Philadelphia 76ers head coach Doc Rivers said the Ben Simmons drama is muting the fun of opening day for the NBA title contenders.

Simmons will not feature in Wednesday's opener against the New Orleans Pelicans – the three-time All-Star suspended by the 76ers due to "conduct detrimental to the team" following reports he was ejected from practice after Rivers grew frustrated with his lack of engagement.

76ers guard Simmons has demanded a trade amid criticism following last season's shock playoff exit to the Atlanta Hawks and was absent from Philadelphia for the first two weeks of preseason work before showing up on October 11 to begin fulfilling COVID-19 protocols that would allow him to re-join the championship-chasing franchise.

Speculation over Simmons' future is now set to intensify amid reported interest from the likes of the Minnesota Timberwolves, Cleveland Cavaliers, Golden State Warriors, San Antonio Spurs, Houston Rockets, Portland Trail Blazers and Indiana Pacers.

Ahead of the 76ers' clash with the Pelicans, Rivers told reporters: "It's a predicament that we're in and that part is no fun. It really isn't.

"We get to play right now and Ben is not. I want Ben to be playing. That's his job."

Simmons – an elite defender who signed a five-year, $177.2million contract extension in 2019 – and his shooting problems were laid bare during the 2021 postseason with the top-seeded 76ers, who were eliminated in the semi-finals.

The 25-year-old had no fourth-quarter field-goal attempts in his last four games of the playoffs against the Hawks last season. He is the only NBA player in the last 20 seasons to have four consecutive postseason games with no field-goal attempts in the fourth quarter during a season in which he was an All-Star, according to Stats Perform.

Simmons averaged just 10.1 field-goal attempts in 2020-21 – a career low, which dropped to 7.9 in the playoffs. It was the same story with his scoring as it dropped to a career-worst 14.3 points per game and 11.9 in the postseason – both career lows.

Then there is Simmons and free throws. He was exposed by rival teams as they regularly sent him to the line, with the Melbourne-born guard making just 25 of 73 shots in the 2020-21 playoffs. His 34.2 free-throw percentage is the lowest ever in a single postseason.

"Obviously you don't want any of those things. You get a lot of texts, 'great job' and all this stuff and it's not," Rivers said. "I don't think people understand ... you want all your players to do well.

"You cheer for your players. Even when they're in a tough spot, you want it to go well for them, you do. When you're put in positions like [Tuesday], it's no fun."

Philadelphia – who finished with the best record in the Eastern Conference last season – have won five of their last six games against New Orleans, though the Pelicans claimed their last home meeting. Of those six games, five were decided by seven or fewer points.

Seth Curry shot 45.0 per cent from beyond the arc for the 76ers last season – his third consecutive campaign shooting at least 45.0 percent from three-point range, all with different teams. He is the fourth qualified player in NBA history with three straight seasons of 45.0-percent shooting from downtown, according to Stats Perform.

Karen Khachanov revealed he felt the nerves of playing in front of a home crowd as he marked his return to Moscow with a comeback victory in the Kremlin Cup.

Handed a bye for the opening round, third seed Khachanov made home advantage count in his first match as the Russian defeated Australian world number 50 James Duckworth 3-6 6-3 6-1 to reach the quarter-finals on Wednesday.

Khachanov – Olympic Games silver medallist, who triumphed in Moscow three years ago – will face another Australian, John Millman after he defeated Illya Marchenko 6-1 5-7 6-4 at the ATP 250 tournament.

"It always feel great to be back in your hometown, in a tournament where everything started for me as a professional tennis player," world number 31 Khachanov said.

"[This is] where I won my first matches, I got my first points. Since then, it's always great to come back home to see a crowd, [get] home support. It's also little bit more nervous, of course. But I always enjoy playing at home."

Khachanov was joined in going through to the last eight by sixth seed Marin Cilic – a two-time Kremlin Cup champion who overcame Tommy Paul 7-5 6-3.

At the European Open in Antwerp, top seed Jannik Sinner downed fellow Italian youngster Lorenzo Musetti 7-5 6-2 in the duo's first meeting as professionals.

"We never practice together, so it was kind of a new match," Sinner said post-match.

"He's an incredible player. He's a very great talent, so I hope we will have a couple of more matches on the pro tour, and obviously I'm very happy about my level today."

Arthur Rinderknech upstaged eighth seed Dusan Lajovic 6-3 4-6 6-2 to set up a quarter-final tie with Sinner, who is in the hunt for a fourth title of the season and a place at next month's ATP Finals in Turin.

Another emerging talent, qualifier Jenson Brooksby, bettered US Open quarter-finalist Botic van de Zandschulp 6-2 6-0, with Alejandro Davidovich Fokina sending third seed Cristian Garin packing 4-6 6-3 6-3.

Aryna Sabalenka edged past Ajla Tomljanovic in the Kremlin Cup to reach the quarter-finals in her first match since contracting COVID-19 after the US Open semi-finals. 

Top seed Sabalenka – appearing in Moscow for the first time – had not played since being downed by Leylah Fernandez, having tested positive for coronavirus on the eve of the Indian Wells Open. 

The Belarusian, who sits second in the world rankings, profited from a bye in the first round before battling past Tomljanovic 7-6 (7-2) 4-6 6-1 on Wednesday as she fired 10 aces but made 30 unforced errors. 

Sabalenka will now meet Ekaterina Alexandrova after the Russian cruised past Anhelina Kalinina 6-4 6-1, while Anastasia Pavlyuchenkova comfortably defeated Bernarda Pera 6-2 7-5. 

Number two seed Garbine Muguruza also reached her seventh quarter-final of the season as she defeated Tereza Martincova 6-4 4-6 6-3 in just under three hours in Moscow. 

Meanwhile, Elina Svitolina was shocked in the Tenerife Open as she was dumped out by Maria Camila Osorio Serrano, who succeeded 5-7 6-3 6-2 to claim her first top-10 victory. 

Svitolina was the favourite in Spain and comfortably took the first set on Tuesday. However, inadequate light stopped play and the 19-year-old Osorio responded emphatically the following day to secure a memorable triumph. 

Ann Li coasted past Varvara Gracheva 6-4 6-2 after Anna Karolina Schmiedlova had dispatched Jaqueline Cristian 6-2 7-5 in the opening match of the day. 

Xinyu Wang retired injured against Alize Cornet, who led 4-1 in the decisive set, while Donna Vekic and Irina-Camelia Begu's match was suspended for bad light with the Croatian leading by a set. 

Ole Gunnar Solskjaer was "sure" Manchester United would beat Atalanta after match-winner Cristiano Ronaldo completed a dramatic Champions League comeback on Wednesday.

Ronaldo was the hero again at Old Trafford, where United overturned a two-goal deficit to stun visiting Atalanta 3-2 on matchday three in Group F.

United trailed 2-0 before the half-hour mark in Manchester after Mario Pasalic and Merih Demiral shocked the Theatre of Dreams.

Reeling after a 4-2 Premier League defeat at Leicester City last time out and just two wins in their previous seven games, the Red Devils were given a glimmer of hope when Marcus Rashford pulled a goal back eight minutes into the second half – the club's 300th strike in all competitions under Solskjaer.

United captain Harry Maguire equalised with 15 minutes remaining before superstar Ronaldo stepped up to complete the fightback nine minutes from time.

On what he said at half-time, Solskjaer told BT Sport: "I said make sure we get the next goal, because then we win the game.

"As long as we don’t concede I was pretty sure we would win the game. It was just about taking chances."

"I thought we played well first half too. Two chances, two goals. It had to stop if we are to survive," Solskjaer said after United rallied from two or more goals down for the third time – no side has done so more often in the Champions League.

"We have a habit of doing this at this club. I thought we played well and they scored a goal out of nothing and then another set-piece. But they never stopped believing and kept going."

"The fans are a big, big part of this club," Solskjaer added. "The singing section here today kept the players going in their belief. That is what you do at Manchester United on a Champions League night."

Solskjaer defended Ronaldo following some criticism that he does not work hard or defend enough for the Premier League giants.

Ronaldo has now scored in three consecutive Champions League games for United for the second time – the 36-year-old five-time Ballon d'Or winner previously doing so in November 2007 en route to lifting the trophy with the Red Devils.

“If anyone wants to criticise him for work rate or attitude, just look at the way he runs around in this game," he said.

Solskjaer has found himself under growing pressure amid United's poor form and performances and when it was put to him whether the squad had played for him midweek, the Norwegian responded: "Don't disrespect the players.

"They played for Man United and they are the luckiest men in the world because they're the ones who get to play for Man United and millions of boys and girls would love to do that."

Gerard Pique scored the only goal as Barcelona beat Dynamo Kiev 1-0 at Camp Nou to get off the mark with their first victory in this season's Champions League.

Barca had lost their opening two group games for the first time ever, going down 3-0 to both Bayern Munich and Benfica, but they were good value for the three points.

Pique volleyed in a first-half opener to end a run of 287 minutes without a goal in the competition for the Catalans and they looked comfortable without adding to their scoring.

The win moves Ronald Koeman's men above Kiev into third place in Group E, a point behind Benfica and three off Bayern Munich, with those two sides meeting later on Wednesday.

Barca had recorded fewer shots on target (one) than any side in the competition heading into gameweek three and that lack of cutting edge was again on show as Sergino Dest failed to test Georgi Bushchan with a close-range header early on.

Luuk de Jong was also off target with a headed attempt from six yards, though the striker did at least manage to force Bushchan into a first save three minutes later with a curled shot from the edge of the box.

The hosts' breakthrough duly arrived through Pique with 36 minutes played, the centre-back being left in space to guide in Jordi Alba's latest exquisite cross with a first-time finish.

Ansu Fati, brought on for the ineffective De Jong at half-time, wasted a good chance to score Barca's second when getting his angles all wrong and sending an overhead kick wide of the target.

Barca could not fashion any more opportunities, but the Ukrainian champions failed to ask any questions of their opponents, not registering a single shot on target as Pique's goal proved the difference.

Gianni Infantino hinted FIFA is prepared to dial back on plans for a biennial World Cup and says hosting its premier international tournament in a single nation is a "thing of the past".

FIFA, led by chief of global football development Arsene Wenger, had been promoting the idea to change the World Cup format and proposed the tournament takes place every two years.

Wenger's proposal would see a major tournament held every year, however, UEFA and CONMEBOL quickly retaliated, vocally opposing the plans and expressing scheduling concerns.

Speaking after a FIFA council meeting, president Infantino announced he would convene with football's governing bodies on December 20 to debate any potential football calendar reforms once again.

However, Infantino refused to commit to holding a vote on any of the proposals as he suggested the divisive plan would have to benefit all stakeholders.

"We have to see how we can approach the different opinions of different parties," Infantino told reporters on Wednesday. 

"We need to look at sporting and economic merits, then we can have a reasoned discussion about World Cups and perhaps other competitions. 

"I do not know what the outcome will be. We will continue with the objective of reaching a consensus with solutions that work for everyone's benefit. 

"By hosting a global summit later this year, we will now have the opportunity to present one plan and to provide feedback to all our FIFA member associations."

The 2026 World Cup is set to be hosted by Mexico, Canada and the United States, and Infantino also revealed his preference for multi-nation bids hosted by a continent, as opposed to a single country.

When asked about the possibility of South Americans co-hosting the 2030 edition, Infantino responded: "The World Cup is the biggest competition, the biggest event on earth, and several countries would like to organise a World Cup. 

"I myself as FIFA President am very interested to hear the continent is interested in hosting the World Cup, there is so much passion in South America for football. Everybody would like to see a new World Cup in South America.

"You mentioned Brazil, and I think that World Cups held in one single country are probably a thing of the past.

"I think probably we'll see more World Cups held by two or three different countries. If we do so, every region in the world can not only dream, but really plan to organise a World Cup."

Cleveland Browns quarterback Baker Mayfield has been ruled out of their clash with the Denver Broncos.

Mayfield is dealing with a torn labrum in his left shoulder but had previously insisted he would be fine for the visit of the Broncos.

However, his streak of 51 consecutive starts will come to an end as the Browns look to improve to 4-3 on the season.

Instead, Case Keenum will get the start under center.

"We have full confidence in him [Keenum] to lead us and do the things necessary to put us in position to win," Browns coach Kevin Stefanski said.

"Baker fought really hard to play, he's a competitor and obviously wants to be out there but just couldn't make it on a short week.

"We know he will continue to do everything in his power to return as quickly as possible."

In addition to Mayfield, the Browns will be without both of their starting running backs.

Nick Chubb will miss his second successive game because of a calf injury, with Kareem Hunt having been placed on injured reserve with a similar issue.

The Browns could again be minus both of their starting offensive tackles, Jack Conklin and Jedrick Wills, while wide receiver Odell Beckham Jr. sat out Tuesday's practice because of a shoulder issue.

Having dropped successive games to the Los Angeles Chargers and the Arizona Cardinals, the deck could be stacked against Keenum in his bid to help the Browns avoid another damaging defeat.

Pohang Steelers came from behind to book their AFC Champions League final spot with a 5-4 penalty shootout victory over 10-man Ulsan Hyundai after a 1-1 draw.

Alex Grant nodded in a late equaliser before Pohang scored each of their five penalties, with Davy Bulthuis missing for Ulsan.

A cagey first half saw just two clear-cut chances, with Lee Seung-mo heading against the left post in the sixth minute for Pohang before Ulsan should have gone ahead on the stroke of half-time as Yun Il-lok headed a free-kick wastefully wide after being found unmarked at the back post.

The deadlock was broken seven minutes after the restart when Yoon Bit-garam's low ball across the face of goal was spilled by Jun Lee, allowing Yun to pounce on the loose ball and fire in from close range.

Pohang threw men forward in search of an equaliser but were nearly caught out as Yoon struck the right post from Lee Dong-gyeong's cutback, with Lee Jun rooted to the spot.

Ulsan were reduced to 10 men as captain Won Du-jae slid in on Lim Sang-hyub with his studs showing, earning himself a straight red card with over 20 minutes of normal time still to play.

The Ulsan midfielder's error of judgement proved costly as Pohang's man advantage paid dividends, with defender Grant heading in off the post in the top-right corner to level the scores with one minute of normal time remaining, forcing extra-time and then spot-kicks.

Ulsan centre-back Bulhuis was the only player to miss from the spot, blazing over the bar, although Lee Chung-Yong saw a tame stutter-stop effort easily saved, but was allowed to re-take it as Jun Lee was off his line.

Pohang scored all five spot-kicks, with captain Kang Sang-woo rifling the final penalty inside the left-hand post to spark wild celebrations.

The K League 1 side will face Saudi Arabian outfit Al Hilal in the final on November 23.

Lewis Hamilton will look to bounce back from frustration in Turkey as he returns to one of his favourite tracks at the United States Grand Prix this week.

The drivers' championship battle between Hamilton and Max Verstappen continues to be closely fought, with just six races left in the 2021 season.

Red Bull driver Verstappen moved back into the lead in Istanbul and comes to Austin with a six-point advantage over Hamilton, who is seeking a record-breaking eighth world title.

Hamilton took an engine penalty in Turkey and limited the damage to his rival, but was frustrated with his own team over a strategy call that he felt may have cost him a podium.

The trip to the USA therefore comes at a good time for the Briton, who has won this race a record six times.

Only in Hungary, Great Britain (both eight) and Canada (seven) has Hamilton won more times and he did not have the chance to add to his tally in 2020 as the event was not held due to the coronavirus pandemic.

Hamilton has eight podiums from his nine USA races, and the only time he did not make the top three he still finished fourth in 2013.

He also sealed the third and sixth of his seven world titles in Austin, his 2015 race win and second-place finish in 2019 giving him those successes.

While Verstappen leads the drivers' battle, Mercedes do still top the constructors' standings and will hope a resurgent Valtteri Bottas can help Hamilton to continue the team's strong track record at the venue.

LAST TIME OUT

Strategy was key in wet conditions at the Turkish Grand Prix, with Hamilton left frustrated by Mercedes' decision to pit late and help Verstappen, who ended up in second place, reclaim the championship lead.

Having been fastest in qualifying but handed a 10-place grid penalty due to his engine change, Hamilton saw team-mate Bottas start in first place.

It was a lead Bottas only relinquished briefly to Charles Leclerc, though the Finn regained it with a brilliant move on the inside of the Ferrari with 11 laps remaining to claim his first win of the season.

Hamilton's decision to hold off pitting in the wet conditions was what prompted debate between driver and the Mercedes pit wall.

Well in the hunt for a podium place in the 51st lap, Hamilton was finally instructed to come in which meant he was forced to settle for fifth behind Bottas, Verstappen, Sergio Perez and Leclerc.

WHAT TO EXPECT IN USA

Hamilton's fine record in the United States means it is he who goes into the race weekend as the narrow favourite to strike the next blow in a thrilling title battle on Sunday.

Verstappen has solid form at the Circuit of the Americas too, though, with past finishes of second, third and fourth.

The Dutchman is optimistic of taking the fight to Mercedes as he targets a first Austin win, as he looks to end a run of three races without a victory in 2021.

That title race will again be the main focus, with both Mercedes and Red Bull hoping their second drivers can get in on the action to help Hamilton and Verstappen respectively.

Bottas claimed his first win of the year last time out and has three podiums from his last four outings, while Perez finally ended a miserable eight-race run without a top-three finish in Turkey.

Lando Norris is one point away from matching his total from the 2019 and 2020 seasons combined and will hope McLaren can be more competitive this week. 

They are locked in a close battle with Ferrari for third place in the constructors' championship, with the British team just 7.5 points ahead of their Italian rivals.

TOP FIVE OPTA FACTS

Qualifying key - The past 10 winners of the United States Grand Prix came from the first row of the grid - six from pole position and four from second place.

Fond memories – The last time F1 raced in the United States (2019), Hamilton reached his 150th career podium. He has since moved on to 176 top-three finishes, an F1 record total.

Bottas barrier – The Finn is looking to get a pole position and race win double in consecutive grands prix, a feat he has never achieved before. He did get pole and win the race at the 2019 edition of this event. 

Mercedes mark – The team have six poles in their last six races in the United States and another here would see them equal Ferrari on seven poles in the country. Only Lotus (10) have recorded more than Ferrari.

Austin aces – Mercedes have had a podium finisher in each of the last six USA races, winning five of those events and finishing with a one-two in four of them, including the last one in 2019.

Australian Minister for Immigration Alex Hawke insists Novak Djokovic would need to be fully vaccinated against COVID-19 in order to enter the country and defend his Australian Open title.

The Serbian is the top-ranked player in the world and could move clear of Rafael Nadal and Roger Federer for grand slam titles if he can claim his 21st at Melbourne Park.

However, Hawke's comments regarding vaccination requirements cast doubts over Djokovic's participation, with the 34-year-old previously declining to reveal his vaccination status.

"You'll need to be double vaccinated to visit Australia," Hawke said to Australian Broadcasting Corporation radio. "That's a universal application, not just to tennis players. I mean that every visitor to Australia will need to be double vaccinated.

"I don't have a message to Novak. I have a message to everybody that wishes to visit Australia. He'll need to be double vaccinated."

With recent reports suggesting that over a third of professional players have yet to be fully vaccinated, a significant number could be denied the chance to play in the opening grand slam of 2022.

The men's ATP and women's WTA tours have attempted to encourage players with reservations to get the vaccine, and Tennis Australia explained that it was working with government authorities regarding conditions for the tournament.

"Our understanding is that the details around international visitors entering the country are yet to be decided and we hope to have more information soon," Tennis Australia said in a statement.

Australia's health minister Greg Hunt defended the ruling, explaining that the decision had been taken with the safety of the country's citizens in mind.

"The [rules] apply to everyone without fear or favour," Hunt said. "It doesn't matter whether you are number one in the world or you are anything else."

Djokovic, who withdrew from the Indian Wells Masters this month, has won nine of his majors at the Australian Open.
