LeBron James led the way as the Los Angeles Lakers returned to .500 with a hard-fought 108-103 win over the Minnesota Timberwolves on Sunday.

The four-time NBA MVP had 26 points, seven rebounds, five assists and three steals for the Lakers, who have won three of their past four games.

The Lakers had endured a rough period, losing six out of seven games, but are beginning to re-discover some form.

Russell Westbrook contributed 20 points with three rebounds and five assists but had nine turnovers, while Malik Monk added 22 points.

James also shot nine of 12 from the stripe, moving up to fourth on the all-time NBA free throws made list with 7,695, going past Oscar Robertson. Karl Malone, Moses Malone and Kobe Bryant are the players ahead of the 37-year-old.

Giddey breaks LaMelo's mark for youngest NBA triple-double

Oklahoma City Thunder's 19-year-old rookie Josh Giddey returned from COVID-19 protocols with a bang, becoming the youngest player in NBA history to record a triple-double, breaking LaMelo Ball's mark. Giddey had 17 points, 13 rebounds and 14 assists but OKC were beaten 95-86 by the Dallas Mavericks, who had Luka Doncic return from protocols with a near-triple-double with 14 points, nine rebounds and 10 assists.

Jaylen Brown scored a career-high 50 points, including 21 in the fourth quarter, in the Boston Celtics' 116-111 over-time win over the Orlando Magic. Brown also had 11 rebounds, four assists and two blocks.

Devin Booker scored 24 points with seven rebounds and three assists as the Phoenix Suns improved to 28-8 after beating the Charlotte Hornets 133-99.

Wayward Heat burnt by Kings

Jimmy Butler shot nine of 22 from the field and only one of six from beyond the arc the Miami Heat were beaten by the Sacramento Kings 115-113. Tyler Herro was also eight of 23 from the field.

DeMar DeRozan knocked down a buzzer-beating three-pointer as Eastern Conference leaders the Chicago Bulls dramatically defeated the Indiana Pacers 108-106.

The Bulls ended 2021 on a high with a sixth straight victory that came about when DeRozan picked up the ball with around nine seconds remaining, looked around for options on the court before taking on the shot himself when he noticed the clock winding down.

It was the second time in DeRozan's career he had hit a buzzer-beater, while no Bulls player had achieved the feat since Jimmy Butler in 2016.

DeRozan drained 28 points in total to go with six assists and three rebounds, while Coby White had 24 points. DeRozan is the league leader for both total points and points per game in the fourth quarter.

Victory sees the Bulls head into the new year top of the East, with an identical record (23-10) to the Brooklyn Nets.

Celtics stop the skid to down Suns

The Phoenix Suns entered their showdown with the Boston Celtics with the best record in the NBA but lost for the third time in four games with a 123-108 defeat.

Jaylen Brown and Marcus Smart each scored 24 points with the former registering 11 rebounds and the latter eight assists as the Celtics stopped a three-game losing streak. Robin Williams had a triple-double of 10 points, 11 assists and 11 rebounds.

Deandre Ayton and Jae Crowder missed a third straight game for the Suns due to being placed on the health and safety protocols. Devin Booker put up 22 points, Cam Johnson had 20, Jalen Smith registered 19, and Chris Paul had 14 points and eight assists, but it was all in vain for the Suns.

LeBron James had a season-high 43 points and extended his streak of 30-point games to seven as the Los Angeles Lakers routed the Portland Trail Blazers 139-106 to improve to 18-19 on the season.

Bulls on a hot-streak

Chicago's six-game winning streak has propelled the Bulls to the top of the East and represents their best winning run since December 2017.

Ja Morant's 41 points overshadowed LeBron James as the Memphis Grizzlies won 104-99 to inflict a sixth defeat in seven games for the Los Angeles Lakers on Wednesday.

Morant was excellent for the Grizzlies, draining six of seven three-pointers in his 41-point haul along with 10 rebounds and two assists.

James, who turns 38 on Friday, tried his best for the slumping Lakers with 37 points, 13 rebounds and seven assists, while Russell Westbrook had another triple-double with 16 points, 10 rebounds and 12 assists.

But the four-time MVP came up short in the final 30 seconds, missing a three-point attempt to tie the game before an aimless pass turned the ball over.

Morant skilfully tipped in two to make it 102-97 with 1:15 to go and scored 25 of his 41 points in the second half.

Booker stars as Suns silence Thunder

Devin Booker landed six triples in his 38-point haul as the Phoenix Suns defeated the Oklahoma City Thunder 115-97 to improve to a 27-7, putting them joint-top with the Golden State Warriors. Along with his 38 points, Booker also had seven rebounds and five assists.

The Chicago Bulls had a full team performance in their 131-117 victory over the Atlanta Hawks, with contributions from Zach LaVine (25 points), Coby White (17 points, 12 assists), Nikola Vucevic (16 points, 20 rebounds) and DeMar DeRozan (20 points, eight assists).

Rudy Gobert starred with 22 points and 14 rebounds as the Utah Jazz recorded their eighth straight road win, beating the depleted Portland Trail Blazers 120-105 despite Damian Lillard's 32 points.

Brown struggles from beyond the arc

Jaylen Brown has been in top form lately but hit one of 13 from beyond the arc as the Boston Celtics went down 91-82 to the Los Angeles Clippers.

James Harden scored 39 points in his second game since coming out of the NBA's COVID-19 protocols to inspire the Brooklyn Nets past the Los Angeles Clippers 124-108.

Harden returned with 36 points and a triple-double in the Nets' 122-155 win over the Los Angeles Lakers on Christmas Day and backed that up against the depleted Clippers, who were without star duo Paul George (elbow) and Kawhi Leonard (ACL).

The 2018 NBA MVP was in a dominant mood, with Kevin Durant absent in protocols, shooting 15 of 25 from the field and providing 15 assists, as well as having eight rebounds and two steals.

Patty Mills and Nicolas Claxton both contributed 18 points for the Nets, while the latter had three blocks. Marcus Morris Sr was the Clippers' best with 24 points, five rebounds and six assists.

Bulls duo combine for Hawks defeat

Trae Young returned from COVID protocols with 29 points and nine assists but it was not enough as the Atlanta Hawks lost 130-118 to the Chicago Bulls who had Zach LaVine (30 points, four rebounds, nine assists) and DeMar DeRozan (35 points, five rebounds, 10 assists) impress. LaVine and DeRozan became the first team-mates each with 20 points and five assists in a half over the last 25 seasons.

Ja Morant drained a last-gasp clutch shot to earn the Memphis Grizzlies a thrilling 114-113 win over the Phoenix Suns, who were missing center Deandre Ayton and head coach Monty Williams after entering protocols. Desmond Bane had a career-high 32 points and Morant finished with 33, grabbing the win after Devin Booker (30 points) had put the Suns ahead with five seconds left with a three-pointer.

The Utah Jazz extended their win streak to four games, even without injured Donovan Mitchell, as they defeated the San Antonio Spurs 110-104 with Jordan Clarkson (23 points, eight rebounds, five assists) starring off the bench.

In-form Celtic misses the mark

Jaylen Brown has been in hot point-scoring form lately but his shooting was down at 33.3 percent as the Boston Celtics – without Jayson Tatum who has entered COVID protocols - lost 108-103 to the Minnesota Timberwolves. Brown scored 26 points but made only two of eight from beyond the arc.

Jayson Tatum has entered NBA health and safety protocols and will miss the Boston Celtics' game against the Minnesota Timberwolves on Monday.

Tatum joins eight fellow Celtics players on the list after 13 were sidelined due to COVID-19 protocols recently.

Players must wait 10 days or return two negative COVID-19 tests within 24 hours of each other before they are allowed to return to action.

Tatum contracted COVID-19 in January and was out of action for a short period before returning, when he explained he was suffering long-term effects of having the virus, requiring an inhaler for some time.

The forward leads the Celtics in scoring (25.6) and rebounds (8.6 – level with Robert Williams) per game and is also averaging 3.8 assists and 1.0 steals in a strong season for the 23-year-old.

His absence for the Timberwolves game was announced by the Celtics on their official Twitter page.

The Celtics are ninth in the Eastern Conference with a record of 16-17 and have lost six of their last nine games ahead of their clash with the Timberwolves, who are ninth themselves in the Western Conference.

James Harden marked his return to action with a telling triple-double as the Brooklyn Nets snatched a dramatic 122-115 win over the Los Angeles Lakers.

For the Lakers, LeBron James scored 39 points and became the NBA's highest scorer all-time in Christmas Day games, reaching 422 points on December 25 across his career to surpass Kobe Bryant's 395 haul.

However, Russell Westbrook shot only 4-of-20 from the field, meaning his own triple-double of 13 points, 12 rebounds and 11 assists was tinged with disappointment.

It allowed Harden and Patty Mills to guide the Nets to a hard-earned win over a Lakers side who have lost five successive games to slide to 16-18 for the season.

Mills matched a career-best with 34 points, and his eight three-pointers established a new NBA record for Christmas Day.

Harden's haul of 36 points, 10 rebounds and 10 assists came in his first game out of COVID-19 protocols and boosted the shorthanded Nets to 22-9, with Brooklyn rallying despite being without Kevin Durant, Kyrie Irving and LaMarcus Aldridge, among others.

The Lakers trailed 102-82 entering the final quarter but got back to 115-115 with 45 seconds remaining, yet Nic Claxton restored Brooklyn's lead, and Harden's accuracy from the free-throw line saw them pull clear in the closing moments.

This was the first Christmas Day game with multiple triple-doubles, the NBA said.

Antetokounmpo rebounds with stellar show

Milwaukee Bucks superstar Giannis Antetokounmpo joined Harden in making a stellar return to action, after also serving time in isolation due to the health and safety protocols.

After missing five games, Antetokounmpo scored 36 points and had 12 rebounds in a 117-113 win for the Bucks over the Boston Celtics.

That improved the Bucks, who sit third in the Eastern Conference, to 22-13 for the season. It was the fifth time this season that Antetokounmpo has topped 35 points in a game.

Christmas Curry proves a rare treat

Heading into the Golden State Warriors' game with the Phoenix Suns, Stephen Curry was averaging a meagre 13.1 points in his eight career games on Christmas. That ranked as his worst average points haul on any date he has played on more than twice.

This time Curry came good though, bagging a game-high 33 points in a 116-107 win for the Warriors.

There was cause for Christmas cheer for the New York Knicks' Kemba Walker too. The Knicks landed a 101-87 win over the Atlanta Hawks, led by Julius Randle's 25 points and 12 rebounds, with Walker weighing in with the team's first triple-double on Christmas Day. He finished with 10 points, 10 rebounds and 12 assists, and on the right side of the scoreboard.

Milwaukee Bucks superstar Giannis Antetokounmpo has reportedly been cleared from the NBA's health and safety protocols.

Finals MVP Antetokounmpo entered the league's COVID-19 protocols on December 15 and has missed five games. 

According to ESPN, he will decide on Friday whether he is fit enough to feature in the Bucks' clash with the Boston Celtics on Christmas Day.

Antetokounmpo has been averaging 27.0 points, 11.6 rebounds and 5.8 assists per game for the defending champions this season.

He is shooting 53.0 per cent from the field – his lowest number since the 2017-18 season, and 28.0 per cent from three-point range.

The Bucks (21-13) are third in the Eastern Conference, behind the Brooklyn Nets (21-9) and Chicago Bulls (19-10).

Joe Johnson celebrated his return to the NBA in style on Wednesday, marking a two-minute appearance with the final two points of the game as the Boston Celtics beat the Cleveland Cavaliers 111-101.

Johnson, a seven-time All-Star, was signed up by the Celtics on Wednesday on a 10-day contract, after the league granted the team a hardship waiver due to the rising amount of COVID-19 cases across the competition.

The 40-year-old has now played in 1,277 career NBA games over what is now an 18-season career, though he had last featured for the Houston Rockets in 2018.

Having joined the Celtics in the 2001 Draft as the 10th overall pick, he was let go after his rookie season, but still enjoyed a stellar career. 

Across 17 seasons from 2001 to 2018, Johnson averaged 16.0 points per game, 4.0 rebounds and 3.9 assists.

He also recorded five successive campaigns of averaging over 20.0 points per game, during a seven-season stint with the Atlanta Hawks.

When he came on for his cameo against the Cavaliers, Johnson became the second-oldest player currently in the NBA, behind Udonis Haslem of the Miami Heat.

Johnson was dubbed "Iso Joe" due to his prowess in one-v-one situations throughout his career, and the veteran showed that skill had not gone away as he outjumped Justin Anderson to add the final two points onto Boston's score on Wednesday.

"It's amazing to be back here 20 years later," Johnson, who is the only current NBA player to have played against the legendary Michael Jordan, told reporters.

"It's still surreal to me. To come into the game and be somewhat effective, that's fun.

"At my age you try to relish every moment, enjoy the process and live in the moment. That's kind of what I'm doing right now, living in the moment and it's fun."

Johnson knows, however, that he has been given an unlikely opportunity.

"I wouldn't say give up, but I didn't have high hopes," Johnson added. 

"My son's 14, so he keeps me in the gym. We work and work and work, and I always talk to him [and say], "just work". Even when you can't see what's next, you just gotta continue to work."

Johnson was only notified of the possible deal with the Celtics on Tuesday, and shortly after was on a flight to Boston.

"It was a no-brainer for me," he said. "I'm a guy who really takes care of his body. I'm in pretty good shape. So I felt like I was ready to take on that challenge.

"So [my agent] asked me what I thought, and we just kept moving. I'm ready for whatever comes my way."

"He's still got a lot in the tank if you ask me," said Jaylen Brown, who scored a team-leading 34 points for Boston.

"I've watched him in the Big3, I've watched him before that, and I watched him growing up and he still looks like he's got something left in the tank so I'm happy to have him on board, to hear his voice, his advice. I think it's great."

Jrue Holiday and Khris Middleton rose in the absence of Giannis Antetokounmpo as the Milwaukee Bucks defeated the Houston Rockets 126-106 on Wednesday.

The reigning champions were without Antetokounmpo for the fourth straight game after he entered the NBA's health and safety protocols last week.

The Bucks had lost their last two without their Greek star but Holiday finished with 24 points, 10 assists and four rebounds, while Middleton added 23 points and six assists on his return from a knee injury.

Young small forward Jordan Nwora hit four triples in his 18-point haul, while center Christian Wood had a double-double for the Rockets with 20 points and 11 rebounds.

The win improves the Bucks to a 20-13 record and third spot in the Eastern Conference.

Brown shines for Celtics

Jaylen Brown scored 16 first-quarter points to finish with 34 for the game including five three-pointers as the Boston Celtics got past the Cleveland Cavaliers 111-101. Darius Garland had 28 points and six assists for the Cavs.

Paul George recorded five steals along with 17 points and six assists as the Los Angeles Clippers finished strong to beat the Sacramento Kings 105-89.

The depleted Atlanta Hawks went down 104-98 to the Orlando Magic, despite Cam Reddish's season-high 34 points.

Jokic silenced by the Thunder

Reigning MVP Nikola Jokic had a rare quiet night with only 13 points, seven rebounds and three assists as well as three turnovers as the Denver Nuggets went down 108-94 to the Oklahoma City Thunder. Shai Gilgeous-Alexander (27 points, 11 rebounds, 12 assists) had a second career triple-double for OKC.

Philadelphia 76ers head coach Doc Rivers labelled Joel Embiid "awesome" after a remarkable 41-point performance in their 108-103 win over the Boston Celtics on Monday.

Embiid finished the game with 41 points, 10 rebounds, five assists, two steals and four blocks in a dominant display.

It marked Embiid's third game of at least 40 points, 10 rebounds, five assists and four blocks, which is the second-most since blocks became official in 1973-74, behind only Kareem Abdul-Jabbar's four.

Embiid also went past Charles Barkley with his sixth career game of at least 40 points, 10 rebounds and five assists.

"He was awesome," Rivers said at the post-game news conference. “He took his shots. What we talk about with him every day, make or miss, just get your shot. Get the shot you want. I thought he did that.

"I thought Seth [Curry] did that as well. Our execution down the stretch was absolutely perfect. The spacing, I think we got two threes off their spacing out the post. [It] was perfect. That was pretty good.”

Embiid had good support from both Tobias Harris (25 points, seven rebounds and three assists) and Seth Curry (26 points, four rebounds and seven assists).

However, the Cameroonian center got the 76ers over the line with 17 points in the final quarter, including a clutch late shot in the corner under pressure.

"That's a shot that we work on every single day," Embiid said at the post-game news conference. "So that's a shot that I just didn't pull out of nowhere. We worked on it so many times.

"I saw the double team coming, and at that point, there had been a couple of times where I got doubled and we didn't cut quick enough, and I had no passing lanes and I ended up turning the ball over. So, in that situation, I thought I had a great angle and I had been making shots. I thought it was a great shot."

The win improves the 76ers' record to 16-15 but they are still well off the pace set by the Brooklyn Nets (21-9) in the Eastern Conference.

"I gotta do it every night," Embiid said. "Right now, it's a lot tougher because we got a bunch of guys out and haven't been winning. So that was one that we needed."

Joel Embiid inspired the Philadelphia 76ers to a thrilling 108-103 road win over the Boston Celtics with 41 points including 17 in the fourth quarter on Monday.

Embiid's remarkable final period also included a steal from a last-ditch Celtics inbound with 3.9 seconds on the clock and the 76ers leading 106-103.

The 76ers center made 14 of 27 shots from the field (52 percent) and collected 10 rebounds, five assists, two steals and four blocks.

Tobias Harris (25 points, seven rebounds and three assists) and Seth Curry (26 points, four rebounds and seven assists) provided good support for Embiid.

Jayson Tatum had a down game for the Celtics, only managing 17 points, while Jaylen Brown scored 30 points with five rebounds and four assists.

Draymond's season-first triple-double

Stephen Curry scored 30 points including four three-pointers but Draymond Green (16 points, 11 rebounds and 10 assists) stole the show with his first triple-double of the season as the Golden State Warriors beat the Sacramento Kings 113-98. Green also had two blocks and two steals.

Dejounte Murray became the first player in San Antonio Spurs history to reach six triple-doubles in one season, with 24 points, 12 rebounds and 13 assists as they won 116-92 over the Los Angeles Clippers. Paul George returned from an elbow injury with 25 points, six rebounds and six assists for the Clippers.

Rudy Gobert dominated with 23 points and 21 rebounds as the Utah Jazz improved to 21-9 with a 112-102 win over the Charlotte Hornets. LaMelo Ball (21 points, 11 assists and six rebounds) and Miles Bridges (21 points and 11 rebounds) were good for the Hornets.

Grizzlies cannot win with Morant

Ja Morant could not lift the Memphis Grizzlies upon his return from injury, managing only 16 points in a 102-99 loss to the Oklahoma City Thunder, who had rookie Josh Giddey (19 points and 11 assists) impress. The Grizzlies bizarrely went 10-2 without Morant during his three-week absence, having been 9-10.

Fred VanVleet starred as the Toronto Raptors won 119-100 over the Golden State Warriors who rested star guard Stephen Curry on Saturday.

VanVleet finished with 27 points, seven rebounds and 12 assists as the Raptors blew the Warriors away in the first half, leading 63-42.

Curry (rest), Draymond Green (right hip), Andre Iguodala (right knee), Otto Porter Jr. (left foot) and Andrew Wiggins (left knee) were all absent for Golden State and returned to California to avoid potential COVID-19 exposure and quarantine in Canada.

The Raptors made their absence count, shooting 45 of 90 from the field, becoming the first side the Warriors have allowed this season to shoot at 50 percent or better.

The Warriors' sixth defeat of the season leaves them second in the Western Conference with a 24-6 record.

Wizards end Jazz run

Bradley Beal scored a season-high 37 points and had seven assists and five rebounds as the Washington Wizards ended the Utah Jazz's eight-game winning streak 109-103. Donovan Mitchell scored 32 points for the Jazz, while Rudy Gobert had 19 rebounds with 11 points.

Cedi Osman came off the bench to top score for the Cleveland Cavaliers with 23 points as they won 119-90 over the Milwaukee Bucks, who were missing Giannis Antetokounmpo due to COVID protocols.

Luke Kennard's (27 points, seven rebounds) heroics could not lift the Los Angeles Clippers to victory, going down 104-103 to the Oklahoma City Thunder, who were led by rookie Josh Giddey (eight points, 18 rebounds, 10 assists).

Weakened Nets lose to struggling Magic

The depleted Brooklyn Nets, missing star trio Kevin Durant, Kyrie Irving and James Harden due to COVID protocols, were beaten 100-93 by the lowly Orlando Magic for their sixth win of the season. The loss was the Nets' ninth.

Stephen Curry posted 30 points as the Golden State Warriors reclaimed the best record in the NBA with a 111-107 victory at the Boston Celtics.

Curry – the league's all-time three-points leader – nailed five shots from beyond the arc to fuel the Warriors (24-5) on Friday.

The Warriors snapped a five-game losing streak against the Celtics as Andrew Wiggins added 27 points.

It was a milestone victory for head coach Steve Kerr, who became the third coach in franchise history to reach 400 career wins.

"We're coming off the emotional roller coaster ... a lot going on around the league," Curry said after Jordan Poole entered the NBA's COVID-19 protocols. "You try not to get distracted by all the things that are outside the locker room."

Lillard's 43 inspires Blazers

Damian Lillard torched the Charlotte Hornets with a season-high 43 points to help the Portland Trail Blazers end a seven-game losing streak by winning 125-116. Lillard was 12 of 19 from the field as he posted the 40th 40-point game of his career.

The San Antonio Spurs upstaged the Utah Jazz 128-126 behind Dejounte Murray's second triple-double in three games – 16 points, 11 rebounds and 11 assists. San Antonio did not commit a turnover in the third quarter and registered a season-high 41 points in that period to snap Utah's eight-game winning run.

Reigning MVP Nikola Jokic fell just short of a triple-double after scoring 20 points, collecting 10 rebounds and tallying seven assists in the Denver Nuggets' 133-115 win against the Atlanta Hawks. Trae Young's 34 points and 10 rebounds were not enough for the Hawks.

LeBron's Lakers beaten

LeBron James was five-of-13 shooting for 18 points and 10 rebounds in the Los Angeles Lakers' 110-92 defeat at the Minnesota Timberwolves. Isaiah Thomas had 19 points in his second Lakers debut as Karl-Anthony Towns inspired the Timberwolves with 28 points and 10 rebounds.

Not even a career-high 40 points from Jrue Holiday could lift defending champions the Milwaukee Bucks, who went down 116-112 to the New Orleans Pelicans after overtime in the absence of stars Giannis Antetokounmpo and Khris Middleton.

Stephen Curry moved within two three-pointers of breaking Ray Allen's all-time NBA record as the Golden State Warriors edged the Indiana Pacers 102-100 on Monday.

Curry finished the game with 26 points including five triples to close in on Allen's record of 2,973 three-point attempts made. The two-time MVP will look to break the mark on Tuesday against the New York Knicks.

Domantas Sabonis scored 30 points with 11 rebounds for the Pacers, who led late before Curry, who shot at 33 percent from beyond the arc, hit his fifth three-point attempt to narrow the margin.

Curry had another attempt from beyond the arc rim out, with Kevin Looney's putback giving Golden State the lead with 13.4 seconds left.

Gary Payton II's defense on Caris LeVert forced a late turnover to seal the win for the Warriors who improve to 22-5, ahead of Curry's next attempt at breaking the record in New York.

Tatum downs depleted Bucks

Jayson Tatum hit seven three-pointers as he finished with 42 points in the Boston Celtics' 117-103 victory over the Milwaukee Bucks. The reigning champions lost Khris Middleton to a left knee hyper-extension in the third quarter, while Giannis Antetokounmpo was kept relatively quiet with 20 points, eight rebounds and three assists.

The Philadelphia 76ers missed Joel Embiid who was out with rib soreness, going down 126-91 to the Memphis Grizzlies, while reigning MVP Nikola Jokic led the Denver Nuggets past the Washington Wizards 113-107 with 28 points, 19 rebounds and nine assists.

Trae Young scored 41 points with nine assists but it could not prevent the Atlanta Hawks from losing 132-126 to the resurgent Houston Rockets. Eric Gordon netted 32 points for Houston who came from 19 points down with a 38-21 fourth quarter.

CP3 struggles as Suns stumble

Chris Paul could not find his stride against his former franchise, struggling for nine points shooting at under 30 percent with eight assists in the Phoenix Suns' 111-95 loss to the Los Angeles Clippers. The Suns, who are 21-5, were without Deandre Ayton and Devin Booker.

Khris Middleton suffered a hyperextended left knee in Monday's 117-103 loss to the Boston Celtics which the Milwaukee Bucks are praying is not a serious injury.

Middleton landed awkwardly upon contact with team-mate Rodney Hood attempting to rebound late in the third quarter, before limping off the court moments later after trying to play on.

Bucks head coach Mike Budenholzer said they would wait until Tuesday to make a determination on the severity of the injury to the 2020-21 NBA champion.

"I think we're terming it a left knee hyper-extension," Budenholzer said at the post-game news conference.

"We'll know more tomorrow but I think there's some hope it's not serious, but you've got to wait and give it time."

Middleton had four points with eight rebounds and three assists on the night, succumbing to injury after 24 minutes on court.

The 30-year-old small forward is averaging 18.6 points, 5.6 rebounds and 5.0 assists per game this season. Middleton averaged 20.4 points in the Bucks' title-winning season.

The defeat to the Celtics leaves the reigning champions with an 18-11 record and third spot in the Eastern Conference.

Giannis Antetokounmpo scored 41 points on Friday and had a triple-double on Sunday but managed only 20 points with eight rebounds and three assists.

"I think we've got to space around him a little bit better," Budenholzer said. "Move him a little bit more. It was a tough night for us, sometimes that happens."

Budenholzer also refused to blame the Bucks' recent heavy schedule with three games in four days.

"Credit to Boston, they played well tonight," he said. "I think we weren’t at our best. Whatever the reasons are, we've got to be better."
