Luka Doncic will not play for the Dallas Mavericks against the Chicago Bulls after he was ruled out with a right quad strain following Friday's loss to the Milwaukee Bucks.

The three-time All-Star, who currently leads the NBA for points per game with a 32.9 average this season and sits second on the scoring charts outright, complained of pain during his side's 106-105 defeat.

With a three-game home run set to start on Monday against the Oklahoma City Thunder, the call has been made to keep Doncic sidelined for this weekend's trip to United Center.

It is not yet known if there is further reason to be concerned for the point guard, who has been in scintillating form across the campaign so far.

In addition to Doncic, Maxi Kleber and Josh Green will miss Saturday's match with the Bulls, after they also picked up injuries against the Bucks at American Airlines Center.

The forward is out with right foot soreness, while the guard has suffered a right elbow sprain.

The Mavericks arrive in Chicago having suffered their first loss in four, with defeat to the Bucks snapping a three-game victorious run over the New York Knicks, the Phoenix Suns and the Denver Nuggets.

Doncic has topped the points chart for his team in all but one of those games, scoring 33 on Friday in addition to 11 assists and six rebounds. 

His efforts have guided the Mavericks to seventh in the Western Conference this season, with a 13-12 winning record to date.

Darvin Ham credited the Los Angeles Lakers' resolve after they fell to a 133-122 loss against the Philadelphia 76ers, praising his team for refusing to fold.

The Lakers fought back multiple times over the course of the game to ultimately force overtime at 120 apiece, before their hosts eked out victory at the Wells Fargo Center.

A 31-point haul for Anthony Davis, aided by 25 for Austin Reaves and 23 for LeBron James, was not enough for the Lakers to stave off a third consecutive defeat.

However, Ham was in a bullish mood when quizzed on his team's performance, saying there were plenty of positives to take away despite their stinging reverse.

"We can get better from this," he stated. "I told the team, as disappointed as I am that we didn't get the win, I still can have a good meal and sleep like a baby tonight because of the way we competed.

"We did not quit, we did not give up. There was a point in the game where we could've just folded our tent.

"But we kept scratching away, kept digging deep, kept making plays one stop after another one and put ourselves in a position to win the game."

Meanwhile, 76ers coach Doc Rivers said his side rallied well to seize victory after letting their initial lead slip on several occasions.

"We will take the win," he added. "Usually when you give up a lead like that, to gather yourself and play well in overtime is rare."

The Lakers will round off their road stretch against the Detroit Pistons on Sunday, before heading home to face the Boston Celtics.

No De'Aaron Fox, no worries for the Sacramento Kings, as they defeated the Cleveland Cavaliers 106-95 on the road to improve their record to 14-10.

Fox leads the Kings in scoring at 22.8 points per game and could be on track for his first All-Star appearance, but he missed just his second game of the season on Friday with right foot soreness.

His absence was balanced out by the Cavaliers missing Donovan Mitchell, but with the Cavaliers still rolling out All-Stars Darius Garland and Jarrett Allen, as well as Rookie of the Year runner-up Evan Mobley, they still had more than enough firepower.

But, lacking a true number-one scoring option, the Kings turned the contest into a slow, low-scoring grind, relying on excellent outside shooting to maximise their limited possessions and pull away with a 27-15 fourth quarter, including a 19-0 run to end the game.

Four of the Kings starters scored at least 18 points each, with Harrison Barnes' 20 points finishing as a team-high, while Domantas Sabonis played a superb all-round game to post 18 points, 18 rebounds, six assists, three steals and two blocks.

As a team, Sacramento shot 16-of-33 (48.5 per cent) from three-point range, and six of those makes came from rookie Keegan Murray, scoring all 18 of his points from beyond the arc on just eight attempts.

Speaking after the game, head coach Mike Brown spoke about how it feels to take a road win against the team sitting third in the Eastern Conference.

"That was a big, big, big-time win for us," he said. "When you get a win like that on the road, that’s a sign you have a really good team. 

"Now, I hope I’m not jumping the gun on that, but this was my favourite game of the season."

Harrison Barnes added: "To come here after losing to Milwaukee, we kind of wanted to make a statement – and we did."

The Kings have now won 11 of their past 15 games, and have a chance to break into the top-four in the Western Conference if they can handle their business in Madison Square Garden against the New York Knicks on Sunday.

Kevin Durant and Kyrie Irving eclipsed 30 points each in the Brooklyn Nets' 120-116 home win over the Atlanta Hawks on Friday.

It was also the return of Ben Simmons after a five-game stint on the sidelines, starting and contributing six points, seven assists, six rebounds and four steals in 21 productive minutes.

Durant top-scored with 34 points on 14-of-25 shooting, while Irving was just as good, scoring 33 on 11-of-21 shooting while chipping in 11 rebounds.

Mostly known for his offense, Durant blocked two shots, raising his season average to 1.7 per game – the eighth-best figure in the league.

Trae Young was solid for the Hawks with 33 points (12-of-25 shooting) and nine assists, but he committed a game-high eight turnovers. He is the only player in the NBA averaging at least 25 points (27.2) and nine assists (9.5).

With the win, the Nets have now taken six of their past seven, improving their record to 15-12 after starting the season 1-5.

Pelicans stay top of the West

Entering the game as the top two teams in the Western Conference, the New Orleans Pelicans rode a terrific Zion Williamson performance to a 128-117 win against the Phoenix Suns.

Williamson was unstoppable offensively, scoring a game-high 35 points on 13-of-17 shooting, adding seven rebounds and four assists. Of his 20 games this season, it is the ninth time he has scored at least 25 points on 60 per cent shooting.

There are 14 players shooting 59 per cent or better from the field this season, and of those, only Anthony Davis is averaging more field goal attempts per game (17.5) than Williamson's 15.4.

Embiid's early dominance almost goes to waste

Joel Embiid tied the Los Angeles Lakers' whole team in the first quarter with 20 points each, but the Philadelphia 76ers needed an overtime period to come away with a 133-122 win.

Embiid was eight-of-nine from the field in the first quarter for his 20 points, going on to finish with 38 on 14-of-19 shooting, 12 rebounds and five assists. Teammate De'Anthony Melton helped out with a career-high 33 points on 11-of-16 shooting, hitting eight of his 12 three-point attempts.

Anthony Davis continued his strong form with 31 points (nine-of-13 shooting) and 12 rebounds, but he missed a potential go-ahead free throw in the final seconds, before the Lakers were outscored 13-2 in overtime.

Julius Randle looks back to his best as he led the New York Knicks to a 121-102 victory against the Charlotte Hornets on Friday for his side's third consecutive win.

Randle, 28, is slowly rediscovering the form that saw him named to the All-NBA Second Team for the 2020-21 season, rebounding from a slow start to this campaign.

After averaging 18.3 points on 43.8 per cent shooting in October, Randle raised that to 22.2 points per game at 47.1 per cent shooting in November, before taking another step forward in the Knicks' current December winning streak.

In the Knicks' three wins this month, Randle is averaging 25.3 points, 10.3 rebounds and 4.0 assists while shooting 47.2 per cent from the field and 37.0 per cent from deep on a gaudy nine attempts per contest.

He had a game-high 33 points against the Hornets, hitting four-of-10 from three-point range, while R.J. Barrett produced an efficient 26 points (nine-of-18 shooting) and Jalen Brunson set it all up with 11 points and 11 assists.

Speaking to the media after the game, Barrett kept it short and to the point when hyping up Randle.

"He's cooking," he said. "We need him to keep doing that."

Head coach Tom Thibodeau was willing to expand further on what exactly has changed in Randle's play, and he pointed to his overall effort, including the plays that do not make the highlight reel.

"[Randle] had a play where he was behind the play, beat everyone down the floor, pulled everyone in, and we ended up getting a three on it," he said. "There’s no stat for that, other than it helps you create rhythm for your team. 

"He’s made several plays like that when he’s getting double-teams, getting off the ball, moving without the ball, he’s screening off the ball. He’s playing a great all-around game. 

"I think that helps set the tone for the team. I thought we played very unselfishly."

Randle believes his terrific form is primarily about his mindset.

"I'm just being aggressive and taking what the defense is giving me," he said. "I'm playing with confidence.

"It's a lot of fun and everybody is in a rhythm. The energy is contagious."

The Knicks have now pulled their record even at 13-13, and are tied with the Atlanta Hawks for the seventh-best record in the Eastern Conference.

The Utah Jazz will receive a boost for Friday's home game against the Minnesota Timberwolves in the form of Mike Conley Jr's return from a nine-game injury absence.

Conley, 35, has not played since November 19, when he left the floor against the Portland Trail Blazers after only playing nine minutes, going on to be diagnosed with a strained muscle near his left knee.

An All-Star in 2021, Conley is posting his lowest point average (10.2 per game) since his rookie season, although his 7.9 assists per game is a new career-high in his 16th campaign.

Speaking to reporters after Friday's shootaround, he implied he was not yet at full capacity, but that the only way he is going to get to that point is by returning to game-speed.

"I've been working, and we're still working through some things, but the only way to get through it is to kind of work your way back in it and test the water," he said.

After trading away franchise players Rudy Gobert and Donovan Mitchell in the offseason, it was meant to be a rough rebuilding year for the Jazz, but they have defied expectations up to this point and sit sixth in the Western Conference at 15-13.

The Cleveland Cavaliers have given their leading scorer Donovan Mitchell the night off Friday, opting to rest the three-time All-Star against the Sacramento Kings on the first night of a home back-to-back.

Mitchell has been nursing an ankle injury for weeks after initially spraining it against the Golden State Warriors on November 11, before tweaking it again on November 28 against the Toronto Raptors.

He missed one game following the Warriors injury, and did not miss any time following the aggravation against the Raptors, averaging 33.3 points per game in the Cavs' three contests leading up to Friday.

But after listing him as questionable for the meeting against the Kings, Cleveland have opted to play it safe and give their new superstar a rest day. Mitchell will likely return for Saturday's home fixture against the Oklahoma City Thunder.

Suiting up for 23 of the Cavs' 25 games this season, Mitchell's 29 points per game is the seventh-highest figure in the league, and a new career-high after being traded from the Utah Jazz in the offseason for a bevy of draft picks.

His 42.4 per cent three-point shooting on 9.1 attempts per game has him as one of the league's best shooters this season, as only Stephen Curry (43.2 per cent on 11.8 attempts) is eclipsing 40 per cent on at least nine attempts per game.

Starting in his place will be Caris LeVert, who is averaging 12.1 points, 5.1 assists and 4.9 rebounds in his 14 starts this campaign, while All-Star point guard Darius Garland will be tasked with an increased scoring burden.

Jamal Murray earned plaudits for his "complete basketball game" after hitting the last-gasp three-pointer that earned the Denver Nuggets a 121-120 win over the Portland Trail Blazers.

The impressive road win saw the Nuggets improve to 15-10 for the season and halt a streak of three defeats.

Murray's step-back game-winner came with less than a second remaining, capping a 21-point game, two nights after he shot just 2-of-11 from the field against the Dallas Mavericks.

Reigning back-to-back MVP Nikola Jokic was also a force for the Nuggets with 33 points (14-of-25), 10 rebounds and nine assists, while Damian Lillard scored a game-high 40 points for Portland.

Lillard put the home team two points ahead with a stunning three-pointer with nine seconds remaining, but Murray brought the late twist.

Nuggets coach Michael Malone said: "It was great to see Jamal find his rhythm. Coming off a game against Dallas where I think he was really frustrated with his offense, not making shots the way he knows he's capable of making shots.

"I started him in that fourth quarter, and I was planning on taking him out to bring him back, but once Jamal sees the ball go in it doesn't take many for him to catch fire, and he ran the whole fourth quarter, obviously. [He had] 21 points, eight assists, only two turnovers, five rebounds – a complete basketball game.

"It was an understatement to say a much-needed win after losing three in a row. I thought our fourth-quarter defense was outstanding, 21 points allowed. As I told our players, when we don't turn the ball over and we defend, we're a really good team. Now the challenge is to do that a lot more consistently. A lot of guys stepped up and played well."

DeAndre Jordan played the 1,000th game of his NBA career, and Malone paid tribute to that achievement, saying of the 34-year-old center: "I'm really thankful that he's here and a part of our family."

Murray, meanwhile, felt the Trail Blazers, who dominated the third quarter 35-26, were brilliantly reined in by the Nuggets in the closing stages.

He told Altitude TV: "They came out hot in the second half, but we knew if we wanted to win the game we had to play defense together as a unit, especially with this crowd, so I think we did a good job of that.

"Dame got hot. It was our defense down the stretch. We were able to stay together, keep our unit together and get some stops down the stretch.

"We know they're going to make shots, especially on their home floor. We couldn't get down on ourselves and keep that negative energy. Go to the next play and figure it out."

Bam Adebayo said the Miami Heat were determined to "dig ourselves out of a hole" after his starring role lit up a 115-110 win against the Los Angeles Clippers.

The Heat center put in a dominant 31-point performance in Thursday's success that followed two defeats in a row for Miami, who are 12-14 for the season and 10th in the Eastern Conference.

As they look to put together a run of healthy results, Adebayo said it would need to be a collective effort by the team to achieve their goals.

He told Bally Sports in an on-court interview: "We're trying to dig ourselves out of a hole. The biggest thing is we stand connected, stand together, and we keep waking up trying. We wake up and try to find solutions every day."

Adebayo weighed in with 10 rebounds and four assists, shooting 14-of-21 from the field, while the Heat got the job done from 87-84 behind going into the fourth quarter.

After failing to reach the 30-point mark in each of his first 13 games this season, Adebayo has now reached that figure in four of his past 11 outings, raising his season average to a career-high 21.2 points per game.

The 25-year-old said: "My team-mates want me to be assertive. They want me to look for my shots. They're finding me in the pocket. The biggest thing I can do is keep shooting."

Asked about the key to seeing out victory over the Clippers, who sit ninth in the Western Conference, gave credit to Jimmy Butler, who made 10 of his 12 field attempts on his way to 26 points, eight assists, five rebounds and four steals.

"We gave Jimmy the ball," said Adebayo. "He's our closer, so we let him do his thing down the stretch."

Miami Heat center Bam Adebayo did not attempt a single shot from outside the key on his way to a dominant 31-point performance in Thursday's 115-110 win against the Los Angeles Clippers.

Adebayo also added 10 rebounds (four offensive) and four assists, shooting 14-of-21 from the field in a tremendously efficient outing as the Clippers' interior defense had no answers.

After failing to reach the 30-point mark in each of his first 13 games this season, Adebayo has now eclipsed the figure in four of his past 11 fixtures, raising his season average to a career-high 20.7 points per game.

He was supported in style by Jimmy Butler, who hit 10 of his 12 field goal attempts for a terrific game in his own right, posting 26 points, eight assists, five rebounds and four steals.

Paul George led the way for the Clippers, and was the only reason they were able to keep things close on the road while Kawhi Leonard was out for a scheduled rest day, scoring a team-high 29 points (10-of-20 shooting) with eight rebounds and seven assists.

The victory for the Heat snaps a two-game losing streak and pulls their record back to 12-14, leaving them 10th in the Eastern Conference, while the Clippers are ninth in the West at 14-13.

Johnson and the Spurs win all-Texas showdown

The San Antonio Spurs received standout performances from Keldon Johnson and Tre Jones to defeat in-state rivals the Houston Rockets 118-109.

Johnson finished one point off his season-high with 32 on 14-of-21 shooting, hitting half of his six three-point attempts, while Jones' 26 points on 10-of-16 shooting was a new career-high.

Despite the loss, it was a strong outing from this year's third overall pick in the NBA Draft, with Jabari Smith Jr scoring a career-high 23 points on nine-of-13 shooting. The six-foot-11, smooth-moving wing showed off his special shooting stroke, hitting four-of-seven from deep.

'Dame Time' not enough against the Nuggets

Damian Lillard scored 15 of his game-high 40 points in the final six minutes, but Jamal Murray had the last laugh as the Denver Nuggets outlasted the Portland Trail Blazers 121-120.

Lillard, in his second game back from injury, looked back to his best late in the fourth quarter, hitting a contested step-back three with nine seconds on the clock to go up by two. He ended up shooting 12-of-22 for his 40 points and 12 assists, hitting at least nine three-pointers for the 10th time in his career.

But Murray would hit his own step-back game-winner with less than a second remaining, putting a bow on his 21-point, eight-assist showing, while reigning back-to-back MVP Nikola Jokic was a force with 33 points (14-of-25), 10 rebounds and nine assists.

Atlanta Hawks All-Star Dejounte Murray will spend the next two weeks on the sideline after the extent of his injury was revealed on Thursday.

Murray could only make it through four minutes of the Hawks' 113-89 loss to the New York Knicks on Wednesday, leaving in the first quarter after tweaking his left ankle. 

After an MRI on Thursday, the team announced he has been diagnosed with an ankle sprain and is dealing with the associated swelling, and his status will be updated when his condition improves.

Murray became a first-time All-Star this past season with the San Antonio Spurs, averaging 21.1 points, 9.2 assists and 8.3 rebounds per game to carry his side to the play-in tournament.

His emergence, combined with the Spurs going into rebuild mode, resulted in the Hawks swooping in with an offer centred on three future first-round draft picks, and Murray has shown his breakout was no fluke.

Despite playing alongside All-NBA point guard Trae Young, Murray's production has remained strong, as he is second on the Hawks for points (20.8) and assists (6.2), while leading the team in steals (1.8 per game).

His absence adds to a growing injury list for Atlanta, which now includes three starters as John Collins (ankle sprain) and De'Andre Hunter (hip flexor strain) remain out.

Brittney Griner has been released from Russian prison and the two-time basketball Olympic gold medallist will be back in America in the next 24 hours, US president Joe Biden said.

At the White House, President Biden confirmed he had spoken to 32-year-old Griner, who was arrested at Moscow's Sheremetyevo International Airport on February 17 for bringing under a gram of cannabis oil into Russia in vape cartridges.

That was shortly before Russia invaded Ukraine, weakening diplomatic relations with the US, and eight-time WNBA All-Star Griner was jailed for nine years in August for drug possession and drug smuggling with criminal intent.

Griner said she made an "honest mistake", and her lawyers argued she was using cannabis for medicinal purposes to treat chronic pain sustained over the course of her career.

They said she was not aware cannabis oil was outlawed in Russia.

Reports in the United States said Griner had been freed in a prisoner exchange that has seen arms dealer Viktor Bout released into Russian hands.

President Biden said Griner had been "unjustly detained in Russia", describing circumstances she endured as "intolerable".

"Brittney will soon be back in the arms of her loved ones, and she should have been there all along," Biden said. "This is a day we've worked towards for a long time."

Biden said there had been "painstaking and intense negotiations". He said recent months had been "hell for Brittney" and stressed efforts were ongoing to free former US Marine Paul Whelan, who is in a Russian jail after being convicted in 2020 on espionage charges.

Biden said Phoenix Mercury player Griner was "in good spirits" and "relieved to be heading home" after enduring "needless trauma".

She was "wrongfully detained" in the first place, Biden said, and he added: "She endured mistreatment and a show trial in Russia with characteristic grit and incredible dignity.

"She wrote to me back in July, she didn't ask for special treatment, even though we'd been working on her release since day one."

Griner's wife Cherelle appeared alongside Biden and said: "Over the last nine months y'all have been so privy to one of the darkest moments of my life."

She said news of Griner's release left her "overwhelmed with emotions", and she offered "sincere gratitude" to Biden and his administration.

"Today it's just a happy day for me and my family," she added.

Klay Thompson admitted he "fell asleep" as the Utah Jazz produced a stunning finish to snatch a dramatic 124-123 win over the Golden State Warriors on Wednesday.

The Warriors roared back from 11 points down in the fourth quarter to lead by four with only 13.3 seconds to play at Vivint Arena.

Golden State paid the price for switching off in the closing stages, though, leaving Malik Beasley on his own in the right corner to give him the chance to land a three-pointer.

Simone Fontecchio then came up with a decisive dunk with 1.4 seconds to go after Utah forced a turnover from Jordan Poole.

Thompson held his hands up for not paying close attention to Beasley.

"I just fell asleep," Thompson said. "I watched the ball handler get to the rim rather than sticking on the three-point shooter. That was a dreadful mistake by myself."

Poole, who scored 36 points and provided eight assists, was at a loss to explain what happened late on.

"I heard on the catch, 'Look for the foul on the ball'," Poole said. "I don't really know [what happened], to be honest."

Warriors head coach Steve Kerr expects his team to learn from a shattering defeat.

"I feel terrible for our guys because they fought and they did a lot of great things, but we have to close the door," Kerr said.

"I thought [we] really fought and earned the right to win the game, and then we didn't close. And you've got to close.

"You've got to be rock solid with the ball. You've got to be smart defensively. We were neither of those things the last 13 seconds."

Golden State are 10th in the Western Conference at 13-13 after back-to-back losses, with the 15-12 Jazz four places above them.

Desmond Bane faces longer than expected on the sidelines after it was revealed the Memphis Grizzlies guard may not play again until January.

Struck down by a toe injury, it had been announced on November 15 that the Grizzlies would be without Bane for up to three weeks, but the wait goes on for his return.

An update from the team on Tuesday disclosed he faces up to a further four weeks out of action, and that is provided the toe reacts as the Grizzles hope it will to a gradual recovery process.

Bane has a big toe sprain and a sesamoid injury, which refers to a bone embedded within a tendon or muscle.

He sustained the toe sprain during a win against the Minnesota Timberwolves on November 11.

In a statement, the Grizzlies said: "Upon re-evaluation, Desmond Bane is progressing in his rehabilitation from a right big toe sprain and sesamoid injury and has been cleared to begin a gradual re-loading protocol.

"If the toe responds positively to the re-loading protocol, a return to play is projected in 3-4 weeks."

Bane is averaging a career-high 24.7 points, 4.8 assists and 4.9 rebounds per game for Memphis in an impressive season to date. The team sit third in the Western Conference with a 16-9 record.

The Eastern Conference-leading Boston Celtics had a statement win over the Western Conference-leading Phoenix Suns with a 125-98 blowout victory on Wednesday.

The Celtics led by as much as 45 points and benched MVP candidate Jayson Tatum in the fourth quarter, in a game where the Suns welcomed back All-Star Chris Paul from a heel injury.

Tatum finished with 25 points with five rebounds, two assists and two steals. The 24-year-old is the first player in Celtics history to average 30 points per game in his first 25 games of any season.

Jaylen Brown also scored 25 points with seven rebounds, while Malcolm Brogdon added 16 points off the bench.

Boston led 69-42 at half-time in the blowout win, which was the Celtics' second-biggest margin this season.

Devin Booker struggled with four fouls and three field-goals made in the first half, finishing with 17 points, five rebounds and three assists. Paul had four points and four assists in 24 minutes on his return.

The result means the Celtics improved to an NBA-best 21-5 record after three straight wins, while the Suns fall to 16-9.

Giannis powers Bucks to another win

Giannis Antetokounmpo matched Kareem Abdul-Jabbar for the second-longest streak of consecutive 30-point games (eight) in franchise history as the Milwaukee Bucks downed the Sacramento Kings 126-113.

The Greek forward finished with 35 points on 12-of-19 field-goal shooting, with six rebounds and six assists as the Bucks improved to 18-6 with their third straight win. The victory extended the Bucks' win streak against the Kings to 13.

Bucks guard Jrue Holiday made an excellent contribution with 31 points, five rebounds and six assists, while Kings forward Domantas Sabonis added 23 points with 12 rebounds.

Banchero clutch in Magic OT win

Top overall NBA Draft pick Pablo Banchero showcased his potential to help the Orlando Magic snap their nine-game losing streak with a 116-111 overtime win over the Los Angeles Clippers.

The 20-year-old power forward scored 23 points for the game, including making all six of his free-throws in the final seven seconds of overtime to overturn a 111-110 deficit. The Clippers gave up two turnovers down the stretch.

Paul George and Kawhi Leonard made another rare appearance together again, combining for 17 first-quarter points. George finished with 11 for the game with seven rebounds and five assists, while Leonard added 14 points with seven rebounds and three assists.
