Ben Simmons insisted he was unfazed about talk over his future with the Philadelphia 76ers after James Harden joined the Brooklyn Nets.

Simmons was the subject of trade rumours as the 76ers were linked to Harden, whose move from the Houston Rockets to the Nets was confirmed on Thursday.

But, after the 76ers' 125-108 win over the Miami Heat on Thursday, the 24-year-old said it was just part of the game.

"This is a business, things like that happen," Simmons told a news conference.

"The only thing I can control is how I approach my workouts, the games and my day-to-day things.

"I'm just trying to be professional and do the right thing and help my team get wins."

Asked if he was happy to be in Philadelphia, Simmons responded: "Of course."

Simmons posted a triple-double of 10 points, 12 assists and 10 rebounds in the win over the Heat.

It was his 30th triple-double in the NBA. Only Oscar Robertson (75 games) and Magic Johnson (190) have managed that quicker than Simmons (228).

Philadelphia head coach Doc Rivers was delighted with Simmons' performance as the 76ers improved to 9-4.

"I thought tonight is who he has to be every night. I loved the way he played. I loved how he played under control, didn't force it, took gaps when they were there," he said.

"He was a presence on the floor for us and not just on the offensive end but on the defensive end as well and that takes us to a different level when he plays like that."

Brooklyn Nets general manager Sean Marks is confident Kevin Durant, Kyrie Irving and James Harden will gel as they work towards a "common goal".

The Nets confirmed on Thursday they had completed a blockbuster trade to land eight-time All-Star Harden from the Houston Rockets.

Questions have been asked over whether Durant, Harden and Irving can work together, but Marks is confident.

"These guys have given us the right answers. They've said hey, they want to play together, they can see this fitting," he told a news conference.

"They're at a time in their careers – I don't want to speak for each one of them because I let them have their own their own voice and their narrative around this – but I think they understand that there's without a doubt going to be some nights where one or two need to sacrifice for the other and so forth. But I think they're all looking for a common goal.

"We’re all looking for that common goal, as I've said before, is to be the last team standing. I think when you have a group that is willing to sacrifice, and play hard, play together on the court, and they already have a relationship, a prior relationship to this, so I think that will help."

Harden, Durant and Irving all rank in the top 10 in the NBA in scoring average since the latter's rookie season in 2011-12 (minimum 500 games).

Durant or Harden have won seven of the past 11 NBA scoring titles. No Brooklyn qualifier has ever finished higher than fifth in the league.

Marks said the opportunity to land a player like Harden came at a good time for the Nets.

"The timing was right for us. And fortunately, any time you get an opportunity to acquire or try to acquire a player of this calibre it's something you do look hard at [and] is something we did," he said.

"The process sped up very, very rapidly and very quickly over the last 48 hours."

Madison Keys is set to miss the Australian Open after testing positive for coronavirus.

The 2017 US Open runner-up announced on Thursday that she contracted COVID-19 before she was due to fly out for the first grand slam of the year.

Keys did not state she will definitely miss the major, which starts on February 8, but it appears the American will not make the trip to Melbourne.

The American wrote on Instagram: "Hi everyone, I wanted to let you know that I unfortunately tested positive for COVID-19 before I was supposed to fly to Australia.

"I'm very disappointed to not be able to play in the coming weeks after training hard in the off-season and knowing Tennis Australia and the tours did so much to make these events happen.

"I am self-isolating at home and will continue to follow all the necessary health precautions. I look forward to being back on tour next month."

It was revealed earlier in the day that three-time major winner Andy Murray has also tested positive for the virus, but still hopes to play in the Australian Open.

Meanwhile, world number 50 Tennys Sandgren was cleared to board a flight from the United States bound for Melbourne despite revealing he returned a new positive coronavirus test this week. 

The American, twice a quarter-finalist at Melbourne Park, initially posted to social media on Wednesday that he had tested positive for the virus for a second time. 

Although his first instance of having the illness was recorded in November, the 29-year-old's participation in the tournament appeared to be in doubt. 

But as he continued to update followers through the day, it emerged he had been allowed to board his flight. 

Players will only be allowed into Australia with proof of a negative test just prior to departure, or with approval to travel as a recovered case at the complete discretion of an Australian government authority.

Anyone wanting to travel out for the tournament who previously tested positive is required to provide additional and highly detailed medical information as proof they are a recovered case and no longer infectious or a risk to the community.

James Harden has been thanked by the Houston Rockets after being traded to the Brooklyn Nets.

Three-time NBA scoring champion Harden has linked up with former Oklahoma City Thunder team-mate Kevin Durant and Kyrie Irving in Brooklyn, who have gone all in on a championship run by bringing in the 2018 MVP.

The Nets gave up Jarrett Allen, Taurean Prince, Caris LeVert, Radions Kurucs, three first-round draft picks (2022, 2024 and 2026) and four first-round pick swaps (2021, 2023, 2025 and 2027) to acquire Harden.

Allen and Prince were sent to the Cleveland Cavaliers, who provided Houston with Dante Exum and a 2022 first-round pick via the Milwaukee Bucks. Brooklyn received a 2024 second-round pick from the Cavs to complete the deal.

The Rockets are expected to send LeVert and a 2023 second-round pick to the Indiana Pacers in exchange for two-time All-Star Victor Oladipo.

Harden requested a trade prior to the start of the season and following a 117-100 loss to the Los Angeles Lakers on Tuesday he said: "It's something that I don't think can be fixed."

The Rockets granted their franchise player his wish on Thursday and owner Tilman Fertitta praised him for his achievements in Houston.

"On behalf of the entire Rockets organisation and the City of Houston, I'd like to thank James Harden for an amazing eight-plus seasons in a Rockets uniform," said Fertitta in a statement.

"James has provided us with so many great memories as we've watched him grow from Sixth Man of the Year to a perennial All-Star and MVP.

"My family and I also want to thank James for his many off the court contributions, including generous charitable donations and multiple annual community events.

"We wish James the best of luck and will always be grateful for the memories."

Harden is second on the Rockets' all-time scoring list with 18,365 points, only trailing Hakeem Olajuwon (26,511) – a two-time NBA champion in Houston.

He averaged 29.6 points, 6.0 rebounds and 7.7 assists during his time with the Rockets.

Harden led them to the Western Conference Finals in 2014-15 and 2017-18, losing to the Golden State Warriors on both occasions.

LaMelo Ball's NBA career with the Charlotte Hornets got off to a subpar start. 

In fact that might just be a generous description of his NBA debut. It was downright brutal. 

The third overall pick of this year's draft played a scoreless 15 minutes in his first game, missing all five of his field-goal attempts in Charlotte’s 121-114 loss to the Cleveland Cavaliers on December 23. 

Not only did he fail to score, the highly-touted playmaker also turned the ball over three times, becoming only the second player in the last 35 years to finish without a point while taking at least five shots with three or more turnovers in 15-plus minutes in their NBA debut, joining the Golden State Warriors' Brandon Williams in 1998. 

While he got off to a shaky start, things have since gone much better. 

Better actually might not be kind enough in describing his recent play. He's been outstanding. 

On the onset of the 2020 draft, the 6-foot-7 point guard was widely considered to have the highest ceiling of all the prospects. An adept ball-handler, scouts marvelled at his passing, court vision and his ability to push the ball up the court. 

Though Ball possesses an immense skillset and has a comprehensive understanding of the game, making the jump from Australia's National Basketball League to the NBA would admittedly take time. 

It took him all of one week. 

With 22 points, eight rebounds and five assists in a win over the Dallas Mavericks on December 30, he became the first player in the last 35 years to reach those numbers in just his fourth game, and he's continued to stuff the stat sheet with impressive numbers. 

Since then, he's had two more games with 15 or more points, eight or more rebounds and five or more assists. Only four other players have had more such games in that span – the Denver Nuggets' Nikola Jokic (six), Mavericks' Luka Doncic (five), New York Knicks' Julius Randle (five) and Los Angeles Lakers' LeBron James (four). 

Over the course of three games from January 8-11, he racked up 42 points, 36 rebounds and 27 assists, joining Ben Simmons in 2017 and Lamar Odom in 2000 as the only rookies in the last 35 years with at least 40 points, 35 boards and 25 assists over a three-game span. 

In the middle game of that three-match stretch, Ball made history. At 19 years and 140 days, he became the youngest player ever to record a triple-double by notching 22 points, 12 rebounds and 11 assists in Saturday's win over the Atlanta Hawks. 

Despite stumbling out of the gate with his forgettable debut, he still reached the 10-game mark with 131 points, 63 rebounds and 59 assists. In the last 35 seasons, only two other rookies have reached those numbers after 10 games – James in 2003 and Simmons in 2017. 

Ball's passing has been as advertised. He's finding his open team-mates and setting them up for success. 

Among the 100 players with at least 30 assists, he has the league's 10-best assist rate – the estimation of percentage of field goals made by team-mates while he's on the floor. At 36.8 per cent, Ball sits just a bit back of James, whose eighth at 37.6. 

With 71 assists on the season, Ball has eight fewer assists than Devonte' Graham for the most on the Hornets. He does, however, lead Charlotte with 84 rebounds, and if he does surpass Graham and finish the season leading the team in both rebounds and assists, he'll join Michael Jordan in 1984-85 and Blake Griffin in 2010-11, as the only rookies in the last 40 years to lead their team in both categories. 

Not only is Ball flourishing in the part of his game many thought he would eventually excel in, he is also finding success in areas that were believed to be some of his biggest weaknesses – shooting and defense. 

After shooting a dreadful 24 per cent from 3-point range in Australia's NBL, Ball is making a respectable 33.9 per cent of his 3s. Nothing outstanding, but the league average on 3s is 36.6 per cent. 

He’s also showing a proficiency at knocking down shots just inside the arc. His 50 per cent shooting on mid-range jumpers is tied with seven others for 17th in the NBA among those with at least 100 field-goal attempts. 

Defense was another area that many expected would take Ball time to grasp and be competent in, but he’s already proven to be up to speed, leading all rookies with 22 defensive stops. 

Not only does he lead all first-year players in defensive stops, he also leads all rookies in points (143), rebounds (84), assists (71), as well as steals (18). 

If Ball continues to thrive on the court and finishes the season leading all rookies in points, rebounds and assists, he’ll become just the seventh player in NBA history to accomplish that feat, joining Elgin Baylor (1958-59), Wilt Chamberlain (1959-60), Oscar Robertson (1960-61), Walt Bellamy (1961-62), Alvin Adams (1975-76) and Michael Carter-Williams (2013-14). 

Not surprising, but each of the previous six won the Rookie of the Year Award. 

Playing at a level few rookies have before him, Ball is the early frontrunner to win this season's award. 

Good thing for him the trophy isn't handed out after one game. 

Ferrari driver Charles Leclerc has tested positive for coronavirus, the team have confirmed.

The 23-year-old was already isolating having been in close contact with someone who had contracted COVID-19.

Ferrari said Leclerc is isolating at home in Monaco and is displaying mild symptoms.

A team statement read: "Scuderia Ferrari Mission Winnow driver Charles Leclerc has tested positive for COVID-19.

"In accordance with the team's protocols, Charles is tested regularly and yesterday, the result from his latest test came back positive. 

"Charles notified us immediately and has informed everyone he has been in close contact with in the last few days.

"He is currently feeling ok with mild symptoms and is now self-isolating at home in Monaco."

Leclerc added on his Instagram stories: "Hello guys. I hope you are all staying safe.

"I want to let you know that I have tested positive for COVID-19. I am regularly checked according to my team's protocols.

"Unfortunately, I learned that I have been in contact with a positive case and immediately went into self-isolation, notifying anyone I had contact with. A subsequent test I took has come back positive.

"I am feeling okay and have mild symptoms. I will remain in isolation in my home in Monaco in compliance with the regulations set by the local health authorities.

"Stay safe and take care."

World champion Lewis Hamilton tested positive towards the end of the 2020 F1 season, while Lance Stroll and Sergio Perez have also previously missed time due to coronavirus.

James Harden has completed a blockbuster trade from the Houston Rockets to the Brooklyn Nets, it has been confirmed.

Widespread reports on Wednesday revealed Harden's eight-and-a-half-year stay in Houston was set to end, with the Nets agreeing a monster deal.

The Philadelphia 76ers had also been mooted as potential suitors, but Brooklyn's offer saw the Rockets receive Caris LeVert, Rodions Kurucs, three first-round draft picks (2022, 2024 and 2026) and four first-round pick swaps (2021, 2023, 2025 and 2027).

In a three-way move, Jarrett Allen and Taurean Prince were sent to the Cleveland, who put in Dante Exum and a further first-round draft pick (2022 via Milwaukee) for Houston as well as a second-round draft pick (2024) for the Nets.

The Rockets are expected to swiftly move LeVert and a second-round pick on to the Indiana Pacers for Victor Oladipo, although that switch was not initially confirmed alongside the Harden deal on Thursday.

Harden had been keen on a move prior to the start of the 2020-21 season and has now got his wish, linking up with Kevin Durant - his former Oklahoma City Thunder team-mate - and Kyrie Irving.

Brooklyn general manager Sean Marks said: "Adding an All-NBA player such as James to our roster better positions our team to compete against the league's best.

"James is one of the most prolific scorers and playmakers in our game, and we are thrilled to bring his special talents to Brooklyn.

"While we are excited to welcome James and his family to the Nets, we also want to thank the players who are departing.

"Caris, Jarrett, Rodions and Taurean were instrumental to the team's success and have made an enormous impact on our organisation.

"It has been a pleasure watching them grow both as players and as people and they will always be part of our Nets family. We wish each of them and their families all the best in the future."

Although trade talks were said to be ongoing for some time, speculation ramped up in the hours after Houston's defeat to the Los Angeles Lakers on Tuesday.

An out-of-sorts Harden put up just 16 points in 31 minutes in the 117-100 defeat and later stormed out of a post-game news conference after saying: "I literally have done everything that I can."

Those comments prompted a backlash from team-mates John Wall and DeMarcus Cousins, who both signed in the offseason as Houston once again rebuilt.

The Rockets failed to win a championship during Harden's time despite reaching the Western Conference Finals in both 2014-15 and 2017-18, with their star guard the league's MVP in the latter season.

Harden averaged 29.6 points per game in the regular season during his time with Houston, although that dropped slightly to 28.4 in the playoffs.

His return of 24.8 points through eight games this year was his worst average over a season for the Rockets.

The Australian Open has hinted Andy Murray will not be able to compete in Melbourne following his positive test for coronavirus.

Murray, a five-time finalist at the Australian Open, remains in good health and is isolating at home.

The three-time grand slam winner is still hoping to play and travel to Australia later than planned.

However, a statement from the tournament cast serious doubt on his involvement, with Murray – ranked 123rd in the world – having initially been granted a wildcard to play.

The statement read: "Andy Murray has advised that he has tested positive for COVID-19 and is isolating at home in the UK.

"Unfortunately, this means that he will be unable to join the official AO charter flights arriving in Australia in the coming days to go through the quarantine period with the other players.

"The AO fans love Andy, and we know how much he loves competing here in Melbourne and how hard he'd worked for this opportunity."

The first grand slam of the year is starting three weeks later than it normally would on February 8 due to the complications of players flying into Australia amid the ongoing coronavirus pandemic.

Tournament organisers are putting on 15 chartered flights, which will operate at 25 per cent capacity, to bring players to the tournament.

Before boarding, competitors must test negative and will undergo a series of tests once in the country, while undergoing a 14-day quarantine period in Melbourne.

It was after a first-round defeat at the Australian Open two years ago that Murray stated his career might be over due to an ongoing hip injury.

James Harden has completed a blockbuster trade from the Houston Rockets to the Brooklyn Nets, it has been confirmed.

Andy Murray's participation at the Australian Open is in doubt following a positive COVID-19 test.

Three-time grand slam champion Murray remains in good health but is isolating at home.

The 33-year-old Briton is still hopeful of being able to travel to Australia later than planned and taking part in the first grand slam of the year.

Murray received a wildcard for the Australian Open, where he has been a runner-up on five occasions.

It is set to be the Briton's first participation at Melbourne Park since announcing after a first-round loss in 2019 that his career was in the balance due to a persistent hip injury.

The Australian Open is scheduled to get under way on February 8.

Rafael Nadal will be without his coach Carlos Moya due to the pandemic, while Dominic Thiem's coach Nicolas Massu tested positive before travelling to Australia.

It is still hoped that Massu can make the trip following a negative result.

Wayne Bennett will not continue as coach of Queensland for the 2021 State of Origin series so he can focus on his job at South Sydney Rabbitohs. 

Bennett returned to lead the Maroons in October of last year, taking on the role after Kevin Walters had stepped down following his appointment at Brisbane Broncos. 

Queensland went on to win 2-1 - beating New South Wales 20-14 in the deciding game in Brisbane - but the search is now on for a new coach ahead of this year's series.

"We were really grateful that Wayne made himself available to help us out last year," Queensland Rugby League managing director Robert Moore said in a statement. 

"We understand the decision Wayne has made in his last year of his contract with the South Sydney Rabbitohs, as he's eager to concentrate his efforts on them because they've been so close [to a premiership]," Moore said. 

"With Wayne's decision, we've now moved to a process to consider the next appointment and we anticipate that process will be completed early this year." 

The Origin games are scheduled to take place in June and July, having been shifted to after the NRL season last year due to the impact of the coronavirus pandemic.

Dallas Mavericks duo Luka Doncic and Rick Carlisle were delighted to see Kristaps Porzingis back in action after the Latvian made his first appearance of the NBA season on Wednesday. 

Having undergone knee surgery in October, Porzingis had missed Dallas' first nine games as he continued his recovery.

A potential return on Monday was then scuppered when the clash with the New Orleans Pelicans was postponed in accordance with the league's health and safety protocols amid the ongoing coronavirus pandemic. 

However, the former first-round pick by the New York Knicks was finally able to take the court again against the Charlotte Hornets, contributing 16 points during his 21 minutes in a 104-93 triumph. 

"He' an amazing player," Doncic - who led the way with 34 points - said, according to Dallas' official website. 

"He's got to get back into rhythm, and I think for the first game he played amazing. He's going to keep improving and we're going to need him a lot."

Mavs coach Carlisle admitted Porzingis' return – admittedly on a restriction in terms of minutes – makes a huge difference to the team, including helping to alleviate some of the pressure on the shoulders of Doncic. 

"When both of those guys are out there, it's a game-changer for us because you've got two guys that can both play on the inside and really space the floor on the outside," Carlisle said.  

"They can both put the ball on the floor and make plays. 

"You get two franchise players, it's important to have them on the floor together and available to play. You look at every team in this league, if they're without one of their cornerstone guys it's going to be a lot tougher job. 

"I think everybody feels a lot better now that KP is back in the mix."

The game was also notable for Carlisle in terms of a personal milestone, as he reached 800 victories in his coaching career.

Porzingis himself accepted he had been a little too eager to make an impact during his comeback, knowing his involvement in the game was always going to be limited. 

"What I think didn’t help me was knowing that I had the minutes restrictions," Porzingis said. "I was trying to do as much as I could in those minutes that I had. 

"Sometimes you don't make the best decisions when you really want to be aggressive, but it's okay. I wanted to be aggressive for the time I was going to be out there, and most importantly [it was the] first game and first win for me."

Tennys Sandgren was cleared to board a flight from the United States bound for Melbourne ahead of the Australian Open despite revealing he returned a new positive coronavirus test this week. 

The American, twice a quarter-finalist at Melbourne Park, initially posted to social media on Wednesday that he had tested positive for the virus for a second time. 

Although his first instance of having the illness was recorded in November, the 29-year-old's participation in the tournament appeared to be in doubt. 

But, as he continued to update followers through the day, it emerged he had been allowed to board his flight. 

Writing on Twitter, he said: "Wait hold on I think they are trying to get me on 15 min [sic] after the plane was supposed to depart.. my bags still aren't checked lol." 

A follow-up read: "Wow I'm on the plane. Maybe I just held my breath too long. Craig Tiley [Tennis Australia] is a wizard." 

Some expressed concerns about the possibility of Sandgren potentially spreading the virus to fellow passengers and then locals once he arrives in Australia. 

But a statement from the Australian Open has looked to reassure people that players' infectiousness is checked prior to boarding flights. 

It read: "In the case of Tennys Sandgren, who has self-disclosed that he previously tested positive in late November, his medical file had to be reviewed by Victorian health authorities. Upon completion of that review he was cleared to fly.

"Any recovered case must go through this process in order to have an opportunity to travel here for the Australian Open. No one can travel without either proof of a negative test or this special clearance from authorities confirming they are not infectious. 

"Upon arrival all players are immediately placed in a secure quarantine environment for 14 days under the authority of COVID Quarantine Victoria, and will undergo a more rigorous testing schedule than most returning travellers." 

An earlier statement issued by the tournament organisers in reply to Sandgren's tweets said: "Some people who have recovered from COVID-19 and who are non-infectious can continue to shed the virus for several months. 

"Victorian Government public health experts assess each case based on additional detailed medical records to ensure they are not infectious before checking in to the charter flights. 

"Players and their teams are tested every day from their arrival in Australia, a much stricter process than for anyone else in hotel quarantine." 

The first grand slam of the year is due to begin on February 8 after being delayed due to the pandemic. 

Initially it was to run from January 18-31 but was pushed back to help give qualifiers time to travel and complete a two-week quarantine in Australia prior to warm-up events getting under way at the end of the month. 

Players at Melbourne Park will have to follow strict guidelines and protocols, including a five-hour limit on training with a maximum of one team member. 

The teams must stay in their hotel for the other 19 hours of every day, and players have to return six negative COVID-19 tests before being allowed to play.
