NBA champions the Milwaukee Bucks confirmed two-time All-Star Khris Middleton has tested positive for coronavirus.

Middleton had missed Sunday's 107-95 loss to the Utah Jazz with "illness" and was again absent from the Bucks team to play the Detroit Pistons on Tuesday.

Bucks head coach Mike Budenholzer, who had said after the Jazz defeat that the illness was not COVID-related, confirmed prior to the Pistons clash Middleton had since entered the NBA's health and safety protocols.

"We thought he just had a head cold or some type of non-COVID illness," Budenholzer told reporters. "And then, [he] didn't feel good again the next day. Got tested and has come back positive."

The Bucks, who have lost three consecutive games to slip to a 3-4 record, are already missing Jrue Holiday (ankle), Donte Divincenzo (ankle) and Brook Lopez (back).

Under the NBA's health and safety protocols, Middleton must sit out for 10 days minimum, meaning he may miss more than seven games stretching until next Friday's battle against the Boston Celtics.

"It's a challenge to figure out who's available, to get the best groupings out there and how we can get through a game and not really wear down the guys that are healthy," Budenholzer said.

Middleton becomes the third NBA player to test positive to COVID-19 this week, following Philadelphia 76ers forward Tobias Harris and Cleveland Cavaliers forward Kevin Love.

The Tokyo Olympics gold medallist averaged 20.4 points, 6.0 rebounds and 5.4 assists across the Bucks' title-winning 2020-21 season.

Milwaukee have failed to lead at any point in three different games this season, including their loss on Sunday per Stats Perform. Last season, the Bucks held a lead in all 72 of their games.

The Bucks have won 10 straight games against Detroit – tied for Milwaukee's longest active win streak against any opponent (also the Sacramento Kings). It is also the longest win streak by either team in the series history.

Belinda Bencic fought back to beat Angelique Kerber in a blockbuster showdown and help Switzerland eliminate Germany on day two of the Billie Jean King Cup in Prague.

Germany lost to hosts Czech Republic on the opening day and were brushed aside 3-0 by Switzerland on Tuesday, with world number nine Kerber losing 5-7 6-2 6-2 to Bencic.

Kerber was carrying an injury and was outlasted by the Olympic gold medallist, with that triumph coming after Viktorija Golubic defeated Andrea Petkovic 6-4 7-5.

Golubic and Jil Teichmann added further gloss to the scoreline by overcoming Anna-Lena Friedsam and Nastasja Mariana Schunk in the doubles.

Switzerland will now meet the Czech Republic in a winners-takes-all contest to determine who finishes top of Group D.

The upset of the day came in Group B as Australia beat Belgium 2-1, with Daria Gavrilova kicking things off by beating Greet Minnen 6-4 1-6 6-4.

Storm Sanders then battled back to beat Elise Mertens 4-6 7-6 (7-5) 6-0, rendering Mertens and Minnen's doubles win nothing more than a consolation. 

In Group A, Russia cruised to a 3-0 win over Canada.

Daria Kasatkina beat Carol Zhao 6-3 6-1 and Anastasia Pavlyuchenkova was too strong for Rebecca Marino as she prevailed in three sets.

Slovakia top Group C, meanwhile, after beating the United States 2-1. Shelby Rogers fell 6-4 6-4 to Viktoria Kuzmova before Danielle Collins levelled with a 6-3 6-2 win against Anna Karolina Schmiedlova.

That set up a decider in the doubles, which went the distance as the Slovakian pair of Kuzmova and Tereza Mihalikova prevailed 6-2 6-7 (5-7) 12-10 in a thriller with Caroline Dolehide and CoCo Vandeweghe.

Novak Djokovic recovered from a second-set blip to emerge victorious 6-2 4-6 6-3 in his first match since the US Open at the Paris Masters.

Victory in Paris would see Djokovic – competing for the first time since September's loss to Daniil Medvedev in the Flushing Meadows final – clinch the year-end number one ranking for a record seventh time.

Djokovic looked to be on course for a routine victory to start his campaign after comfortably taking the first set against Marton Fucsovics in their second-round contest on Tuesday.

However, the top seed's Hungarian opponent fought back to force a decider, hitting 13 winners to seven unforced errors in the second set.

But Djokovic – a record five-time Paris Masters champion – ensured a remarkable turnaround was not forthcoming, breaking Fucsovics twice in the third and, after letting one match point slip, clinching his second to secure victory.

Felix fights back

Ranked 12th in the ATP Race to Turin, Felix Auger-Aliassime needs to lift the trophy in Paris and hope Casper Ruud and Jannik Sinner do not reach the latter stages to make it to the ATP Finals.

Auger-Aliassime risked falling at the first hurdle on Tuesday as the ninth seed was forced to fight back to defeat Gianluca Mager 4-6 6-4 6-1.

"I had difficulty with my pace at the beginning of the match," said Auger-Aliassime. "I didn't hit enough first serves so I had a bit of pressure on my second serve.

"So I could have served better in the first set. I [had] a poor game at four-all and I got broken, but even before that there were moments at 30-all it was a bit hot and a bit tight. I think I relaxed. I found a better pace at the beginning of the second set, and it went even better as the match went forward."

He will next face Dominik Koepfer in the second round following the German's stunning win over Andy Murray on Monday.

Alcaraz sets up Sinner clash

Sinner will have an extremely testing second-round clash after Carlos Alcaraz came from behind to see off wild card Pierre Hugues-Herbert.

Alcaraz let slip a 4-2 lead in the first set to lose that on a tie-break but won six straight points in a second-set breaker before eventually battling to a 6-7 (4-7) 7-6 (7-2) 7-5 win in two hours, 53 minutes.

"It's not easy to play against a home player," Alcaraz said. "I think we played a good level and it was a great match, so I am happy to win. He has a great serve, so I had to return better and remain focus. I think that was the key. I am playing at a good level and I want to finish the year strong."

Diego Schwartzman – the 11th seed – needed three sets to see off John Millman, 15th seed Gael Monfils reversed a one-set deficit against Miomir Kecmanovic and 16th seed Grigor Dimitrov survived a three-setter with Richard Gasquet.

But one seed did fall on Tuesday, Roberto Bautista Agut (14) edged by James Duckworth in three sets.

The new NBA season is two weeks in and narratives are already forming.

The Golden State Warriors are back, the Chicago Bulls' rebuild was a success, and several top teams – including defending champions the Milwaukee Bucks – are toiling.

Those themes may not hold for the entire regular season, but we have now seen enough to recognise some patterns – and the same is true on an individual level.

Which players have made flying starts to this campaign, and which are yet to find their feet? Stats Perform takes a look with the first 2021-22 edition of NBA Heat Check.

RUNNING HOT...

Miles Bridges

The Charlotte Hornets were already a fun watch last year thanks to LaMelo Ball, but the second-year point guard has help in 2021-22. Bridges has been one of the key men in lifting the Hornets to an exciting 5-3 start.

Playing alongside Ball, Gordon Hayward and surprise 2020-21 star Terry Rozier, Bridges leads Charlotte in scoring with 23.1 points per game. Now in year four, his previous best had seen 13.0 in his sophomore season.

Bridges' shooting from the field (47.2 per cent) and from three-point range (34.4 per cent) is actually down on last year, while he is only marginally more accurate from the foul line (88.2 per cent).

But the forward is thriving on having been given increased responsibility this season. He is back to being a regular starter, up to 35.5 minutes per game from 29.3, and attempting almost twice as many shots. Through Monday's games, only seven players in the NBA had attempted more shots from three (61).

With assists (3.4), rebounds (7.9), steals (1.8) and blocks (0.9) also on the rise, the Hornets could have a major asset if Bridges maintains these standards.

Ja Morant

If Bridges' development has represented a major shock, Morant's has not. The Memphis Grizzlies sensation was the Rookie of the Year two seasons ago and dumped the Warriors out in the play-in round last year.

Still, Morant's performances have been mightily impressive. His 28.3 points per game trail only Stephen Curry and Paul George. Having played more games than both, his 198 total points lead the league. Morant also tops the charts for field goals made (75).

After a 2-0 start, Morant had 40 in a losing effort against the Los Angeles Lakers and soon added 30 against the Warriors to return the Grizzlies to winning ways.

The 22-year-old is certainly not the finished article – only Russell Westbrook has had more turnovers than his 34 and a plus/minus of -6.1 suggests his scoring is not making up for shortcomings in other areas – but the rate of improvement indicates Memphis will be rewarded soon enough for sticking by their man.

Harrison Barnes

Barnes has seen what elite looks like, having been drafted by the Warriors in 2012 and started every game across the regular season and playoffs when they won the title three years later.

But Barnes was merely the fourth or fifth scoring option on that team and, through moves to the Dallas Mavericks and then the Sacramento Kings, has taken time to establish himself as a leading man.

This could well be the year, though. Barnes is the Kings' top scorer with 23.3 points per game, boosted by a career-high 36 against the Portland Trail Blazers on opening night.

Perhaps unsurprisingly, the forward's scoring output has fallen with each passing performance since that stunning display, but he is bringing more to Sacramento than just scoring. Last year's 6.6 assists were a career high, only to be topped by a staggering 10.3 this time.

Although Barnes' Kings team-mates suggested after the Portland game they were always confident he could produce such displays, his progress at 29 has come as a surprise to everyone else.

GOING COLD...

Damian Lillard

Numerous players have explained away their below-par outputs by complaining about the NBA's new interpretation of the foul rule this season – a "change in the officiating of overt, abrupt or abnormal non-basketball moves by offensive players with the ball in an effort to draw fouls" essentially meaning fewer trips to the foul line for certain stars.

Trae Young, one of those prominently affected, named Lillard as another who was suffering more than usual.

Lillard is attempting only 3.9 free throws per game this year, in line with his career-low rookie year. His 18.6 points are below 19.0 he offered the Blazers in 2012-13. He had 28.8 last season.

But those foul calls are not Lillard's only issue, with his shooting from the field also hugely underwhelming through seven games.

The point guard is making only 34.9 per cent from the field and, having previously scored 4.1 three-point attempts per game, 23.1 per cent from beyond the arc. Those are also career lows and sources of major concern for Portland.

Dwight Howard

The Lakers made significant changes to their roster in the offseason and a number of the new recruits have not yet hit their stride.

It figures that Westbrook, now the third man in LA, should have seen his points (18.3), assists (8.7) and rebounds (8.7) take a hit along with his usage rate (28.5 per cent) after averaging a triple-double on the Washington Wizards, but Howard's slow early-season form was less predictable.

The three-time Defensive Player of the Year played a key bench role in the Lakers' title success in 2019-20, even starting seven playoff games, before joining the Philadelphia 76ers for a season.

Back at Staples Center, Howard is proving far less effective to this point. Both his points (4.3) and, most concerningly, rebounds (4.0) have reached career lows. His minutes are down from 17.3 last year to 15.2 this, but his averages per 48 only further display a decrease in performance – 23.3 rebounds becoming 12.7.

With Howard also involved in an altercation with Anthony Davis during a defeat to the Phoenix Suns, it is fair to say his Lakers return has not so far gone entirely to plan.

Babar Azam claimed "everything has gone to plan" after Pakistan sealed their T20 World Cup semi-final spot with victory over Namibia on Tuesday.

Captain Babar and Mohammed Rizwan combined for their second 100-opening stand of the tournament, leading Pakistan to 189-2 – the second-highest score in the competition so far.

Namibia – led by David Wiese (43 not out) and George Williams (40) – batted impressively in their response but could still only muster a 45-run loss against the 2009 champions, who have now won all four of their opening games.

Despite a few misdemeanours in the field, Babar was left satisfied with yet another efficient performance from his side as they became the first team to officially confirm their place in the final four.

"It was a different plan today, we wanted that opening partnership to go deep and it worked for us," Babar said at the post-match presentation.

"We then had two good players in [Mohammed] Hafeez and Hasan Ali. They'll be important in the next stage and it was important we ticked those boxes [scoring runs at the end, batting first].

"There was some dew that didn't help with the fielding, but that's not an excuse, we need to be better.

"Everything has gone according to plan. We're looking forward to the semi-finals and playing our cricket with the same intensity."

Pakistan sit on eight points at the top of Group 2, with Afghanistan currently in second on four points.

In Group 1, England have all but qualified with four wins in four games, with South Africa – Pakistan's potential semi-final opponents – on six points in second, two clear of third-placed Australia.

Dominic Thiem has confirmed he has been given a coronavirus vaccine and will return to action in Abu Dhabi next month with the objective of playing in the 2022 Australian Open.

The 2020 US Open champion has been out of action since suffering a wrist injury at the Mallorca Championships in June.

Thiem on Tuesday revealed he has made good progress with his recovery and will play in the World Tennis Championship, an exhibition event that will be staged from December 16-18.

The 28-year-old had stated he wanted to wait for a Novavax jab, but was urged by Austrian minister for Social Affairs, Health, Care and Consumer Protection Wolfgang Muckstein to take an alternative vaccine as his preferred choice would not be available until next year.

Thiem says he has now been vaccinated and is relishing getting back on court as he eyes a grand slam return in Melbourne in January.

"I am very happy to announce that my recovery is going well. The MRI I did today showed that my wrist injury has improved significantly," Thiem tweeted on Tuesday.

"A couple of weeks ago I started playing with soft balls and was able to switch to normal tennis balls during yesterday's practice session. My team and I strongly believe that I'll be ready to make my comeback later this year.

"I'll be returning to competition in December and will be playing the MWTC 2021 in Abu Dhabi – with the objective to return to the Tour for the 2022 Australian Open.

"Needless to say that the vaccine is needed to play both events, and in my case I have already been vaccinated. I saw recently some news about this and I had to make it very clear that I would get vaccinated. Hopefully the next time things won't be taken this far [sic] as I saw last week..."

Rafael Nadal is also set to return from injury in Abu Dhabi.

Odell Beckham Jr's father is not happy with the Cleveland Browns wide receiver's numbers this season, and a famous fan shares that sentiment.

Ohio native LeBron James took to Twitter to voice his frustration at Beckham's production, though, like the wideout's father, he appears to not blame the man himself.

The four-time NBA MVP posted on Tuesday: "OBJ will show again why he's special. WR1 #FreeOBJ."

That tweet followed an Instagram post from Odell Beckham Sr featuring an 11-minute video showing clips of Browns quarterback Baker Mayfield eschewing chances to throw to an open Beckham.

The social media posts came on the day of the NFL's trade deadline, but Beckham is not among the players expected to be moved despite his struggles.

Beckham has 17 catches for 232 yards and zero touchdowns for the Browns since returning from a torn ACL in Week 3.

Those numbers have been somewhat impacted by a shoulder injury to Mayfield, who missed the Browns' Week 7 win over a Denver Broncos because of a torn labrum but returned on Sunday for Cleveland's 15-10 loss to the Pittsburgh Steelers.

Newcastle United have been warned Unai Emery is enjoying life at Villarreal after he was linked with the newly-wealthy Premier League club.

Former Arsenal and Paris Saint-Germain boss Emery is said to be a prime target for Newcastle, whose new Saudi majority owners are seeking a successor to Steve Bruce.

According to reports in England on Tuesday, Emery and former Bournemouth manager Eddie Howe have both been considered for the job at St James' Park. Newcastle are said to want Emery in place before Saturday's game against Brighton and Hove Albion.

Whether Emery is tempted by a return to the Premier League remains to be seen, after he endured a difficult time with Arsenal. He would be inheriting a team who are facing a relegation battle, albeit he would likely have substantial funds for new signings in January.

Villarreal faced a Champions League home game on Tuesday evening against Young Boys, with Emery's future suddenly clouded in doubt.

Yet Emery, who turns 50 on Wednesday, is content with his current position, according to LaLiga club Villarreal's president Fernando Roig.

Roig told Spanish broadcaster A Punt Media: "Emery is very happy in Villarreal and has a contract in force."

The president said it "is not a decision for Villarreal" should Newcastle be willing to pay up his release clause.

Emery was asked about the Newcastle link on Monday, and said: "The truth is that I don't know anything."

Bruce was an early casualty of the new regime, with the club seeking a big-name boss to lead them into a fresh era.

Emery won three successive Europa League titles with Sevilla before leaving in 2016 and spending two years at PSG, where he continued to stack up trophies.

The trophies dried up at Arsenal, where he was the man chosen in 2018 to take over from long-serving Arsene Wenger. Emery was sacked in November 2019, after 18 months with the Gunners, but returned to coaching with Villarreal and helped the Spanish club win last season's Europa League title, beating Manchester United after a marathon penalty shootout.

That secured a Champions League place for this season, with Villarreal sitting second in Group F after three games heading into Tuesday's round of matches.

Their domestic league form in 2021-22 has so far left a little to be desired, however, with Villarreal winning just two of their opening 11 games in LaLiga, drawing six and losing three, to sit 13th.

Pep Guardiola urged former Manchester City striker Sergio Aguero to prioritise his health and be careful in his recovery from treatment for a suspected cardiovascular problem.

Aguero, who ended a 10-year spell with City at the end of last season, had to be substituted during Barcelona's 1-1 LaLiga draw with Deportivo Alaves on Saturday after feeling dizzy and suffering apparent discomfort in his chest.

The City great was sent to hospital for a cardiac exam and will now not be available for Barca until at least February, with treatment in that time set to determine the extent of his recovery process.

The news came as a shock for Barca given Aguero had started just two games for the club since joining from City, and the Argentinian has been in Guardiola's thoughts.

"I sent a message to him through his agent," Guardiola told a news conference on Tuesday. "It's difficult news for him and his family.

"We wish him – everyone at Manchester City from the staff to the chairman, all the people – a safe recovery, doesn't matter the time.

"Health is more important than anything else. I'm sure he's in very good hands, with the best doctors.

"He will take care of himself. I wish him the best recovery as possible and he can come back to play again, otherwise he [can] enjoy his life and enjoy what he has done.

"I don't know what he has, but now he knows it [that there is something wrong], he has to be careful and safe for the rest of his life."

Kyle Walker joined Guardiola for media duties ahead of a Champions League game against Club Brugge and was also rocked by the situation affecting Aguero, a team-mate of his for four years.

Walker also played at Tottenham alongside Christian Eriksen, who is yet to return to the pitch since suffering a cardiac arrest during Denmark's first Euro 2020 match, and such scares seemed to put life into perspective for the England international.

"It's a shock when it happens to anyone," Walker said. "I played with Christian [Eriksen]. You think about them and the family. I'm glad they're okay.

"We're all fit athletes and train hard every day. You have to take precautions and his health is more important than football at the minute.

"We're all human in more ways than one. We make mistakes, we put in good performances. Health is key, without health you're nothing.

"As long as Sergio's okay… I know Christian is because I spoke to him a couple of weeks ago. I spoke to him on text, said I hope he's okay.

"I played in the game at Spurs when [Fabrice] Muamba went down. Seeing it happen with a few people which isn't nice.

"The main priority is health, [Aguero] should take as much time, being fit and healthy is the main priority."

Tottenham have appointed Antonio Conte as their new head coach after acting quickly to replace Nuno Espirito Santo.

Former Chelsea, Juventus, Inter and Italy boss Conte agreed a contract running until summer 2023 to take charge of the London club, Spurs announced on Tuesday.

With Conte having also been linked to Manchester United, Spurs moved quickly to seal his signature after sacking Nuno.

Conte said: "I am extremely happy to return to coaching, and to do so at a Premier League club that has the ambition to be a protagonist again.

"Tottenham Hotspur has state-of-the-art facilities and one of the best stadiums in the world.

"I can't wait to start working to convey to the team and the fans the passion, mentality and determination that have always distinguished me, as a player and as a coach."

Tottenham made an unsuccessful attempt to recruit 52-year-old Conte prior to their appointment of Nuno in the close season.

That was part of what became a chaotic process to replace Jose Mourinho on a permanent basis, with Nuno seemingly well down the list of candidates after Ryan Mason had taken interim charge towards the end of the 2020-21 season.

Conte left Inter at the end of last season after his two years in charge climaxed with him winning the club's first Serie A crown for 11 years, ending the dominance of his former club Juventus, with whom he claimed the Scudetto on three occasions as a coach.

He won the Premier League and FA Cup during two years in charge of Chelsea from 2016 to 2018, leaving after his second season ended with a fifth-place finish in the Premier League.

Conte thanked Tottenham chairman Daniel Levy for showing persistence.

New boss Conte said on Spurs' official website: "Last summer our union did not happen because the end of my relationship with Inter was still too recent and emotionally too involved with the end of the season, so I felt that it wasn't yet the right time to return to coaching.

"But the contagious enthusiasm and determination of Daniel Levy in wanting to entrust me with this task had already hit the mark. Now that the opportunity has returned, I have chosen to take it with great conviction."

Nuno's reign at Spurs ended just 10 league matches and four months into a two-year contract he signed in June. He had previously spent four largely successful years in charge of Wolves.

A 3-0 home defeat to Manchester United on Saturday, when home fans expressed their frustration, proved to be his final game at the helm, with his top-flight total representing the lowest number of Premier League matches in charge for any permanent Tottenham manager in history.

The club are desperate to end a run that has not seen them win a trophy since 2008, after huge investment in an impressive new stadium.

Spurs have been runners-up in the Premier League and Champions League during that 13-year span, as well as losing three times in the EFL Cup final.

Conte's tenure will begin when Tottenham play at home to Vitesse in the Europa Conference League on Thursday before they face Everton in the Premier League at Goodison Park on Sunday.

Tottenham's managing director of football Fabio Paratici welcomed the appointment, saying: "We are delighted to welcome Antonio to the club. His track record speaks for itself, with vast experience and trophies in both Italy and England.

"I know first-hand the qualities Antonio can bring to us, having worked with him at Juventus, and look forward to seeing his work with our talented group of players."
