he had been suffering with for a couple of days. The 36-year-old Spaniard knew the problem he had been suffering with for a "couple of days" had worsened, but he was unsure exactly what was causing it.

Now Nadal has clarity, receiving details of the injury after tests on Thursday.

He knows that provided all goes to plan, he should be back on court for the clay-court stretch in Europe leading up to the French Open, where the 14-time winner is also the defending champion.

Nadal wrote on Twitter: "Good afternoon. I have carried out medical tests after the defeat yesterday. The MRI shows a grade two lesion in the iliopsoas of the left leg. Now it's sports rest and anti-inflammatory physiotherapy. Normal recovery time six to eight weeks."

The 22-time major winner may struggle to get back to full fitness in time for the Indian Wells and Miami Masters 1000 events in March.

Those are due to be preceded on his schedule by a high-profile exhibition match in Las Vegas against Carlos Alcaraz on March 5; however, both men are presently injured, raising doubts over whether that will go ahead.

Nadal was distraught to suffer yet another injury setback, after severe foot and abdomen problems hit his 2022 season.

"In terms of sports and in terms of injuries and tough moments, I mean, that's another one," Nadal said on Wednesday. "I can't say that I am not destroyed mentally at this time, because I will be lying."

LaMelo Ball is confident his latest ankle injury will not keep him out long despite exiting the Charlotte Hornets' 122-117 win over the Houston Rockets on Wednesday.

Ball hurt his left ankle for the third time this season in the third quarter when team-mate P.J. Washington landed on him as both jumped to block a Jabari Smith shot.

The Hornets point guard and 2020 NBA Draft third pick overall remained on the ground in pain and appeared unable to bear weight on his left leg as he was helped to the locker room. He was ruled out with a "left ankle sprain".

"I can walk and everything, so I'll just take it day by day and see what it is," Ball told reporters.

"I feel a little better. It don't feel like them other ones so I think I'll be straight."

The game was only Ball's 21st this season, enduring an interrupted campaign where he is averaging 24.0 points, 5.4 rebounds and 8.4 assists.

Ball said he would not require an MRI scan while Hornets head coach Steve Clifford was a bit more circumspect.

"We'll see how he feels tomorrow and that's really it," Clifford said.

Casper Ruud made two grand slam finals last year, but his 2023 Australian Open campaign fell to pieces with a shock second-round loss to 22-year-old Jenson Brooksby.

American Brooksby prevailed on his fifth match point, after fluffing three in the third set, when second seed Ruud hit a return long. That sealed a 6-3 7-5 6-7 (4-7) 6-2 victory in three hours and 55 minutes on Rod Laver Arena.

Ruud's demise on Thursday means he joins top seed Rafael Nadal in exiting early in Melbourne, with the Norwegian departing in the Spaniard's wake after struggling through the first two sets before a medical time-out prior to the third.

Ruud staved off three match points at 5-3 down in the third, when Brooksby got tight with victory in sight, before winning the set in a tie-break.

However, Brooksby regained his composure in the fourth set and broke twice early to open up a 3-0 lead, barely looking back.

Brooksby's triumph is the biggest of his career, having only ever previously beaten one top-10 player, Stefanos Tsitsipas, at last year's Indian Wells. It also provides an early highlight in Brooksby's first Australian Open, having missed out in 2022 after testing positive for COVID-19 on the eve of the tournament.

"I was just really proud of my mental resolve after that third-set battle didn’t go my way," Brooksby said during an on-court post-match interview. "I thought I was playing really strong. I didn’t want to lose my focus out there."

Ruud, who was the runner-up at both the 2022 French Open and 2022 US Open, could not match Brooksby's 50 winners, while the Norwegian committed 55 unforced errors. He also failed to capitalise on Brooksby's unconvincing 57 per cent first-serve percentage.

Data Slam: Americans maintain winning form in men's singles

Brooksby's triumph sets up a third-round date with compatriot Tommy Paul as the Americans continue to make waves in the men's singles draw. It was another American, Mackenzie McDonald, who upset Nadal on Wednesday, while a flood of US stars have reached the third round.

Hakan Calhanoglu relished Inter's Supercoppa Italiana win over Milan more than most, saying karma came back to bite the Rossoneri.

The former Milan player, who switched allegiance to Inter on a free transfer in 2021, faced mockery from a number of former team-mates when Stefano Pioli's team won last season's Serie A title.

Zlatan Ibrahimovic was among those who invited scorn to be poured during Milan's celebrations, but Inter's 3-0 victory on Wednesday not only gave them the first silverware of the Italian season, it also gave Calhanoglu a chance to hit back.

"It was a very important victory, even more so for me. I'm very happy. We were hungry, we showed what we are worth on the pitch," Turkish midfielder Calhanoglu said.

"I always prefer to shut up, it was tough for me to see things I didn't expect. Karma comes back, and today we were hungry."

Speaking to Italian broadcaster Sport Mediaset, Calhanoglu said: "They have to respect the 3-0, we sent them home quickly. We ate them up."

On the prospect of a push for the Scudetto, Calhanoglu added: "We will believe it until the end. Let's continue like this."

Napoli have made a runaway start to the season, opening up a nine-point lead over second-placed Milan after 18 rounds of games, with Inter a further point back.

The Supercoppa win on Wednesday over Milan came at King Fahd International Stadium in Riyadh, with Inter's goals coming from Federico Dimarco, Edin Dzeko and Lautaro Martinez.

The next meeting between the city rivals comes in Serie A on February 5, with Inter the home side as they face Milan at the San Siro stadium the clubs share.

The Memphis Grizzlies' achieved a franchise record 11th straight win with Desmond Bane and Ja Morant starring in a thrilling 115-114 victory over the Cleveland Cavaliers on Wednesday.

Darius Garland had a three-point shot on the buzzer blocked by Dillon Brooks, after Steven Adams tipped in with 16 seconds left after Morant's miss.

Bane top scored for the Grizzlies with 25 points, including five-of-eight three-point shooting. Morant added 24 points with eight assists for Memphis, who improved to 31-13, along with 20-3 at home.

Morant had spent time in the locker room in the first quarter after copping a knee to his neck, but re-entered the game in the second quarter.

Game-winner Adams scored 13 points with 10 rebounds and four assists, while Jaren Jackson Jr had an excellent all-round game with 15 points, seven rebounds, two steals and four blocks.

Memphis also managed an 11th consecutive game with 115 or more points.

The Cavs were missing Donovan Mitchell due to a groin strain, with Garland top scoring with 24 points on five-of-11 three-point shooting along with 14 assists.

Caris LeVert added 23 points with four rebounds and six assists, with power forward Evan Mobley scoring 18 points and bringing down 15 rebounds with two blocks. The Cavs are now 28-18.

Trae downs Doncic as Hawks win fourth straight

The Atlanta Hawks continued their run of momentum with their fourth straight win in a 130-122 victory over Luka Doncic's Dallas Mavericks.

Dejounte Murray scored 30 points, making four-of-six three-pointers, while John Collins added 19 along with 18 from Trae Young plus 12 assists, as the Hawks secured a season-best four-game winning streak to move above .500 at 23-22.

Doncic, who was traded as a top-five pick for Young at the 2018 NBA Draft, scored 30 points for the Mavs, but only 11 after quarter-time, while he gave up seven turnovers.

Jokic adds another franchise record in Nuggets win

Nikola Jokic recorded his 14th triple-double of the season as he surpassed Alex English for the most assists in franchise history in the Denver Nuggets' 122-118 win over the Minnesota Timberwolves.

The MVP candidate finished with 31 points, 11 rebounds and 13 assists, going past English's 3,680-assist franchise record with a dime for Kentavious Caldwell-Pope.

Jamal Murray added 28 points for the Nuggets, who secured their eighth straight win and 15th successive victory at home to remain top in the west, at 32-13.

Boston Bruins head coach Jim Montgomery heaped praise on Patrice Bergeron but says he will undergo X-rays after copping a puck to the face in Wednesday's 4-1 win over the New York Islanders.

Bergeron headed down the tunnel early in the third period after a deflected slap shot from David Pastrnak missed his visor and hit him in the face.

The Bruins captain was in apparent pain, having medical attention, but would emerge back on the bench later in the period, helping his side round out a third straight win.

Despite returning to the ice, Montgomery revealed Bergeron had not been cleared by medical staff yet.

"How much respect I have for him coming back after, I know the puck got deflected, but it hits him up high and in the face," Montgomery told NESN.

"The admiration I have and everybody has for him coming back to try to help the team win after that is immense.

"We're hoping that all the X-rays come back good."

The Islanders had taken a first-period lead from Zach Parise but Bruins defensemen Charlie McAvoy and Derek Forbort responded with goals 4:12 apart in the second period to claim the advantage.

Brad Marchand and Trent Frederic added third-period goals for Boston with Charlie Coyle having two assists, while goal-tender Linus Ullmark made 25 saves in his 100th career win.

"I couldn't be more happy, it's been overwhelming," Ullmark said. "I have a lot of gratitude playing with the boys who work so hard every night."

The Bruins are the NHL's only 30-win team, improving their record to 35-5-4.

Real Betis head coach Manuel Pellegrini lamented another penalty shoot-out defeat as their Copa del Rey defence ended at the hands of Osasuna in the round of 16 on Wednesday.

Betis and Osasuna finished 1-1 after normal time with David Garcia netting a 90th-minute goal for the visitors to level after William Carvalho's 62nd-minute opener.

The hosts went up again in extra-time from Youssouf Sabaly but it ended 2-2 with Ruben Garcia equalising, before the visitors won 4-2 on penalties, with Sergio Canales and Guido Rodriguez spurning their spotkicks.

That defeat comes a week after Betis' 4-2 shoot-out loss to Barcelona after a 2-2 draw in the Supercopa semi-final in Riyadh. It also ends Los Verdiblancos' Copa del Rey defence.

"It has been a very tough week due to the cup elimination against Barcelona on penalties, where we were also superior in the 90 minutes, as has happened to us against Osasuna," Pellegrini told reporters.

"At the last minute, for not clearing a ball they tied us, after being superior for 90 minutes. We have to continue competing although it has been a very hard week and we must compose ourselves."

Osasuna converted all four of their penalties, like Barcelona did a week ago, although Pellegrini had no issue with goalkeeper Claudio Bravo.

"Things happen in football," he said. "You don't have to reproach him for anything from penalty shootouts.

"The one who shoots has more options to put it in than the goalkeeper to clear it. It's not the goalkeeper's problem."

Pellegrini conceded the defeat hurt, with Betis now to focus on LaLiga, where they are sixth, along with the Europa League, where they are in the round of 16.

"It's a mental and physical blow," the Chilean said. "We've lost two competitions on penalties.

"We have to keep looking forward. We have to keep fighting for the league and we also have the Europa League."

Tottenham head coach Antonio Conte is questioning his long-term future after a traumatic period following the deaths of three close friends, Gian Piero Ventrone, Sinisa Mihajlovic and Gianluca Vialli.

The 53-year-old Italian hinted that his stint as Spurs boss, where he has a year-long extension on his deal that expires at the end of this season, could be drawing to a close.

Conte worked closely with Ventrone as Spurs fitness coach, before his passing in October. Mihajlovic and Vialli are former club and country teammates who passed away in December and January respectively too.

"This season is a difficult season under personal aspect because to lose three people I knew very well, first Giampiero, then Sinisa and now Gianluca, it was not simple," Conte told reporters.

"When this kind of situation happens, they bring you to have important reflection. Because many times we think and we give a lot of importance to our work and we forget the family.

"We forget that we can all have we need, to have more time for us. The season is a difficult season for me on the personal aspect, and this season is making me to have important reflection about my future."

Conte, who took over at Tottenham in November 2021, resides away from his family in Italy but flies back when possible. His daughter Vittoria is studying for exams, with wife Elisabetta remaining in Rome with her to assist her education.

"You understand that when you work and the work is at the top of your mind in your head, and maybe many times we forget to stay with family, we forget to spend time with friends," he said.

"But this is our passion. And for the passion, we lose a lot of thoughts and when this kind of situation happens, I think that you start to think that maybe sometimes it's also good to give more time to your family and your friends and also to yourself. That work is not everything in life."

The Italian added that living away from family during such a traumatic period had taken its toll on him.

"Having my family in Italy is not good," he said. "But when you have a son or daughter or kids [going to] school, you have to respect them because if every year or every two seasons you have to move your kids and totally change the environment, I don't want to affect the life of my family.

"Sometimes it's important to make decision or to sacrifice [your job] and to stay [with them], but I have a family that try to support me and be here in every moment they can. This kind of situation becomes more difficult when things like this happen like with Gianluca, Giampiero and Sinisa."

Tottenham, whom Conte guided to fourth spot last season, are fifth in the Premier League with 33 points from 19 games, while they have qualified for the Champions League last-16 where they will face Milan.

Spurs face champions Manchester City in the league on Thursday amid a run of eight games before the end of February.
