The Arizona Cardinals have activated J.J. Watt from injured reserve in time for him to make an unexpected return for their Wild Card round clash with the Los Angeles Rams.

Watt was placed on injured reserve in November having undergone what was thought to be season-ending shoulder surgery in October.

However, the three-time Defensive Player of the Year has expedited his recovery and will line up for the Cardinals on Monday as they look to upset their NFC West rivals at SoFi Stadium.

Despite playing only seven games, Watt ended the regular season with the third-most quarterback pressures among Cardinals defenders with 32.

The Cardinals are looking to claim their first playoff win since the 2015 campaign when they lost the NFC Championship Game to the Carolina Panthers.

Coco Gauff reflected on a hugely disappointing Australian Open defeat as the two leading United States players exited the women's draw on day one in Melbourne.

Gauff is ranked 16th, closing on top American Sofia Kenin in 13th, but neither advanced to the second round on Monday.

The 17-year-old was stunned 6-4 6-2 by Wang Qiang in a sloppy display that included 38 unforced errors, with 21 in a second set in which she fell 5-0 behind.

Meanwhile, Kenin was beaten by compatriot Madison Keys, who came into the tournament in high spirits having won her sixth career title – and first since 2019 – at the Adelaide International 2. That run included a semi-final defeat of Gauff.

After her latest loss, Gauff said: "I think just everything disappointed me about today.

"I feel like in the pre-season I worked really hard, and I felt like I was ready to have a good run here. Today I just didn't perform well.

"I think there's a lot to learn from. I think I was playing a little bit tighter than normal.

"So I think next time coming into the first round of a slam, especially after a tough week before, I think I need to just play more free and focus on the moment."

Keys is playing with that freedom, eager to move on from a dismal 2021 in which she won only 11 matches.

"I'm not taking it quite as seriously, that's the biggest difference this year," she said.

Keys already has seven wins in eight matches in 2022, defeating fellow Americans in each of her past three outings.

Of the win over 2020 champion Kenin, she said: "At this point every first round is tough, but when you have to go up against a grand slam champion it's never easy.

"I think knowing that she was going to compete so well, I just had a really good mentality and attitude. I had a couple of opportunities I didn't really capitalise upon and I was able to reset and continue to play well.

"I had my first real run in a slam here, I missed last year, so absolutely ecstatic to be back in Melbourne. It would mean the world to have another run here."

Patrick Mahomes revealed the Kansas City Chiefs were motivated by being "p****d off" by a slow start to the Wild Card round against the Pittsburgh Steelers in their 42-21 blowout win.

The Chiefs were shut out in the first quarter by a Steelers team that snuck into the playoffs as the seven seed and then fell behind when T.J. Watt returned a Mecole Hardman fumble for a touchdown.

But Mahomes took over thereafter, throwing for 404 yards and five touchdowns, a sole interception in the first quarter the only blemish on a blistering performance.

Tight end Travis Kelce also threw a touchdown on a trick play as the Chiefs turned on the style in setting up a rematch of last year's AFC Championship Game with the Buffalo Bills in the Divisional Round.

"I think we were all p****d off at ourselves," Mahomes said in his media conference. "We felt like we weren't playing with enough energy, we felt like we weren't executing at a high enough level and not playing with enough urgency.

"So, I feel like guys really motivated themselves. We all kind of talked, it wasn't like one person talking, it was everybody talking to each other, and we came with a different urgency starting in the second quarter and carried it the rest of the game.

"Playing in the postseason games, we have young dudes who hadn't played yet, so they got to get that experience this week.

"And we have those vets that have been in here before and showed that with how Tyreek [Hill] and Trav [Kelce] stepped up in big ways to kind of get us sparked and get us rolling again."

On the matchup with the Bills, who crushed the New England Patriots on Saturday behind a sensational five-touchdown performance from quarterback Josh Allen, Mahomes said: "Yeah I mean you expect a really good football team that's going to play really hard. We're expecting a fight, we're expecting a battle. 

"They have a great offense, great defense, great special teams, and we played them in the AFC Championship last year, and we know that it's going to be another fight for us if we want to try to move on to the AFC Championship Game this year."

Novak Djokovic could miss out on defending another of his Grand Slam titles, with France passing new vaccination laws that may threaten his ability to compete at Roland Garros later this year.

The 34-year-old will not defend his Australian Open title, with a drawn-out saga concerning his vaccination status culminating in his visa being cancelled for a second time after an intervention from Australian immigration minister Alex Hawke.

But the controversy surrounding the 20-time Grand Slam winner could be set to continue, with French parliament passing stringent vaccination laws ahead of May's French Open.

After French lawmakers comfortably passed the new measures, proof of vaccination status will soon be required to enter a wide variety of public places, including sports stadiums, and the country's sports ministry says there will be no exemptions for professional athletes. 

"The rule is simple. The vaccine pass will be imposed, as soon as the law is promulgated, in establishments that were already subject to the health pass," the ministry said.

"This will apply to everyone who is a spectator or a professional sportsperson, and until further notice.

"Now, as far as Roland Garros is concerned, it is in May. The situation may change between now and then, and we hope that it will be more favourable. 

"So, we'll see, but clearly, there's no exemption."

Djokovic, who is tied with Rafael Nadal and Roger Federer for all-time Slam wins in the men's game, has come in for widespread criticism regarding his failure to be vaccinated against COVID-19, as well as for appearing in public in the days after testing positive for the virus last month.

Meanwhile, Djokovic has arrived back in his native Serbia, travelling via Dubai from Melbourne to Belgrade after losing a last-ditch court appeal to remain in the country.

World number one Ash Barty kicked off her Australian Open title bid with a convincing straight-sets victory over Ukrainian qualifier Lesia Tsurenko on Monday.

The two-time grand slam winner, whose previous best finish on home soil at Melbourne Park was a run to the semi-finals in 2020, prevailed 6-0 6-1 in a time of just 54 minutes.

Barty held serve throughout the one-sided contest with Tsurenko and is now unbroken in 41 successive service games across her last four matches.

"It's certainly nice to be back on home soil and playing as well as I did tonight. It was a lot of fun out here," Barty said in her on-court interview.

"I felt like it was nice and clean. End-to-end I did a good job in adjusting. Tonight it was just nice and solid to get out here and play a decent match and feel like I enjoyed it."

Tsurenko took Barty to three sets when they met in this competition two years ago, but the world number 113 was outclassed on this occasion.

Looking to build on her recent Adelaide International success, Barty eased through the first set as she dropped just 12 points.

Barty was just as dominant in the second set, but she squandered two match points in the sixth game to miss out on a double-bagel to begin her campaign in Melbourne.

Not that it mattered a great deal, though, as the 25-year-old emphatically served out the match to set up a meeting with Italian qualifier Lucia Bronzetti for a place in round three.

DATA SLAM: Barty makes statement start

Barty came through this first-round match with minimal stress and looks in great shape as she bids to become the first Australian to win here since 1978.

The pressure is no doubt on as the pre-tournament favourite, with no top-seeded player in the women's draw failing to make at least round four since Virginia Ruzici in 1979.

Cade Cunningham insisted he was acknowledging his "people" and not taunting the opposition after he was ejected during the Detroit Pistons' loss to the Phoenix Suns.

The Pistons fell to a 135-108 reverse against the NBA-leading Suns on Sunday as they saw two of their players ejected in the second half.

Cunningham was the first to be dismissed in the third quarter, ending an enthralling battle with Devon Booker, for what referee Kevin Cutler later described as "a physical taunt for pointing at the defender".

Cutler was referring to Cunningham's gesture after he slammed past Jalen Smith and immediately pointed in the 21-year-old's direction, leading to his second technical foul.

But Cunningham – who had 21 points, one rebound and four assists before his ejection – provided a different view after the game as he justified his celebration.

"I had my people right behind the bench," said Cunningham, who finished on 9-for-15 shooting in 24 minutes. 

"I went baseline to dunk the ball, and he's right in between me and my people. I probably should've read that situation better. I don't really get into taunting too much. 

"Usually I'm chilling after a play. I realised the situation after he tech'ed me [technical fouled] up, but I didn't think I was going to get a tech. 

"I let coach Monty [Williams of the Suns] over there, let him know, 'Good game,' and stuff like that."

Detroit trailed by 20 at the time of Cunningham's removal, and that increased to 27 by the end of the game after Josh Jackson was also ejected with 41 seconds remaining.

Pistons coach Dwane Casey – whose side are 10-32, the second-worst record in the league – believes his team must manage their reputation by maintaining strong disciplinary levels.

"He [the referee] said Cade pointed at the guy that he dunked on," Casey said after the game. "I didn't see that part. I thought he was pointing towards his teammate. 

"That's why he said he got a technical for and got ejected for, he already had one. I've seen a lot worse things to get ejected for than that. 

"The Josh one, I haven't looked at it yet. He said Josh hit, or pushed, or whatever at [Ish] Wainright. I didn't see that part either, I have to look at that.

"We're not in a position as a team to complain. Let me be the bad guy to fight for us.

"As a young team, we shouldn't get that reputation of complaining to officials. Until we get to that level, we have to button up and zip up and play our butts off."

Despite Cunningham's dismissal, the 20-year-old has been in fine form recently – averaging 17.9 points, 5.7 assists and 4.9 rebounds since November 30 (a span of 18 games).

With the Pistons looking to bounce back with a trip to the Golden States Warriors on Tuesday, Cunningham insisted that his team are heading in the right direction.

"We're still locked in," Cunningham added. "We feel ourselves getting better and growing together. 

"This is a big road trip that we got to go into. We're going to play some good teams. We're excited to take that challenge on and see what we got." 

Rafael Nadal believes it would be "better for everybody" if Novak Djokovic was competing at the Australian Open, while declaring the situation a "mess".

Nadal sits level on 20 grand slam titles with Djokovic and Roger Federer but is the only one of tennis' 'Big Three' featuring in Melbourne.

Federer was ruled out due to ongoing knee injury problems, while Djokovic saw his visa cancelled for a second time on Sunday as he appealed Australia's refusal to let him into the country.

That ruling owed to Djokovic's unvaccinated status and Australia's coronavirus guidelines, leaving the Serbian unable to defend his Melbourne Park crown and seek a record-extending 21st grand slam.

Nadal has previously said he was "tired" of talking about the Djokovic saga, but the Spaniard again offered his thoughts after defeating Marcos Giron in the first round on Monday.

"Almost one week ago when he won in the first instance, the case, he was able to get back his visa and practising. I said the justice has spoken," Nadal told reporters.

"If the justice says his visa is valid and he's able to play here, the justice has spoken, so that's the fairest thing, that he deserves to play here. Yesterday the justice said another thing. I will never be against what the justice says.

"Another thing is what I believe personally and what I believe is the ideal situation personally, no?

"The ideal situation in the world of sport is that the best players are on court and playing the most important events. That's better for the sport without a doubt.

"If Novak Djokovic is playing here, it's better for everybody, no doubt about that. Another thing is what happened. As I said in the beginning, I can't say another thing because I believe that the situation is very clear now."

Pressed for an answer on his relationship with the 34-year-old world number one, Nadal wished his fellow competitor all the best.

"He's not the only one that did bad things in that case," Nadal added.

"Of course, there are more responsibilities on all for this terrible situation that we faced for the last two weeks. But of course, he is one of those responsible, too.

"So on a personal level, yes, I would like to see him playing here. If it is fair or not that he's playing here is another discussion that I don't want to talk anymore about that."

Nadal advanced to the second round in Melbourne with a cruising 6-1 6-4 6-2 victory over American Giron, who is ranked 66th in the world.

That was Nadal's fourth win of the year after triumphing at the Melbourne Summer Set and he appears to have battled through his foot injury, though he still expressed concerns over his fitness.

"It's been a very challenging few months… tough moments with a lot of doubts – there still are doubts," he said.

"But I am here and I can't be happier to be back in Australia in this amazing stadium.

"You never know when you come back from injury, which unfortunately I have a lot of experience with, how things will be, so you have to take it day by day. You have to forgive yourself if things aren't going the proper way."

Awaiting Nadal in the second round of the tournament will be either Australia's Thanasi Kokkinakis or Yannick Hanfmann of Germany.

Novak Djokovic could make an earlier-than-expected return to Australia despite the Serb facing a three-year ban from the country, according to prime minister Scott Morrison.

The world's number-one ranked player, who is level on 20 grand slam titles with Rafael Nadal and Roger Federer, saw his visa cancelled for a second time on public health grounds on Sunday.

Djokovic was attempting to overturn the original decision to refuse his entry into Australia, which was due to his unvaccinated status and the country's coronavirus rules.

That leaves the 34-year-old unable to defend his Australian Open title at Melbourne Park, while he was also handed an automatic three-year ban from the country under immigration law, unless Australia's immigration minister overrules the judgement.

Compelling or compassionate reasons would be needed to do so, but Morrison refused to rule out the possibility of Djokovic making an early return.

"I'm not going to precondition any of that or say anything that would not enable the minister to make the various calls he has to make," Morrison said to 2GB Radio on Monday.

"It does go over a three-year period, but there is the opportunity for [a person] to return in the right circumstances, and that will be considered at the time."

Morrison then insisted that Djokovic, who has already expressed his disappointment with the ruling, and any other entrant to Australia must comply with their rules.

"If you're someone coming from overseas, and there are conditions for you to enter this country, then you have to comply with them," he continued.

"This is about someone who sought to come to Australia and not comply with the entry rules at our border."

The Australian Open started on Monday, with Nadal advancing past Marcos Giron in his first-round match.

Confusion reigned at the end of the San Francisco 49ers' dramatic Wild Card victory over the Dallas Cowboys, but Kyle Shanahan only had a brief doubt his team would have to face a Hail Mary in a bizarre finish.

The Niners controlled the game and held a Dallas offense that had averaged over 400 yards per game in the regular season to just 307 in their 23-17 success.

Yet San Francisco gave the Cowboys a chance to complete a remarkable comeback with 32 seconds left after their failure to execute a quarterback sneak on fourth and inches turned possession back to Dallas.

The Cowboys promptly drove to San Francisco's 41-yard line in just three plays, before a bemusing play call from Dallas to run the ball with quarterback Dak Prescott despite having no timeouts sealed the game for the Niners.

Prescott and the Dallas offense frantically tried to get set up to spike the ball to stop the clock and prevent time from expiring. However, Prescott handed the ball to center Tyler Biadasz to spot the ball.

NFL rules state the ball must be spotted by an official and umpire Ramon George ran in to do just that, colliding with Prescott and Biadasz in the process and leading to a delay that prevented Prescott from spiking it before the clock hit triple zeros, meaning the 49ers never had to face a Hail Mary from the 24-yard line that could have settled a thrilling contest in the Cowboys' favour.

Shanahan and the Niners strode onto the field in celebration after time ran out, with the Niners head coach admitting to brief concern time would be put back on the clock.

"I thought it was over because I saw it live," Shanahan said. "I was very confident it was done. I was just nervous.

"Sometimes when you're real confident you think you see it right. Sometimes it changes. So you're never fully sure until they let you know."

Explaining the false start from tackle Trent Williams that kept the game alive and negated a successful quarterback sneak from Jimmy Garoppolo, Shanahan added: "We just shifted to an unbalanced [line].

"It was on the silent count and it was quarterback sneak all the way, but Jimmy got really excited because of the look. Didn't let Trent get set. He's got to let him get set.

"It ended up not being a problem, though it would have been a struggle to answer that one if it was."

The Niners will next face the top-seeded Green Bay Packers at Lambeau Field on Saturday in a rematch of a Week 3 encounter in which the Packers prevailed on a last-second field goal after some late Aaron Rodgers heroics.

"I'm sure I'll be thinking a lot about it here on the plane," Shanahan said. "But they've had a hell of a year. I'm glad we get an opportunity to go up against them again.

"They've been unbelievable. So, we'll rest up here. We'll enjoy this plane ride, and we'll get back to work right when we land."

Hideki Matsuyama produced a stunning second shot on the first playoff hole to claim victory at the Sony Open in Hawaii as he triumphed over Russell Henley.

The reigning Masters champion had trailed by five strokes on the back nine but produced a surge capped with a birdie at the last to force a playoff with Henley after both finished 23 under par.

Henley's putt on the 18th to win the tournament skimmed the outside edge of the hole and he was left to rue that miss in quite astonishing fashion.

They returned to the same hole for the playoff and Matsuyama, having gone for the 3-wood off the tee, elected to use the same club for his second shot from 277 yards away and could not have hit it any better, sending it to three feet for an eagle putt to secure his eighth PGA Tour title and his third in less than a year as Henley made bogey.

Waialae Country Club holds a special place in Japanese golf history, with it being the course where Isao Aoki became the first player from the country to win on the PGA Tour.

And Matsuyama was thrilled to replicate his achievement.

"I got on a roll, I'm glad it came out this way," said Matsuyama. "To follow him [Aoki] up, I'm over the moon."

Kevin Kisner and Seamus Power were Matsuyama and Henley's closest challengers, finishing in a tie for third, four strokes off the pace.

Naomi Osaka insisted she was unaffected by the saga surrounding Novak Djokovic ahead of the Australian Open.

Osaka opened her title defence at Melbourne Park with a 6-3 6-3 win over Colombian Camila Osorio on Monday.

The lead up to the year's first grand slam was overshadowed by the visa saga around Djokovic, who was deported from Australia on Sunday.

But Osaka, a four-time major winner, said the Serbian world number one's situation had no impact on her.

"I mean, to be completely honest, it didn't really affect me. I saw that it affected the men's draw a little bit so you might have to ask a men's player," she said.

"For me, my goal even before this whole situation is to just focus on myself more, what I need to do to become better.

"I wasn't really, I guess, looking at the news too often."

Osaka was unwilling to be drawn on whether Djokovic, whose visa was cancelled by immigration minister Alex Hawke, should be competing in the tournament.

A two-time champion in Melbourne, Osaka said her focus was on herself – with a second-round clash against Madison Brengle awaiting her.

"I feel like people focus on whatever they want to focus on. It's more like an individual question," Osaka said.

"Me, I'm a tennis player. I'll focus on my matches. You, as I guess an audience, focus on whatever is in the news, no?"

Rafael Nadal made a strong start to his Australian Open campaign, brushing past Marcos Giron in the opening round on Monday.

The Spanish superstar outclassed American Giron in a resounding 6-1 6-4 6-2 victory on Rod Laver Arena.

Nadal, who can claim the outright lead for most grand slams won by a man if he clinches his 21st in Melbourne, was in good form.

Playing his first major since last year's French Open, Nadal – the only former champion in the draw following Novak Djokovic's deportation from the country – was never troubled by Giron.

Nadal reeled off five consecutive games to take the opening set in 24 minutes.

His excellent first set was highlighted by two brilliant winners to break for 5-1 as he completely dominated Giron.

Nadal capitalised on his momentum by breaking in the opening game of the second set, Giron finally stopping the run by holding for 1-2.

The Spaniard maintained his lead and was forced to serve out the set, doing so to 15 to take complete control.

A backhand pass saw Nadal break again in the opening game of the third set on his way to a comprehensive win, with Thanasi Kokkinakis or Yannick Hanfmann awaiting him in the second round.

DATA SLAM: Nadal makes no mistake in opener

Only twice in his illustrious career has Nadal lost in the opening round of a grand slam – at Wimbledon in 2013 and the 2016 Australian Open.

But since his defeat to Fernando Verdasco in Melbourne six years ago, Nadal has not lost a set in the Australian Open first round, continuing that record against Giron.

WINNERS/UNFORCED ERRORS
Nadal – 34/26
Giron – 10/23

The Golden State Warriors felt the absence of Steph Curry and Draymond Green as they fell to a 119-99 loss against the Minnesota Timberwolves on Sunday.

Curry was ruled out with a hand injury and Green missed a fourth straight game with a calf issue as the Warriors lost for a fifth time in their last seven outings.

Jaylen Nowell scored 17 points for the Timberwolves and Malik Beasley added 16, which included five second-half 3-pointers in a one-sided conclusion to the game.

The travel-weary Warriors, playing on the road for a fourth successive time, are now 31-12 for the season and remain second in the Western Conference.

Gobert guides Utah past Denver

Returning from a five-game coronavirus-enforced absence, Rudy Gobert made up for lost time with a double-double in the Utah Jazz's 125-102 win over the Denver Nuggets.

The Jazz had lost four in a row in Gobert's absence, but the center's 18 points and 19 rebounds got his side back on track at the Ball Arena.

Gobert has now recorded 15 straight double-doubles either side of his spell on the sidelines, while Bojan Bogdanovic finished with 21 points.

Nikola Jokic top-scored for the Nuggets with 25 points, 15 rebounds and 14 assists for his ninth triple-double of the season – no player has more.

Suns win again, Rockets looking up

The NBA-leading Phoenix Suns won for a sixth time in seven games with a 135-108 victory over the Detroit Pistons, with Devin Booker scoring 30 points.

JaVale McGee added 20 as the Pistons, who had Josh Jackson ejected in the fourth quarter, fell to a fourth defeat since New Year's Day, each of those by at least 27 points.

Elsewhere on Sunday, the Houston Rockets beat the Sacramento Kings 118-112 to exact some revenge two days on from losing to the same opponents.

Eric Gordon made a clutch bucket with 12.5 seconds left, adding to Christian Woods' 23 points and 14 rebounds as the Rockets won for a second time in three games.
