Denis Shapovalov hit out at chair umpire Carlos Bernardes in an extraordinary outburst during his Australian Open clash against Rafael Nadal.

Shapovalov was furious with Bernardes' decision not to call a time violation against Nadal after the Spaniard left him waiting between the first and second sets on Rod Laver Arena on Tuesday.

Nadal had taken the first set 6-3, but forced the Canadian 14th seed to wait before he could serve to start the second.

"Started the clock so long ago, he's still not ready to play. You've got to call him," Shapovalov said to Bernardes.

After Bernardes opted against doing so, Shapovalov said: "You guys are all corrupt."

Nadal and Shapovalov met at the net between the first and second games of the set in a brief discussion that eased the tension.

After Nadal led 6-3 6-4, Shapovalov hit back to take the third set 6-4 on a hot day in Melbourne.

Madison Keys is enjoying being the underdog after moving into the Australian Open semi-finals on Tuesday.

The American was too good for Czech fourth seed Barbora Krejcikova 6-3 6-2 in their quarter-final, played on a warm day in Melbourne.

Keys reached her fifth career grand slam semi-final, but first since the 2018 US Open.

Riding a 10-match winning streak after claiming just 11 victories in all of 2021, Keys is staying focused as her run continues in Australia.

"I honestly feel pretty neutral, to be completely honest with you. I have gone into every match thinking I can absolutely win any match that I'm out on the court," she said.

"I will say it's been kind of nice to be the underdog for the first time in a long time.

"It's really just not even in my head about winning and losing. It's really just going out, competing, trying to do what the game plan is.

"If that's not working going to Plan B. The rest is kind of not even getting into my brain."

The heat on Rod Laver Arena seemed to get to Krejcikova, the French Open champion taking a medical timeout late in the first set.

Krejcikova said she would learn a lot from her run after struggling with the heat on Tuesday.

"Today it was the heat with some physical conditions that started to bother me during after five games. I mean, from there on, you know, I just couldn't put it together," she said.

"Just still I didn't want to end it up. I wanted to finish match. I wanted to try to do my best. Yeah, I wasn't really able to do that. Still I think it's a really good experience and I can learn a lot from it."

Keys will play either Ash Barty or Jessica Pegula in the last four.

Chris Paul inspired the Phoenix Suns to a 115-109 victory over the Utah Jazz as the NBA leaders matched their best start to a season in franchise history.

Devin Booker top-scored for the Suns with 33 points, but it was Paul's season-high 27 that got his side out of a hole against a shorthanded Jazz.

The visitors led 87-85 at the end of the first quarter at Footprint Center and moved to 95-91 early in the second quarter as they went in search of just a third win in 10 games.

But point guard Paul stepped up for the Suns by making his first five shots in the fourth quarter, including a couple of 3-pointers, as the hosts responded with 14-2 to take the win.

Monty Williams' side are now 37-9 for the season, equalling their franchise record from 2006-07, ahead of facing the same opponents again on Wednesday.

Cavs hold off Knicks thanks to Garland

Darius Garland tied LeBron James' streak of 10-or-more assists in five straight games for a Cleveland Cavaliers player over the past decade in a tense 95-93 win over the New York Knicks.

The 21-year-old point guard recorded 12 assists in total and added a critical late 3-pointer as the Cavs held off a late charge from the Knicks, who trailed 86-71 with 9:41 left in Ohio.

Kevin Love led the scoring with 20 points, nine of those coming in just over a minute in the third quarter, as the Cavs went 10 games over .500 for the first time since the days of James in 2018.

Pelicans power past Pacers

Elsewhere in Monday's action, the New Orleans Pelicans trailed for a large portion of the game but had enough in the tank to beat the Indiana Pacers 117-113.

Josh Hart played through the pain barrier to inspire the Pelicans with 22 points and 10 rebounds, adding to Devonte' Graham's 22 points.

The Chicago Bulls put a poor run of six defeats from seven games behind them by beating Oklahoma City Thunder 111-110 in a tense encounter.

Nikola Vucevic's 26 points and 15 rebounds were nearly not enough as the Thunder, who trailed by 28 points, missed a 3-pointer through Shai Gilgeous-Alexander late on to level the contest.

Madison Keys moved into her first grand slam semi-final since 2018 with a straight-sets win over Barbora Krejcikova at the Australian Open.

Keys overcame Czech fourth seed Krejcikova 6-3 6-2 in hot conditions on Rod Laver Arena on Tuesday.

After a hard-fought 50-minute first set, Keys handled the heat the better of the two, closing out a deserved victory.

The win booked Keys a first major semi-final since the 2018 US Open and fifth of her career, with either Ash Barty or Jessica Pegula awaiting her.

After claiming just 11 match victories in 2021, Keys is on a 10-match winning streak, although she was challenged by Krejcikova, particularly early on.

A pair of break points went begging for Keys in the second game before she dug herself out of a 15-40 hole to hold for 2-1.

Keys held after a gruelling 18-point fifth game, one which looked set to be hugely important, after saving four break points.

Another lengthy game followed as opportunities, this time for Keys, came and went before Krejcikova sent a forehand wide to hand the American a 4-2 lead.

Krejcikova took a medical timeout at 2-5, but there was no stopping Keys taking the first set in 50 minutes.

The unforced errors continued to come from Krejcikova and a tame backhand into the net handed Keys a break in the opening game of the second set.

Looking increasingly weary, Krejcikova was broken to love in the third game, although the French Open champion did get one of those breaks back immediately.

Krejcikova continued to fight, but Keys powered away, breaking for 5-2 on her way to the last four.

DATA SLAM: Keys lands top-five win

Keys, the 2017 US Open runner-up, held an 8-20 record against top-five ranked opponents, and 2-6 at grand slams, heading into her meeting with Krejcikova.

The American at least improved that record and deservedly so, getting the better of Krejcikova.

WINNERS/UNFORCED ERRORS
Keys – 27/21
Krejcikova – 12/28

ACES/DOUBLE FAULTS
Keys – 11/1
Krejcikova – 2/4

BREAK POINTS WON
Keys – 4/12
Krejcikova – 1/8

The Green Bay Packers' key decision-makers are united in their bid to bring Aaron Rodgers back next year, Matt LaFleur says.

Rodgers' future will again be debated after the Packers' season ended on Saturday with defeat to the San Francisco 49ers.

The 2020 NFL MVP pushed for a move away from Green Bay last year before eventually returning and enjoying another stellar campaign.

But the Super Bowl once again proved beyond Rodgers, who has not returned to the big game since the Packers' title triumph in February 2011.

Rodgers is 7-9 in the postseason in that time and, despite himself underwhelming in the loss to the 49ers, might now wonder if this team will ever get over the hump.

The Packers, for their part, want Rodgers to come back.

LaFleur confirmed on Monday his desire to have the QB return was shared by the rest of the organisation, despite the saga surrounding his future at the start of the season.

"Every conversation that I've been involved in with Gutey [Brian Gutekunst, general manager] and Russ [Ball, director of football operations] and Mark [Murphy, team president], we're all on the same page there," the coach said. "There's no debate."

LaFleur added of Rodgers: "I want to be respectful of his process, whatever he needs to go through to make the best decision for himself.

"And certainly we would love for him to be a Packer and be a Packer to the day he decides to retire."

Rodgers has played 213 games for the Packers, throwing 449 touchdown passes – ranking fifth all time in the NFL and first for Green Bay, ahead of Brett Favre (442).

Tom Brady has not yet made a decision on retirement, but the Tampa Bay Buccaneers will give the quarterback "all the time he needs".

The Bucs' season ended on Sunday with a dramatic Divisional Round defeat to the Los Angeles Rams, going down 30-27 after Brady had led his team back from 27-3 down to tie the game.

But talk before the game had suggested it could be Brady's last if Tampa lost, as transpired.

The 44-year-old told his Let's Go podcast that he will be making any decision together with his family, refusing to rule out the possibility of quitting the NFL after seven Super Bowl triumphs.

"Playing football I get so much joy from. I love it," Brady said on the podcast. "But not playing football, there's a lot of joy in that for me also now, too, with my kids getting older and seeing them develop and grow.

"So all these things need to be considered and they will be."

After two outstanding years with the Bucs, Brady said he would only continue if he was operating at "a championship level".

The veteran QB surely still represents Tampa's best possible option under center, but coach Bruce Arians insisted on Monday he would give Brady time.

"I haven't talked to him yet," Arians said. "He'll take all the time he needs and we'll see."

The Bucs had won the championship at the end of the 2020 season and brought the entire team back for a title defence, but an ageing group could not deliver again.

There will be no "rebuild", though, as Arians responded to that suggestion: "No, I think it's just a reload, like it is every year.

"For us, free agency will be our guys. We'll see how many we can get back and build the team from there. I always look forward to that part of it and the draft.

"Each year is so different and so new. Last year, to get everybody back, that was amazing. I doubt we can do that again this year, but we're still going to give it our best."

Tight end Rob Gronkowski, a team-mate of Brady's with the New England Patriots and then the Bucs, insisted his future was not necessarily linked to the QB's.

"Whatever Tom does Tom's going to do," he said. "I'm sure that he needs time to himself, too, to see where he's at at this stage. We'll see in couple of weeks where I'm at."

The Los Angeles Lakers are set to welcome Anthony Davis back from injury against the Brooklyn Nets on Tuesday.

Davis has been upgraded to probable for the game at Barclays Center, having been out for almost six weeks with an MCL sprain.

The return of the eight-time NBA All-Star boosts a Lakers team toiling at 23-24 in eighth place in the West.

Davis has played just 27 games this season and only 15 alongside LeBron James.

Despite LA's poor stretch, which began with Davis in the team, going 13-14 with him in the lineup, James has excelled.

In 20 games without Davis this year, James has averaged 32.7 points, taking on added responsibility with third man Russell Westbrook struggling.

The Lakers will hope both Davis and the rest of the team can now rediscover their best form to recover a title push this season.

CAF is attempting to gather information after a stampede during Cameroon's Africa Cup of Nations game against Comoros.

The incident took place at Olembe Stadium in Yaounde on Monday. No details of how many people were involved or how severely they were hurt were provided by CAF.

CAF's general secretary Veron Mosengo-Omba was sent to visit injured fans as the organisation attempts to gather more information on what occurred. 

The Associated Press reported multiple people had died.

A CAF statement read: "CAF is aware of the incident that took place at Olembe Stadium during the Africa Cup of Nations fixture between hosts Cameroon and Comoros tonight, 24 January 2022. 

"CAF is currently investigating the situation and trying to get more details on what transpired. We are in constant communication with Cameroon government and the Local Organizing Committee. 

"Tonight, the CAF president Dr Patrice Motsepe sent the General Secretary, Veron Mosengo-Omba to visit the supporters in hospital in Yaounde." 

Cameroon advanced to the quarter-finals by defeating 10-man Comoros 2-1. 

Pierre-Emerick Aubameyang has probably played his last game at Arsenal because the club never learnt "how to forgive", according to former Gunners striker Emmanuel Adebayor. 

Aubameyang was stripped of the Arsenal captaincy in December for a disciplinary breach, which reportedly related to him returning late from a trip abroad. 

It was by no means Aubameyang's first indiscretion, having also last year been reminded of his responsibilities after it was claimed he broke COVID-19 guidelines to get a tattoo. 

The punishment did not stop at having the armband taken off him, though, with Mikel Arteta excluding Aubameyang from the squad for the rest of the month. 

His exclusion led to Gabon asking for him to be released early for Africa Cup of Nations duty and Arsenal granted that request, only for him to return to his club without playing a single competitive game in Cameroon as he required medical follow-ups after contracting COVID-19. 

Adebayor knows what it is like to have a fractious relationship with Arsenal and the club's fans, having hit out at both following his 2009 move to Manchester City. Two months later he scored against his former club and ran the length of the pitch to goad Gunners supporters, a celebration that has gone down in Premier League folklore. 

Such have been his experiences with Arsenal, he seemingly sees no way back for Aubameyang. 

He told reporters: "I know he's definitely going to go through a lot because that's Arsenal for you. You can't do whatever you do. 

"They never learn or they never knew how to forgive. So, I know he will go through a lot. 

"But he's a strong player, he's a good player, he's a fantastic player. I wish him all the best. 

"I sent him a message already because we just want him to bounce back. 

"He's our African brother and we want him to keep representing Africa the way he was doing it before the problem. 

"This is what I know because it happened to me also. Not in the same way, but a way back? At Arsenal, I would be surprised. 

"But as I'm telling you, he's a great player so let's see how he ends up." 

Aubameyang has apparently rejected a move to Saudi Arabia, with the 32-year-old said to be eager to stay in Europe. 

Erling Haaland faces further tests on muscular problems sustained in Borussia Dortmund's 3-2 win over Hoffenheim on Saturday. 

After opening the scoring in the sixth minute at the PreZero Arena, Haaland was forced off in the second half after suffering a knock. 

The Norway international will commence treatment for muscular issues this week and now faces a race to be fit for the visit of Bayer Leverkusen on February 6.

A Dortmund statement read: "Haaland was examined in detail on Sunday and Monday. According to the medical report, the Norwegian is suffering from muscular problems, which will require treatment and further examinations in the coming days. 

"We hope that Erling will be back to full fitness as soon as possible and can get back to doing what he loves the most – scoring goals for BVB." 

Haaland has scored 23 goals for Dortmund in all competitions this season. Only Karim Benzema (24) and Robert Lewandowski (34) have registered more among players from the top five European leagues. 

However, among players to have scored more than 10 times, Haaland has the best minutes per goal ratio of 70.4. Lewandowski is a close second with a goal every 71 minutes. 

Sean Payton is yet to confirm to the New Orleans Saints whether he will remain as head coach for the 2022 season. 

Payton has been at the helm in New Orleans since 2006, but reports in recent days have suggested he is far from certain to return next year. 

In their first season since Drew Brees' retirement, the Saints marginally missed the playoffs with a 9-8 record. 

It still marked another fine coaching performance from Payton, who had his team evacuated early in the year due to a hurricane and later had to deal with a number of coronavirus and injury absences. 

Jameis Winston, promoted to a starting role at quarterback in Brees' place, tore his ACL in October following a promising 5-2 start in which he threw 14 touchdown passes and only three interceptions. 

Payton, who is under contract through 2024, has a 152-89 regular-season record – the 13th-best of all time (minimum 100 games) – while he is 9-8 in the playoffs, winning Super Bowl XLIV. 

The Saints hope he will further improve those totals next season, although owner Gayle Benson knows little more than New Orleans fans at this stage. 

"We don't know," she told FOX 8 NOLA on Monday. "You know, who knows? We'll find out soon enough, I guess. 

"I don't think any of us know. But he'll let us know soon enough." 

Comoros put in a tremendous performance despite being without a recognised goalkeeper and having 10 men for most of the game, as they succumbed to a narrow 2-1 loss to hosts Cameroon in the Africa Cup of Nations last 16. 

After booking their place in the knockouts with a famous win over Ghana, Comoros' fairytale quickly turned into a nightmare when a coronavirus outbreak in their camp left them without a keeper for the clash with Cameroon. 

Back-up option Ali Ahamada returned a negative result on Monday but was not authorised to play by CAF, meaning defender Chaker Alhadhur had to be deployed between the posts. 

The task facing Les Coelacantes was made even more daunting inside seven minutes when they lost their captain Nadjim Abdou, who was shown a straight red card after referee Bamlak Tessema Weyesa reviewed footage of his challenge on Moumi Ngamaleu.  

Cameroon struggled to test Alhadhur but finally broke through in the 29th minute when Karl Toko Ekambi dug out a shot that found the bottom-left corner.  

Andre Onana did well to keep out Ahmed Mogni and Mohamed Youssouf in quick succession as Comoros still showed plenty of adventure, with Alhadhur matching his counterpart by thwarting Vincent Aboubakar and Ngamaleu in a memorable double save after the restart.

Aboubakar sold Alhadhur a dummy to finally add to Cameroon's tally in the 70th minute, but Comoros rallied despite their numerical disadvantage and pulled one back through an incredible 35-yard free-kick from Youssouf M'Changama that sailed into the top-right corner. 

It was too little too late for Comoros, though, with their sensational maiden AFCON appearance brought to a harsh end, while Cameroon face Gambia next.
