Max Verstappen heads into Sunday's Qatar Grand Prix well off the pace of Lewis Hamilton's Mercedes and under investigation by the stewards, with the fallout over the title rivals' battle in Brazil refusing to die down.

Verstappen is under investigation for refusing to slow down under waved yellow flags in qualifying.

The world championship leader has been summoned to the stewards having apparently failed to respond to single waved yellows on his final lap after Pierre Gasly suffered a puncture on the pit straight.

If found guilty, he will likely face a grid penalty having qualified second behind Hamilton, who set a blistering time of 1:20.827.

Mercedes' Valtteri Bottas (third) and Ferrari's Carlos Sainz (seventh) are also under investigation for the same offence.

Qualifying came after an elongated drivers briefing that lasted over an hour as they sought clarification over what represents fair driving following the tussle between Verstappen and Hamilton in Sao Paulo, which saw the latter forced off track as they fought for the lead.

Asked if the FIA had succeeded in clarifying the issue, Verstappen told the drivers' media conference: "I think it's always trying to align everyone in having the same process in the way you think, everyone.

"Everyone is different, right? And everybody I think has their own way of racing and defending and overtaking, and of course very hard for the FIA as well to, how do you say it? To get everyone on the same line.

"Of course, they decide but every driver has a different opinion. And I think yesterday [Friday] it was all about sharing their opinions, and then the FIA explaining their process of thought behind it. So, I think we came a long way, and it was a very long briefing. So, yeah, I think at the end it was pretty clear."

Hamilton, though, had a very different view.

"It's not clear. Every driver, except for Max, was asking just for clarity, most drivers were asking for clarity, but it wasn't very clear," he said. 

"So, yeah, it's still not clear what the limits of the track are. It's clearly not the white line anymore, when overtaking but… yeah, we just go for it. We just ask for consistency. So, if it's the same as the last race then it should be the same for all of us in those scenarios and it's fine."

With victory, Hamilton could trim Verstappen's lead to seven points were the Dutchman to finish second, and he has every reason for confidence with his Mercedes taking pole by a gap that surprised even himself.

"Probably the last three races in qualifying we have been ahead of them, which has been a bit of a surprise," added Hamilton. 

"Today definitely wasn't expecting to have as big a gap as that. I looked, I was relatively comfortable and was around tenth or so ahead throughout the session, but to be able to pull out that extra time felt great and it's a great showing of the hard work, all the guys, as I said we were here until midnight last night. The guys were here even later than that. Really great work from everyone.

"Long-run pace is good. We always end up getting closer… or our pace closes up to each other when it comes to race pace and yeah, I think the car is in a good place. It's a difficult circuit to follow so, yeah, I'm looking forward to the start."

The Women's Tennis Association (WTA) has welcomed a video released by China state-run media that appears to show tennis star Peng Shuai, but continued to raise concerns about her safety.

Peng has been widely considered to have been missing since making sexual assault allegations against Zhang Gaoli, the ex-vice premier and member of the Chinese Communist Party's Politburo Standing Committee.

The video was posted on Twitter by Hu Xijin, editor-in-chief of Global Times, who said it was taken on Saturday and shows Peng with her coach and friends in a restaurant in Beijing.

A statement released by WTA chairman and chief executive officer Steve Simon on Saturday said: "I am glad to see the videos released by China state-run media that appear to show Peng Shuai at a restaurant in Beijing. 

"While it is positive to see her, it remains unclear if she is free and able to make decisions and take actions on her own, without coercion or external interference. 

"This video alone is insufficient. As I have stated from the beginning, I remain concerned about Peng Shuai's health and safety and that the allegation of sexual assault is being censored and swept under the rug. 

"I have been clear about what needs to happen and our relationship with China is at a crossroads."

Earlier on Saturday, Hu Xijin had claimed that Peng was safe and well in her own home and will soon "show up in public" to allay concerns about her wellbeing.

Three purportedly new pictures of Peng have been reportedly posted on Chinese messaging app WeChat, along with a "Happy Weekend" message.

A last-gasp penalty from Rhys Priestland denied 14-man Australia a memorable comeback against Wales at the Principality Stadium on Saturday.

Smarting from a 32-15 defeat to England last time out, the Wallabies were up against it when Rob Valetini's red card and a 10-point deficit left them staring at a potentially heavy defeat.

However, Wales – who survived a scare against Fiji after despite Eroni Sau's red card – were pegged back and it required steely nerves from Priestland beyond the 80-minute mark to secure a 29-28 win.

Australia began in brilliant fashion as Andrew Kellaway collected a grubber and touched down, although Dan Biggar quickly reduced the deficit with a penalty, but the match swung firmly Wales' way when Valetini was shown red for a dangerous high tackle that left Adam Beard bleeding, Biggar then kicking a further three points.

Although James O'Connor's penalty put the 14 men ahead, Kurtley Beale was sent to the sin bin for a deliberate knock-on and Ryan Elias scored Wales' first try after good work at the resulting lineout.

O'Connor and Biggar exchanged further penalties and the latter converted after Nick Tomkins intercepted a pass and scored a simple try, with a TMO check allowing it to stand.

Then came the threat of a late surprise. Nic White finished a fine move involving Beale, and although Biggar's boot stretched Wales' lead again, Filipo Daugunu touched down in the corner with O'Connor's kick striking the post to spare the hosts.

Beale's kick then put Australia ahead with two minutes to play, but after winning a penalty inside the visitors' 22 in the 81st minute, Priestland kept his nerve to send Cardiff into raptures.

Marcus Smith nailed a last-gasp penalty as England rounded out their November internationals with a 27-26 win over South Africa in a barnstorming Twickenham Test.

Making only a third Test start, the unflappable Smith made the decisive contribution in a match that looked like getting away from the White Rose after an enterprising performance was mixed with ill-discipline.

England outscored South Africa three tries to one but a penalty count of 18 allowed the Springboks to stay in the game and the visitors were leading until the last minute.

However, the win marks a measure of revenge for Eddie Jones' side, who were beaten in the 2019 Rugby World Cup final the last time these two sides went head-to-head.

England were dominant in the first half and Manu Tuilagi crossed after fine work from Smith opened the play for Henry Slade to make the long pass.

The nerveless Handre Pollard put South Africa on the board prior to Freddie Steward showing great power to bundle over from close range and extend England's lead.

But England's lack of composure at the breakdown meant the lead was only five points at the break, with Pollard nailing three more kicks to Smith's one, and more poor discipline saw South Africa inch ahead thanks to Pollard and Elton Jantjies kicks.

A fine breakaway score from Joe Marchant was answered by an unconverted score from Makazole Mapimpi after Will Stuart was sin-binned, and Frans Steyn kicked another penalty for South Africa.

But Springboks skipper Siya Kolisi saw yellow himself, before another penalty in front of the posts in the final minute allowed Smith to have the final say.

Smith, Steward offer bright glimpse of the future

Smith may only be in the infancy of his international career but he already looks an assured presence at this level.

Full-back Steward put in a fine performance at full-back too. The pair look a very exciting prospect for an England side who played with plenty of attacking intent and backed up a fine win over Australia last time out.

Young front row survives the test but penalties a worry

Much of the narrative ahead of this one was whether the inexperienced duo of hooker Jamie Blamire and prop Bevan Rodd could cope against South Africa's pack.

For the most part they passed the test superbly, but for all their endeavour England were guilty of giving away far too many cheap penalties. On another day, and against a player of the quality of Pollard who hurt them so badly in the World Cup final, it could have been far more costly.

Max Verstappen conceded Red Bull are struggling for pace after a "beautiful" lap from Lewis Hamilton saw the Mercedes driver take pole for the Qatar Grand Prix.

Hamilton, who cut Verstappen's lead in the drivers' championship to 14 points with his victory in Sao Paulo last time out, was quickest on Saturday with a blistering lap of 1:20.827.

Verstappen could not get close to that and was left to settle for second for the first Formula One race in Qatar, the Dutchman finishing 0.455 seconds off the pace.

Valtteri Bottas was third for Mercedes, with Red Bull's setback of Verstappen being unable to get ahead of Hamilton on the grid exacerbated by Sergio Perez failing to make it out of Q2.

Perez will start in 11th, meaning it is Hamilton who has a clear edge going into another crucial race.

Speaking after qualifying, Verstappen said: "[We're] lacking a bit of pace, it's been just a bit more tricky for us, again, in qualifying.

"It just shows we're struggling a bit more than normal. All to play for, but I wish we could have fought for more.

"There's a lot of unknowns, we just need to work on our start and we'll see where we end up."

The difference between Hamilton and Verstappen marked the largest pole margin in dry qualifying this year, with things looking up for the seven-time world champion after a challenging week.

"Yesterday was a really difficult day, Thursday and Friday I wasn't feeling too well, really had to dig deep," said Hamilton.

"I was here until midnight last night, working with the engineers, we found a lot of areas where I could improve. 

"We didn't have any traffic, that last lap was beautiful, this track is amazing to drive.

"I felt fantastic today, slept really well last night, that made a big difference."

Asked about strategy for the race, Hamilton added: "It's not the easiest of circuits to follow, but it's also not massively degrading on the tyres.

"It could be a one or two [stop], we'll find out tomorrow. It's nice and wide into turn one, so we'll be giving everything."

Daniil Medvedev will defend his ATP Finals crown on Sunday following a commanding straight-sets victory over Casper Ruud in the semi-finals.

Reigning champion Medvedev cruised through to the final after wrapping up a 6-4 6-2 win in one hour and 20 minutes in Turin.

The world number two will face Novak Djokovic or Alexander Zverev as he aims to become the ninth different player to successfully defend this title.

Medvedev reached the semi-finals of the year-ending championship with a match to spare, winning three out of three in the Red Group, and did not offer up a single break point against Ruud, who he had beaten in both of their previous meetings.

The US Open champion took early command, breaking in game three and holding before serving to love to take the opening set.

The winner of five ATP Tour titles in 2021, world number eight Ruud was aiming to become the third debutant to lift this trophy in five years after Grigor Dimitrov (2017) and Stefanos Tsitsipas (2019).

However the Norwegian, who squeezed past Andrey Rublev on Friday, was broken twice in the second set as Medvedev surged into a 5-2 lead, before serving out to complete a ninth straight win at this event.

Should Djokovic beat Zverev, it will bring up a fourth meeting of 2021 between the world’s top two players. The Serbian beat Medvedev at the Paris Masters earlier this month and in the Australian Open final at the start of the season, but went down in straight sets at Flushing Meadows in September.

Ruud – 16/26

Collin Sexton will miss the rest of the NBA season after undergoing surgery to repair a torn meniscus, the Cleveland Cavaliers have announced.

The Cavs guard was injured in the 126-109 win over the New York Knicks on November 7 and the severity of the issue has now been confirmed.

A team statement read: "Cavaliers guard Collin Sexton sustained a season-ending left knee injury on Sunday Nov. 7th at New York, later confirmed on Nov. 8th after an MRI administered at Cleveland Clinic Sports Health.

"Sexton underwent successful surgery on Nov. 17th to repair a meniscus tear after additional evaluation over the past week determined that surgery was the best course of action to treat the affected area."

The release added: "His return to basketball activities will be updated as appropriate."

It marks a significant blow for a Cavs team who started the season well but have been hampered by injury issues. Six regulars were unavailable against the Golden State Warriors on Thursday.

Sexton was second for the Cavs in scoring, averaging 16 points before his injury. He was also averaging 3.3 rebounds and 2.1 assists in Cleveland's opening 11 matches.

Tennis star Peng Shuai is safe and well in her own home and will soon "show up in public" to allay concerns about her wellbeing, a leading Chinese state media journalist claimed on Saturday.

Peng has been widely considered to have been missing since making sexual assault allegations against Zhang Gaoli, the ex-vice premier and member of the Chinese Communist Party's Politburo Standing Committee.

Hu Xijin, editor-in-chief of the Global Times, said two-time grand slam doubles champion Peng "didn't want to be disturbed".

Three purportedly new pictures of Peng have been reportedly posted on Chinese messaging app WeChat, along with a "Happy weekend" message.

They show her sitting in a room surrounded by soft toys, lifting up a grey cat, and holding a toy panda. In each of the pictures, which have not been externally verified as being recent, Peng appears to be well and content.

Hu wrote on Twitter: "I confirmed through my own sources today that these photos are indeed Peng Shuai's current state.

"In the past few days, she stayed in her own home freely and she didn't want to be disturbed. She will show up in public and participate in some activities soon."

There have been fears expressed for Peng's safety from within tennis and beyond, and the veracity of subsequent messages from Peng – both on email and posted in her name on Weibo – has been questioned.

There has also been early scepticism expressed about the latest pictures of the 35-year-old.

United States president Joe Biden on Friday called for China to provide "independent and verifiable proof of her whereabouts and that she is safe".

WTA stars Serena Williams and Naomi Osaka are among leading figures to have spoken of their concern for Peng, and men's world number one Novak Djokovic weighed in on Friday, saying he would support any move by the women's tour to back out of events in China.

French sports daily L'Equipe on Saturday led its front page with the question "Ou est Peng Shuai?" – Where is Peng Shuai? – as global concern continued to escalate.

Australia's former doubles world number one Paul McNamee said it was vital that hard evidence is produced to confirm she is safe and well.

McNamee wrote on Twitter: "Peng Shuai, an independent woman of substance, is someone I got to know pretty well. Along with everyone else in the tennis community, I am very worried, as we long to see her and, I reiterate, hear her voice in person."

WTA chairman Steve Simon was quoted on Friday by the BBC as saying his organisation still had not heard from former French Open and Wimbledon doubles winner Peng directly and warned it would have no issue backing out of events in China without proof the player was safe.

The authenticity of an email said to have been sent from Peng this week to the WTA has been questioned, leading Simon to say it "only raises my concerns as to her safety and whereabouts".

Australian Open tournament director Craig Tiley has insisted all players, including Novak Djokovic, must be fully vaccinated against COVID-19 in order to compete at the January grand slam.

Djokovic's vaccination status is unclear, and he has so far refused to confirm whether he has been jabbed, which has led to doubts over whether he will be in Melbourne.

Victorian Premier Daniel Andrews has made it clear that tennis stars arriving for the tournament must be prepared to show proof of having protection against the virus.

For Djokovic, who is competing this week at the ATP Finals in Turin, it remains to be seen whether he is willing to go through that process.

Tiley told Channel Nine: "It's been made very clear, when the Premier announced several weeks ago that in order to participate at the Australian Open, to come into Victoria, you'll need to be fully vaccinated.

"Immediately we communicated that to the playing group, it is the one direction that you take that is going to ensure everyone's safety. All the playing group understands it, our patrons will need to be vaccinated, all the staff working at the Australian Open will need to be vaccinated.

"But when we're in a state where there's more than 90 per cent of the population fully vaccinated, they've done a magnificent job with that, it's the right thing to do."

Tiley said organisers "would love to see Novak" make the trip to a tournament he has won a record nine times.

Djokovic sits on 20 grand slam titles, the same mark as Roger Federer and Rafael Nadal. He needs one more to set the outright men's record, having lost to Daniil Medvedev in the US Open final in September.

"We have been speaking to Novak Djokovic's team and Novak and the team understand clearly that in order to come and play the Australian Open they'll need to be fully vaccinated," Tiley said, according to ABC.

"I know that he wants to play it, he's clearly indicated that and he knows the conditions that he'd have to undergo in order to be eligible to play."

The tournament is due to get under way on January 17, with the player bubbles and quarantine measures that were in force at the 2021 edition no longer in place and Melbourne Park set to operate at full capacity.

Australian player Nick Kyrgios this week said he believes the vaccine mandate is "morally wrong".

Brooklyn Nets head coach Steve Nash believes the referees are to learn how to officiate the NBA's new rules on taking fouls after James Harden had 20 free-throws in Friday's 115-113 win over the Orlando Magic.

Harden starred in the absence of Kevin Durant for the Nets with 36 points including 19 from the line.

The 2018 NBA MVP's form has been down to start the season, with his inability to draw fouls under the new rules seen as partly responsible.

Harden only had 15 free-throws in his first five games this season, but has drawn 43 in the Nets' past three games.

Nash said the uplift in the numbers was a combination of Harden being more aggressive and the referees officiating differently.

"I think both. I think the referees are starting to figure out what's still a foul and what's not a basketball play," Nash said at the post-game news conference.

"I think early it was difficult for them to know what the line was. He's such a difficult guy to over with his size, quickness and ability to shoot over anyone from three.

"Guys have to get too close to him, he's so strong once he gets a slight angle on you or step on you, it's almost impossible not to foul him.

"That's what makes him brilliant, his ability to penetrate and take contact."

Nash was full of praise for Harden, who has scored 35 or more points in two of the Nets' past five games as begins to re-discover his top form.

Harden is averaging 20.3 points, 7.6 rebounds and 8.8 assists per game this season, but he is also averaging 28.4 points from his past five games.

"Great competitiveness, playing for the team, spirit was great," Nash said. "Obviously he can do some playmaking out there. He can attack the basket with his quickness and size.

"He rebounded the ball for us. Huge effort for him everyone pitched in. It was not an easy game for us. we had to find a way to make it happen."

Durant missed the game with a shoulder sprain but Nash said it was not a major concern.

"We don't feel concerned that it'll linger or that he'd miss the next game," he said pre-game.

LeBron James returned from injury but could not prevent the Los Angeles Lakers from suffering their third straight defeat going down 130-108 to the Boston Celtics.

Jayson Tatum starred for the Celtics with 37 points, 11 rebounds and two assists, while Marcus Smart was excellent with 22 points, eight rebounds and six assists.

James had 23 points, six rebounds and two assists on his return from an abdominal strain, while Anthony Davis top scored for the Lakers with 31 points.

The four-time MVP showed no signs of injury in the first quarter, helping the Lakers to a strong start, combining with Davis for 22 points, which was their second most in an opening period in the past two seasons.

The Lakers held the lead at half-time but the Celtics hit back in the third quarter with an 8-0 run, opening up an 11-point lead at the final change after a 33-21 period.

The defeat means the 2020 NBA champions have lost seven of their past 10 games and slip to an 8-9 record, while the Celtics improve to 8-8.

Suns' hot streak continues

Chris Paul had 18 points and 14 assists as the Phoenix Suns secured their 11th straight win, triumphing 112-104 over the Dallas Mavericks, who were without Luka Doncic due to knee and ankle injuries.

Giannis Antetokounmpo had 21 points and 19 rebounds in the Milwaukee Bucks' 96-89 victory over the Oklahoma City Thunder, as Khris Middleton passed Ray Allen for most three-pointers made in franchise history (1,052), hitting three triples in his 16 points.

The Golden State Warriors won without Stephen Curry (bruised hip) and Draymond Green (bruised thigh), with Jordan Poole stepping up with 32 points including four three-pointers in a 105-102 win over the Detroit Pistons.

James Harden shot seven of 25 from the field and had six turnovers but finished with 36 points,10 rebounds and eight assists in Kevin Durant's absence ot lead the Brooklyn Nets past the Orlando Magic 115-113.

Zach LaVine scored 36 points in the Chicago Bulls 114-108 win over the Denver Nuggets who were missing Nikola Jokic, while LaMelo Ball starred with 32 points, 11 rebounds and eight assists in the Charlotte Hornets' 121-118 victory against the Indiana Pacers.

Pelicans clip wayward George 

Paul George shot eight of 26 from the field as the Los Angeles Clippers went down to the New Orleans Pelicans 94-81.

LeBron James says there is a sense of urgency that the Los Angeles Lakers need to play better now after slumping to their ninth defeat of the season on Friday.

James returned from an abdominal strain after eight games out but was unable to lift the Lakers who went down 130-108 to the Boston Celtics.

After 17 games in an 82-game season, the Lakers have an 8-9 record, having lost their past three games and seven of their past 10.

"We damn straight need to play better, no matter who's in the line-up," James said at a post-game news conference. "We have our system and we need to fast-track it and get better with it.

"It's never that we've got 65 games and we can figure it out. There's no level of panic but there should be some sense of urgency every time we hit the floor."

Lakers head coach Frank Vogel said offensively his side needs to "get committed to playing as a team" while he labelled their rebounding (51-33) against the Celtics as "atrocious".

Russell Westbrook was among a host of new players added during the offseason at the Lakers and James said it was taking time for the side to develop cohesion.

The four-time NBA MVP also said patience was required having only just returned, along with starting forward Talen Horton-Tucker.

"As we continue to log more minutes, I continue to see where we're great at and not so good at," James said. "Things that we can improve on.

"Like I said, it's my first game in two and a half weeks. I believe it's Talen third or fourth game back. We're trying to figure out rotations and who to play when."

The Lakers led by eight points at quarter time and held the most slender advantage at the main break, before a 33-21 third quarter.

Vogel added: "We did not have a good third. We were stuck in mud. [But] it's about the whole game more than the third quarter.

"Our group has got to strike the balance of how we're going to play offensively. That's going to take some time. We have to get committed to playing as a team offensively.

"When we do, like we saw in the first quarter, it looks beautiful. You see the potential of what we can be."

James added that recovery from his first game back would be key to his short-term future as he rebuilds following his abdominal strain. The 36-year-old forward finished with 23 points and six rebounds on his return.

"Physically I felt okay. I know I can trust my body and play," he said. "I'm looking forward to seeing how I feel when I wake up. That's the tell-tale sign if I'm moving in the right direction with my injury."

Golden State Warriors head coach Steve Kerr says winning without Stephen Curry was "huge" but offered no update on the two-time MVP's return.

Curry missed Friday's 105-102 victory over the Detroit Pistons having admitted he was nursing a hip contusion after Thursday's 104-89 win over the Cleveland Cavaliers where he shot 40 points.

The 33-year-old point guard has been in MVP-like form this season, averaging 29.5 points, 6.1 rebounds and 6.5 assists per game.

Curry has shot at 41.9 percent from three-point range and averaging a career-high 5.7 three-point attempts made per game.

Curry was joined by Draymond Green on the sidelines against the Pistons, with Andre Igoudala, Otto Porter, Klay Thompson and James Wiseman already unavailable, yet Golden State claimed the win to move to 14-2.

Guard Jordan Poole top scored in Curry's absence with 32 points including four triples, while center Andrew Wiggins contributed 27 points.

"It is a huge win," Kerr said at the post-game news conference. "To win without Steph, Draymond, Andre, Otto and obviously Klay and James are out, so many guys to come in here and really get contributions from everybody.

"I think we're 6-1 now on the road, it's a great sign. I think we've got guys who know how to step up when they need to.

"Wigs and Jordan, knowing they had to score some points for us tonight and be the focal point offensively, they both stepped up."

The Warriors return home for Sunday's game against the Toronto Raptors, although Kerr did not confirm if Curry or Green would play.

"We'll see. We'll see," Kerr said. "We have tomorrow off. The guys who are injured [will] come in and get treatment tomorrow and then we have a five o'clock game, so no shoot-around Sunday.

"We'll see how everyone is doing on Sunday."
