The NBA has postponed the Boston Celtics-Miami Heat showdown due to health and safety protocols amid the coronavirus pandemic.

Sunday's contest was set to go ahead, despite the Celtics missing seven players – including star pair Jayson Tatum and Jaylen Brown – because of COVID-19 protocols, and nine in total.

But the NBA announced the postponement just hours before tip-off after a Heat player reportedly returned an inconclusive coronavirus test, leaving Miami without the required eight players to play due to contact tracing.

Heat guard Avery Bradley (health and safety protocols) had been ruled out of the game earlier in the day.

The Celtics were set to have the minimum eight players available against the Heat after Javonte Green, Semi Ojeleye, Grant Williams, Robert Williams II and Tristan Thompson were listed as outs pre-game.

Injuries had already forced Celtics pair Kemba Walker (knee) and Romeo Langford (wrist) to miss the scheduled meeting.

It comes as COVID-19 outbreaks impact the NBA following a coronavirus-hit 2019-20 campaign in the United States.

Eastern Conference leaders the Philadelphia 76ers were depleted for Saturday's loss to the Denver Nuggets after Seth Curry tested positive for coronavirus.

Contract tracing seriously impacted Doc Rivers' 76ers, who were without Curry, Tobias Harris, Matisse Thybulle and Vincent Poirier, paired with injures to All-Star duo Joel Embiid and Ben Simmons.

Philadelphia were only able to dress eight players against the Nuggets, though Mike Scott was unable to play due to a knee injury.

The Celtics own a 7-3 record in the Eastern Conference, ahead of last season's NBA Finals runners-up the Heat (4-4).

LaMelo Ball created history in the Charlotte Hornets’ 113-105 win against the Atlanta Hawks by becoming the youngster player of all time to score a triple-double.

The first round rookie announced his arrival in the NBA after coming off the bench to post 22 points, 12 rebounds and 11 assists in a dazzling 31 minutes on court.

Terry Rozier added 23 points and PJ Washington posted 22 points to help Charlotte improve to 5-5 as the Hawks rallied with De'Andre Hunter scoring 20 points but fall to to 4-5.

Mikal Bridges starred and six players hit double figures as the Phoenix Suns advanced to 7-3 in the Western Conference with a 125-117 win over the Indiana Pacers.

Bridges led the scoring with a career-high 34 points as the Pacers fell to 6-3 in the Eastern Conference despite Domantas Sabonis' 28 points and 22 rebounds.

Earlier in the day, a threadbare Philadelphia 76ers fell to 7-3 after losing 115-113 to the Denver Nuggets as coach Doc Rivers had only seven players available due injury and COVID-19 protocols.

The Boston Celtics edged the Miami Heat in the NBA on Wednesday, while the Milwaukee Bucks claimed their third straight win.

In a rematch of last season's Eastern Conference finals, the Celtics overcame the Heat 107-105 in Miami.

Jayson Tatum (27 points) and Jaylen Brown (21 points and 12 rebounds) led the Celtics (6-3) to their win.

But Payton Pritchard (six points) made the decisive lay-up with 0.2 seconds remaining to secure the win.

The teams kneeled in protest ahead of the clash, in response to a riot on Capitol Hill and after no charges were brought against the police officer who shot and seriously injured Jacob Blake, a black man, in Kenosha in August last year.

Meanwhile, the Bucks made it three straight wins by easing past the Detroit Pistons 130-115.

Giannis Antetokounmpo guided Milwaukee into a 5-3 record with 25 points, eight rebounds and four assists.

Hayward heroic, Beal brilliance not enough for Wizards

Gordon Hayward scored a career-high 44 points to see the Charlotte Hornets past the Atlanta Hawks 102-94.

Bradley Beal equalled a Washington Wizards record, but it was not enough. Beal tied the franchise record with 60 points in a 141-136 loss to the Philadelphia 76ers.

Joel Embiid once again inspired the 76ers, scoring 38 points to go with eight rebounds and five assists as they improved to 7-1.

A 35-point haul from Malcolm Brogdon helped the Indiana Pacers beat the Houston Rockets 114-107.

Curry cools off

After 92 points in the previous two games, Stephen Curry cooled off. He went five-of-17 from the field for 13 points in 35 minutes as the Golden State Warriors fell to the Los Angeles Clippers 108-101.

Beal ties record

Beal was in spectacular form for the Wizards. He equalled Gilbert Arenas' record of 60 points for the Wizards against the Los Angeles Lakers in 2006.

Wednesday's results

Indiana Pacers 114-107 Houston Rockets
Orlando Magic 105-94 Cleveland Cavaliers
Philadelphia 76ers 141-136 Washington Wizards
Charlotte Hornets 102-94 Atlanta Hawks
Boston Celtics 107-105 Miami Heat

76ers at Nets

The 76ers will look to continue their good start to the season when they take on the Brooklyn Nets (4-4). The Nets will again be without star Kevin Durant, who is in quarantine.

The Boston Celtics and Miami Heat played "with a heavy heart" after highlighting the different treatment of protesters in the United States.

Players kneeled ahead of the clash at AmericanAirlines Arena before the game went ahead.

It came in response to riot on Capitol Hill and after no charges were brought against the police officer who shot and seriously injured Jacob Blake, a black man, in Kenosha in August last year.

A statement from Heat and Celtics players read: "2021 is a new year, but some things have not changed.

"We play tonight's game with a heavy heart after yesterday's decision in Kenosha, and knowing that protesters in our nation's capital are treated differently by political leaders depending on what side of certain issues they are on.

"The drastic difference between the way protesters this past spring and summer were treated and the encouragement given to today's protesters who acted illegally just shows how much more work we have to do.

"We have decided to play tonight's game to try to bring joy into people's lives. But we must not forget the injustices in our society, and we will continue to use our voices and our platform to highlight these issues and do everything we can to work for a more equal and just America."

Supporters of United States president Donald Trump stormed Capitol Hill as Joe Biden's election victory was due to be certified.

At least 13 people were arrested, police said.

Seven players hit double figures as the Philadelphia 76ers surged to 6-1 while Malcolm Brogdon landed an overtime winner as the Indiana Pacers take up chase in the East.

Eastern Conference leaders Philadelphia remain ahead of the pack after a second-quarter flurry helped to sink the Charlotte Hornets, 118-101, with Tobias Harris leading the scoring on 22 points.

Joel Embiid (14 points and 11 rebounds) and Ben Simmons (12 points and 10 rebounds) played key supporting roles with double-doubles as the 76ers continue to fly high.

Indiana improved to 5-2 in a 118-116 thriller against the New Orleans Pelicans after Brogdon capped his double-double with the clutch OT winner, while Victor Oladipo top scored for the Pacers with 25 points.

In-form Pelicans duo Brandon Ingram and Zion Williamson combined for 55 points in the loss, as Ingram scored 31 and Williamson recorded a double-double with 24 points and 10 rebounds.

Orlando also stayed in the hunt for top spot as Aaron Gordon (24 points, 11 rebounds) and Nikola Vucevic (23 points) inspired the Magic to move to 5-3 with a 103-83 victory over the Cleveland Cavaliers.

Malcolm Brogdon hits the game-winning floater in OT as the @Pacers pick up their 5th W of the season!

Doncic, Giannis go off as Mavs and Bucks win

Luka Doncic dominated with 33 points and a triple-double as the Dallas Mavericks ended the Houston Rockets’ winning streak with a 113-100 win.

Doncic added 16 rebounds and 11 assists, while Tim Hardaway Jr shot for 30 points to boost the Mavs. Houston's Christian Wood, Eric Gordon and a returning James Harden all put up more than 20 points.

The NBA is back! A shortened schedule, a new play-in tournament and increased roster sizes have created plenty of interest in a new season.

A December start seems to have caught a few of the potential title hopefuls a little cold, though it is still early days. The key is not about starting fast, but finishing strong.

Still, some have hit the ground running. Each week, Stats Perform will take a look at the players who are impressing, as well as those seemingly stuck in a bit of a slump.

For this opening edition, however, all statistical comparisons are made to performances on average across the entire 2019-20 season.
 

RUNNING HOT... 

Stephen Curry (32.3ppg versus 20.8ppg) 

Scoring 62 points in a game sure helps to boost the average. Curry actually started out a little slowly – hardly a surprise considering injury meant he played just five games in the previous campaign – as he made only 13 of his combined 48 field goal attempts in defeats to the Nets and Bucks. However, Curry was certainly cooking against the Portland Trail Blazers on Sunday, hitting eight three-pointers as he posted a new career-high points total. So far in this season, he is making 4.3 three-pointers per outing. 

Christian Wood (23.8ppg versus 13.1ppg) 

These are uncertain times in Houston, where James Harden seemingly no longer wants to be. While his future remains the headline story for the franchise, Christian Wood has quickly shown why he was such an astute signing. Having gone undrafted out of college, the 25-year-old flashed potential with the Detroit Pistons in 2019-20, tempting the Rockets to sign him to a three-year, $41million deal. Their reward? Wood has averaged 23.8 points while playing 36.5 minutes for a team that boasts a 2-2 record through four games. 

Kyle Anderson (16.7ppg versus 5.8ppg) 

Opportunity knocks for Anderson in Memphis due to the absence of Jaren Jackson Jr with a knee issue. The forward's minutes on court have risen as a result – and so, too, has his production. Having never averaged in double digits for points for his previous six seasons in the NBA, Anderson is now up at 16.7 per game for the Grizzlies. Ja Morant was, less surprisingly, on the rise in terms of his scoring output as well, up at 26.3 points per game before suffering an ankle injury. 

Luguentz Dort (14.6ppg versus 6.8ppg) 

Someone has to score points for Oklahoma, right? GM Sam Presti is clearly in it for the long haul in terms of a rebuild, considering the number of moves made in the offseason and draft picks now owned by the team. Still, Dort remains on the roster and has stepped up to accept greater responsibility. The Canadian has raised his successful three-point attempts from an average of 0.8 to 2.4 a game, shooting an impressive 44.4 per cent from deep. Team-mate Isaiah Roby is another to catch the eye for the Thunder, averaging 13 points and 6.5 total rebounds.

GOING COLD...

Devonte' Graham (9.0ppg versus 18.2ppg)

The moment Charlotte selected fellow point guard LaMelo Ball with the third pick in the draft, Graham was under pressure. He retained his starting job in the Hornets' backcourt but the pressure is mounting now, considering the form of both players. While Ball seems to be a quick learner after some preseason concerns, his teammate has struggled. Graham is at just nine points per game - half his average from the previous season. His three-point shooting has dipped to 2.0 made per outing from 3.5. He forced himself off the bench and into the rotation for the Hornets last year, yet could soon find himself moving in the opposite direction.

Jimmy Butler (8.3ppg versus 19.9ppg)

There are reasons behind the five-time NBA All-Star's sluggish start. Butler has featured in just three games so far - and one of those he only played in the first half, with an ankle issue keeping him off the court for the remainder of the clash with the Pelicans. He averaged 19.9 per game for a Heat team that made it all the way to the Finals last term. The early going has seen an 11.6-point decrease in his scoring output, though expect that to rise as the weeks progress.

Kelly Oubre Jr. (9.7ppg versus 18.7ppg)

Oubre was on the merry-go-round headlined by Chris Paul going from Oklahoma to Phoenix. His form last season with the Suns was not enough for the Thunder to keep him around, though, as they dealt him to Golden State. It has not been plain sailing with the Warriors; while not required to contribute quite so much on offense for his new team, the concern is his three-point shooting. Having made 1.9 on average per game last season, Oubre's been successful with two of his 30 attempts so far. The early report card for him reads as such: Must do better.

The Los Angeles Lakers made it back-to-back wins in the NBA, while the Milwaukee Bucks thrashed the Chicago Bulls on Friday.

LeBron James posted a triple-double of 26 points, 11 rebounds and 10 assists as the Lakers beat the San Antonio Spurs 109-103.

Anthony Davis had a game-high 34 points, to go with 11 rebounds, as the Lakers enjoyed a second win in three days over San Antonio.

Keldon Johnson (26) and DeMar DeRozan (23) combined for 49 points for Spurs.

Giannis Antetokounmpo (29 points, 12 rebounds and eight assists) helped the Bucks crush the Bulls 126-96.

Milwaukee had seven players in double-digits and the Bucks hit 22 three-pointers.

No team has hit more threes through the first six games of a season than the Bucks' 108 to begin 2020-21.

Doncic lifts Mavericks, Leonard's Clippers lose

Luka Doncic finished with 27 points, 15 rebounds and seven assists in the Dallas Mavericks' 93-83 win over the Miami Heat.

Kawhi Leonard fell just short of a triple-double as he posted 20 points, 16 rebounds and nine assists, but the Los Angeles Clippers went down to the Utah Jazz 106-100.

The Portland Trail Blazers eased past the Golden State Warriors 123-98 thanks largely to 34 points from Damian Lillard. Lillard joined Clyde Drexler as the only players to score 15,000 points with the Trail Blazers.

Deandre Ayton's double-double of 22 points and 11 rebounds helped the Phoenix Suns improve to 5-1 with a 106-103 victory against the Denver Nuggets.

Nets slip to 3-3

Kyrie Irving struggled from the field, shooting six-of-21 for 18 points, as the Brooklyn Nets were beaten by the Atlanta Hawks 114-96. Kevin Durant finished with 28 points.

Grant delivers huge dunk

Jerami Grant produced a huge dunk as part of his 24 points in the Detroit Pistons' first win of the season – a 96-93 victory over the Boston Celtics.

Friday's results

Memphis Grizzlies 108-93 Charlotte Hornets
Detroit Pistons 96-93 Boston Celtics
Dallas Mavericks 93-83 Miami Heat
Atlanta Hawks 114-96 Brooklyn Nets
Milwaukee Bucks 126-96 Chicago Bulls
Washington Wizards 130-109 Minnesota Timberwolves
Los Angeles Lakers 109-103 San Antonio Spurs
Phoenix Suns 106-103 Denver Nuggets
