The Cleveland Cavaliers will be without star guard Donovan Mitchell for Game 4 of their second-round play-off series against the Boston Celtics on Monday.

The Cavs ruled Mitchell out about an hour before tip-off due to a left calf strain.

Cleveland also ruled out center Jarrett Allen, who will miss his seventh straight game with a rib injury.

The Cavaliers are facing a 2-1 series deficit to the NBA-best Celtics. In Cleveland’s Game 2 win, Mitchell contributed 29 points, seven rebounds and eight assists.

Mitchell, who sustained his calf injury late in Saturday’s Game 3 loss, is averaging 29.6 points this post-season, including a combined 89 points in Games 6 and 7 of the Cavs’ first-round series against the Orlando Magic.

Earlier in the day, backcourt mate Darius Garland told reporters that it would be important for others to attack if Mitchell were sidelined.

“Just be aggressive,” Garland said. “Play as a team, keep the ball moving and trust each other. We have a lot of guys that are super confident in themselves, so we'll need them to be super confident tonight and make the extra pass and play as a team and pull us together.”

Jaylen Brown praised the Boston Celtics for proving to themselves they are "not here to play around" in their 106-93 victory over the Cleveland Cavaliers in Game 3.

The Celtics' win on Saturday edged them into a 2-1 lead in the Eastern Conference semifinals after losing Game 2 with a defensive performance Brown described as "unacceptable".

At Cleveland, they bounced back - Jayson Tatum had 33 points and 12 rebounds, while Brown added 28 points as the Celtics avoided a second consecutive defeat.

"I think we just need everybody to be on the same page and everybody to come out with the right effort," Brown said.

"That's 85% of the battle right there. We come out, we play hard, and then we're on the same page and the rest will take care of itself. We got enough talent in the locker room to beat teams.

"But if we're not on the same page, and we're not playing hard, those are when we get ourselves in trouble. So making sure, before the game at film and shootaround, talking to everybody, touching everybody, letting everybody know that 'Hey, we're not here to play around.'

"We didn't come to Cleveland for the weather, so let's go.

"It's the playoffs. Anything can happen, especially if you come out flat. We've got to do a better job of that, we can't think like this series is going to go like last series.

"We've got to come out and have the same defensive effort going into Game 4 and that's just the urgency we need to have."

Donovan Mitchell starred for Cleveland, scoring 33 points, but was forced off late in the game due to a knee injury, and despite showing signs of a comeback, they could not find any answers in the fourth quarter.

"I just think we didn't hit the same shots we did [in Game 2]," Mitchell said.

"For us, just being able to finish. We missed a lot of shots at the rim, myself included, missed a lot of shots that I think we just got to make. And also, we didn't really shoot that great from 3, but not a bad per cent, but we didn't shoot that well.

"So I think those are different things, and we got to get our looks and take them, because if we don't, we're driving back into the crowd, and they want us to. So being able to take our shots when they're open."

Donovan Mitchell scored 16 of his 29 points in the third quarter and the Cleveland Cavaliers answered with a blowout of their own in a 118-94 win over the Boston Celtics to even their second-round playoff series at one game apiece on Thursday.

Evan Mobley had 21 points and 10 rebounds and Caris LeVert added 21 points off the bench for the Cavaliers, who won their first road playoff game in five tries this postseason.

Cleveland lost the series opener on Tuesday by 25 points but seized the lead in the third quarter with Mitchell sinking four of five from 3-point range. He hit three straight baskets early in the fourth, including a 28-foot, banked 3 to make it 95-80.

Boston never got the deficit under double digits after that.

Jayson Tatum scored 25 points and Jayen Brown added 19 but combined to shoot 14 for 34, including 2 for 11 from 3-point range for the Celtics, who were 8 for 35 from beyond the arc.

Derrick White was limited to 10 points and misfired on seven of eight from deep after he had 25 points in Game 1.

Boston center Kristaps Porzingis missed his third straight game with a strained calf muscle.

Mobley started at center in place of Jarrett Allen, who has missed the last five games with bruised ribs.

Mavericks beat Thunder to even series

Luka Doncic had 29 points, 10 rebounds and seven assists in a bounce-back performance as the Dallas Mavericks defeated the Oklahoma City Thunder, 119-110, to even their second-round series at a game apiece.

P.J. Washington had 29 points with seven 3-pointers and grabbed 11 rebounds and Tim Hardaway Jr. scored 17 points off the bench for Dallas, who will host Game 3 on Saturday.

After he was limited to 19 points on 6-of-19 shooting in Game 1, Doncic was 11 of 21 from the field and 5 for 8 from 3-point range in this one.

Shai Gilgeous-Alexander had 33 points, 12 rebounds and eight assists and Jalen Williams added 20 points for the Thunder, who lost for the first time in six playoff games and allowed over 100 points for the first time this postseason.

Gilgeous-Alexander's layup with 7:13 remaining drew the Thunder within 106-101, but Doncic hit a pair of jumpers and Washington dunked to make it 112-101 with 4:14 to play.  

Donovan Mitchell scored 16 of his 29 points in the third quarter and the Cleveland Cavaliers answered with a blowout of their own in a 118-94 win over the Boston Celtics to even their second-round playoff series at one game apiece on Thursday.

Evan Mobley had 21 points and 10 rebounds and Caris LeVert added 21 points off the bench for the Cavaliers, who won their first road playoff game in five tries this postseason.

Cleveland lost the series opener on Tuesday by 25 points but seized the lead in the third quarter with Mitchell sinking 4 of 5 from 3-point range. He hit three straight baskets early in the fourth, including a 28-foot, banked 3 to make it 95-80.

Boston never got the deficit under double digits after that.

Jayson Tatum scored 25 points and Jayen Brown added 19 but combined to shoot 14 for 34, including 2 for 11 from 3-point range for the Celtics, who were 8 for 35 from beyond the arc.

Derrick White was limited to 10 points and misfired on 7 of 8 from deep after he had 25 points in Game 1.

Boston center Kristaps Porzingis missed his third straight game with a strained calf muscle.

Mobley started at center in place of Jarrett Allen, who has missed the last five games with bruised ribs.

Mavericks beat Thunder to even series

Luka Dončić had 29 points, 10 rebounds and seven assists in a bounce-back performance as the Dallas Mavericks defeated the Oklahoma City Thunder, 119-110, to even their second-round series at a game apiece.

P.J. Washington had 29 points with seven 3-pointers and grabbed 11 rebounds and Tim Hardaway Jr. scored 17 points off the bench for Dallas, which hosts Game 3 on Saturday.

After he was limited to 19 points on 6-of-19 shooting in Game 1, Doncic was 11 of 21 from the field and 5 of 8 from 3-point range in this one.

Shai Gilgeous-Alexander had 33 points, 12 rebounds and eight assists and Jalen Williams added 20 points for the Thunder, who lost for the first time in six playoff games and allowed over 100 points for the first time.

Gilgeous-Alexander's layup with 7:13 remaining drew the Thunder within 106-101, but Doncic hit a pair of jumpers and Washington dunked to make it 112-101 with 4:14 to play.  

Jaylen Brown hailed the growth of "aggressive" Derrick White, who continued his impressive postseason form in the Boston Celtics' victory over the Cleveland Cavaliers.

The pair scored a combined 57 points as the Celtics prevailed 120-95 in Game 1 of their Eastern Conference semi-finals series at TD Garden.

White notched up seven three-pointers - going four-for-six in the third quarter - as he became only the fifth player in NBA history to make 20 or more over a three-game span in the postseason, after Stephen Curry, Klay Thompson, Jamal Murray and Damian Lillard.

And Brown, who was 12-for-18 shooting to go with six rebounds, two assists and just one turnover, paid tribute to his team-mate as the Celtics improved to 5-1 in the playoffs.

"Derrick has grown," Brown said. "He's a new version that we haven't seen before.

"He's put the work in, his body has developed a little bit, he's got some more playoff experience. He's being aggressive, and we urge him to do that more and more down the line."

Asked if he felt like he was in a rhythm, White said: "I'd say so. It feels good. I just want to help us win."

Meanwhile, Donovan Mitchell's haul of 33 points and six assists proved academic for the Cavaliers, who suffered their fourth successive road defeat in the postseason.

J.B. Bickerstaff, whose side came through an epic seven-game series against Orlando Magic in the opening round on Sunday, saluted the efforts of his players.

"There's a lot of areas we can improve on," he said. "I thought the guys came out with the right intent and the right effort. Facing a team like Boston, I think it's good to be able to play them.

"You're not used to the speed, the spacing, the shooting and all those things until you get up against them - especially coming from a series we just came from that was more of a half-court slugfest, where they play with more tempo and more space. We'll learn from it, and we'll be better."

Shai Gilgeous-Alexander had 29 points, nine rebounds and nine assists and the top-seeded Oklahoma City Thunder kept Luka Dončić in check to pull away for a 117-95 victory in Game 1 of their Western Conference semifinal series on Tuesday.

Chet Holmgren had 19 points and seven rebounds and Jalen Williams scored 10 of his 18 points in the fourth quarter as the Thunder remained unbeaten in the playoffs.

Game 2 is Thursday night in Oklahoma City.

Doncic entered this series averaging just under 30 points per game in these playoffs but was limited to 19 on 6-of-19 shooting, including 1 of 8 from 3-point range, and had five turnovers.

Kyrie Irving led Dallas with 20 points and Daniel Gafford had 16, 11 rebounds and five blocks.

The Thunder held just a 69-67 lead midway through the third quarter before a 20-7 run increased the advantage to 89-74.

Dallas got the deficit down to 96-87 on Irving’s 3 with 8:31 remaining, but Williams hit consecutive 3s and then dunked to make it 104-87.

Celtics handle Cavs in Game 1

Jaylen Brown scored 32 points and Derrick White added 25 with seven 3-pointers to lead the Boston Celtics to a 120-95 win over the Cleveland Cavaliers in the opener of their Eastern Conference second-round series.

Jayson Tatum had 18 points and 11 rebounds and Payton Pritchard scored 16 for the Celtics, who improved to 5-1 in this postseason and will host Game 2 on Thursday night.

Donovan Mitchell had 33 points and six assists and Evan Mobley added 17 and 13 rebounds as Cleveland lost for the fourth time in as many road playoff games.

Boston shot 18 of 46 from 3-point range and took a 15-point lead into the fourth quarter. The Celtics started the final quarter with a 10-2 run to essentially put the game out of reach.

Both teams played without their starting centres. Cleveland’s Jarrett Allen missed his fourth straight game with a bruised rib and Boston’s Kristaps Porzingis was sidelined for the second consecutive game with a strained right calf.

Jayson Tatum claimed that the Boston Celtics are learning from their mistakes after securing their place in the Eastern Conference semifinals.

The Celtics are into the semifinals following a 4-1 series victory over the Miami Heat after winning Game 5 118-84 on Wednesday.

In taking the series, the Celtics avenged their 2023 Conference finals loss to the Heat, who routed them in Game 7.

Tatum praised the team’s attitude during the win, saying: "That's how it should be.

"We should be learning from our mistakes and things we could've done better and applying it to the next season, because we're trying to have a different outcome this year."

Jaylen Brown and Derrick White each scored 25 points, while Sam Hauser had 17 points and Tatum added 16 with 12 rebounds for the Celtics.

Despite a record-breaking shooting performance by the Heat in Game 2, they struggled to gain a foothold in the series. They missed 26 of 29 from 3-point range and were out-rebounded 56-29 in Game 5 while playing without the injured Jimmy Butler, Terry Rozier and Jaime Jaquez Jr.

The Celtics were also without a key player, as Kristaps Porzingis missed his first postseason game with a right calf strain that will keep him out for at least a week.

Brown insisted that the Celtics have proven that they were never reliant on any single player.

"I think we just have to continue to play our game like we've been doing our whole career and continue to show our growth by trusting our teammates," he said.

"I think if we're going to win, we're going to win as a team."

Up next for the top-seeded Celtics is the winner of the Cleveland-Orlando series that the Cavaliers lead 3-2.

Al Horford said that the Boston Celtics needed to change their mindset after losing Kristaps Porzingis to injury during their convincing Game 4 102-88 victory over the Miami Heat.

The Celtics now have a 3-1 series lead after Derrick White scored a career-high 38 points to edge the top seeds one step closer to the Conference Semifinals.

The win came at a cost though, as Porzingis was forced off with right calf tightness just before the end of the second quarter, but the Celtics rallied to win their sixth straight game in Miami.

Horford replaced Porzingis for the second half and told ESPN that the team had to change their approach after losing a key player.

“All of us, our mindset has to shift," he said.

“I talked to Luke [Kornet] and Xavier [Tillman] and let them know that all of us have to be ready to step up and do a little more because KP was playing so well defensively.

“It’s definitely concerning for me. He's in good spirits, but we don't know what it's going to be. I'm just hoping that it's nothing serious, and he can get back to us quick.”

Bam Adebayo finished with 25 points, 17 rebounds and five assists for Miami, but they struggled on offence once more, with Tyler Herro scoring 19 points and Caleb Martin adding 18.

The Heat coach, Erik Spoelstra, bemoaned his side’s struggles to get more points on the board, saying: “Offensively, we struggled again. We had some decent looks early on, weren't able to knock those down, and Derrick White was very good tonight — obviously. He was just very efficient, very good.

“I know in my heart we have a game that's there. It's just a matter of the ball going in a few more times, and all of a sudden it ignites.”

Despite playing through a calf strain, Jamal Murray hit a pull-up 14-footer with 3.6 seconds remaining, and the Denver Nuggets beat the Los Angeles Lakers 108-106 on Monday for a 4-1 series win.

Murray, who also hit a buzzer-beater to win Game 2, was a game-time decision due to his calf injury but scored 12 of his 32 points in a fourth quarter in which the teams repeatedly traded leads.

LeBron James hit a pair of free throws to tie the game with 26 seconds left to give the Lakers hope, but Murray drove to his left with help from a high ball screen and pulled up for the go-ahead jumper over Austin Reaves.

Without any timeouts to advance the ball, the Lakers managed only a desperation heave from Taurean Prince at the buzzer which never had a chance.

Much like last year, when the Nuggets swept the Lakers in the Western Conference finals, Denver’s late-game execution proved to be the difference.

Nikola Jokić finished with 25 points, 20 rebounds and nine assists, while Michael Porter Jr. concluded his impressive series with a 26-point performance.

James led the Lakers with 30 points and 11 assists. Anthony Davis had 17 points and 15 rebounds but was not involved much in the offence late while playing through a shoulder injury.

The Nuggets will continue their championship defence with a second-round series against the Minnesota Timberwolves, who advanced Sunday by completing a sweep of the Phoenix Suns.

Denver eliminated Minnesota in the first round of last year’s playoffs with a five-game series win.

Thunder complete sweep of Pelicans

Shai Gilgeous-Alexander and Jalen Williams each scored 24 points to lead the Oklahoma City Thunder to a 97-89 win over the New Orleans Pelicans and secure a four-game series sweep.

The youngest team ever to secure a conference’s No. 1 seed, the Thunder answered questions about play-off inexperience by easily securing their place in the second round, outscoring New Orleans by an average of 15.8 points per game.

Oklahoma City trailed 71-70 to start the fourth quarter but held the Pelicans to 18 points in the final frame.

Williams scored 11 of his points in the fourth quarter, including his own 8-0 run that put the Thunder up 93-82 with 3:08 remaining.

The Pelicans played the series without Zion Williamson due to a hamstring strain, with Brandon Ingram and CJ McCollum failing to rise to the challenge.

Ingram shot under 35 percent from the field during the series and was 2 of 14 in Game 4. McCollum had 20 points on 9-for-16 shooting Monday but was just 7 of 29 from 3-point range in the series.

Celtics rout Heat for 3-1 series lead

Derrick White scored 38 points, and the Boston Celtics overcame an injury to Kristaps Porzingis to beat the Miami Heat 102-88 for a 3-1 series lead.

Porzingis exited with 2:27 remaining in the second quarter with right calf tightness and did not return. Al Horford started the second half in Porzingis’ place.

White, who is better known for his defensive contributions, went 8 of 15 from 3-point range en route to his 38 points, a career high for both the regular season and post-season.

Bam Adebayo led the way for the Heat with 25 points, 17 rebounds and five assists.

Jayson Tatum believes his Boston Celtics team showed their toughness as they claimed a 104-84 Game 3 win over the Miami Heat on Saturday.

As the top seed in the Eastern Conference, Boston eased to victory in the opening match of the first-round series. However, the eighth-seed Heat hit back in Game 2, taking a 111-101 triumph to level the series.

Game 3 belonged to the Celtics, though, with a strong defensive display and a big performance from Tatum, who finished with 22 points and 11 rebounds, allowing Boston to once again get their noses in front ahead of Game 4.

In Tatum's view, the Celtics were able to match their ability with a strong mindset in Game 3 to help them regain control of the series.

"Everybody knows how talented we are," Tatum told reporters. "But can we be the tougher, harder-playing team?"

"If we can combine that with the talent, it's going to be hard to beat us.

"Can we start off every game, essentially, punching first instead of reacting? That's a test we have to be up for every single night."

The Heat hit 23 3-pointers in their Game 2 victory, but the Celtics' defensive display was a big improvement on Saturday, limiting the Heat to just 84 points.

Miami head coach Erik Spoelstra acknowledged the Celtics' much-improved performance in Game 3, though he still believes his team has the ability to haul themselves back into the series again.

"They were the more physical team," Spoelstra explained. "They bodied us [and] bullied us.

"We have enough to get the job done. We know we have to play hard, and we also have to play well."

The Miami Heat are desperate to silence their doubters and are using outside criticism as fuel in their first-round playoff series against the Boston Heat, having levelled it up at 1-1.

That is according to forward Bam Adebayo, who had 21 points and was nine of 13 shooting in the Heat's 111-101 win at TD Garden on Wednesday.

Miami buried their hosts under a mountain of 3-pointers in Game 2, setting a franchise record for a postseason game by shooting 23 of 43 (53.5 per cent) from the field.

Speaking after the game, Adebayo said the way in which the Eastern Conference's eighth seeds have been written off by neutrals was spurring them on.

"We've been doubted a lot through our playoff runs, people saying we couldn't do a lot of stuff that we eventually did," Adebayo said.

"So for me and my team, why lose belief now? Our backs are against the wall. Everybody's against us. So just use that as fuel.

"Our guys believe we can win. So, let's make it mano a mano… a cage fight. Let's hoop!"

Caleb Martin joined Adebayo on 21 points with five 3s, being booed by the Boston crowd every time he touched the ball following his heavy collision with Jayson Tatum in Game 1.

Jaime Jaquez Jr. contributed 14 points with three 3s, Nikola Jovic added a trio of 3s and Haywood Highsmith came off the bench to sink three 3s.

Martin said Miami's new shoot-on-sight mentality was part of a plan drawn up by Erik Spoelstra, saying: "I think it was about realising that being passive hurts us. 

"We'd just be playing into their gameplan. We're too good of a shooting team to hesitate from 3."

Spoelstra himself said the Heat had taken the decision to be more proactive after being sunk by Boston's 3-point shooting in Game 1.

"I understand the math of it," the Miami coach said. "We're not going to shoot 50 of them. That's not realistic."

Tyler Herro had 24 points and 14 assists and hit six of Miami’s franchise playoff-record 23 3-pointers as the Heat defeated the Boston Celtics, 111-101, to even their first-round series at a game apiece on Wednesday.

Bam Adebayo had 21 points and 10 rebounds and Caleb Martin added 21 points with five 3s for the Heat, who shot 53.5 percent (23 of 43) from long range to break the franchise playoff record of 20 3s, set against Milwaukee in 2021.

Jaime Jaquez Jr. contributed 14 points with three 3s, Nikola Jovic added a trio of 3s, nine rebounds and six assists and Haywood Highsmith came off the bench to hit three 3s.

The series shifts to Miami for Games 3 and 4 on Saturday and Monday.

Jaylen Brown scored 33 points and Jayson Tatum added 28 for the top-seeded Celtics, who cut Miami’s lead to 102-96 with three minutes left. But Martin hit a 3 and Herro made a driving layup to essentially seal the win.

Tatum scored 14 points in the first quarter and showed no ill effects after he was undercut by Martin while going after a rebound in the final minute in Game 1.

Gilgeous-Alexander, Holmgren power Thunder

Shai Gilgeous-Alexander scored 33 points and Chet Holmgren added 26 to lead the hot-shooting Oklahoma City Thunder to a 124-92 rout of the New Orleans Pelicans and a 2-0 lead in their Western Conference first-round series.

Jalen Williams had 21 points, seven assists and five rebounds for the Thunder, who shot 59 percent (46 for 78) from the floor and made 14 of 29 (48.3 percent) from 3-point range.

Game 3 will be Sunday in New Orleans.

Jonas Valanciunas had 19 points and Herbert Jones and Brandon Ingram each added 18 as the Pelicans continued to struggle offensively without injured star Zion Williamson (strained left hamstring).

New Orleans missed 19 of 26 from beyond the arc and made 33 field goals to 46 for Oklahoma City.

Jayson Tatum showed he was unfazed by the Miami Heat's physicality as he logged his first career playoff triple-double in the Boston Celtics' 114-94 Game 1 victory on Sunday.

Top-seeded Boston seized the initiative in their first-round series against Miami at TD Garden, with Tatum adding 10 rebounds and 10 assists to his 23 points, leading six Celtics in double figures.

Tatum's fine performance came despite some rough treatment from the Heat, taking one huge hit from Caleb Martin while going up for a rebound in the last minute of the fourth quarter.

Martin immediately went to help Tatum up but was pushed by Boston's Jaylen Brown, with both players awarded technicals. The Miami forward later said the incident was accidental, as he received a slight nudge from Jrue Holiday before crashing into Tatum.

The five-star All-Star was soon back to his feet, though, and he later said getting hit was just part of the game. 

"It's playoff basketball, and it's a physical game against a physical team. ***'s going to happen," Tatum said. "It's probably not the last time I'm going to get hit like that in this series.

The Celtics led by as many as 34 points in the fourth quarter, with a late run from the Heat only ever bringing them as close as 14. 

Tatum hailed Boston for staying focused throughout, adding: "It's supposed to be tough. In the playoffs no game is easy. 

"There are no guaranteed wins regardless of the score, or how much time is left. We just had to respond and we did that."

Miami struggled in the absence of Jimmy Butler, and coach Erik Spoelstra accepted they were second-best, saying: "Boston controlled this game from the tip. 

"They won the big muscle areas. They definitely won the 3-point line and the majority of the areas in between."

Elsewhere on Sunday, Milwaukee Bucks star Damian Lillard scored 35 first-half points – a franchise playoff record – as they claimed a 109-94 victory over the Indiana Pacers in Game 1 of their own first-round series.

Lillard didn't score after halftime, but his lightning start ensured the Bucks were untroubled despite the absence of two-time NBA MVP Giannis Antetokounmpo, who missed out with a calf strain. 

Milwaukee built a commanding 69-42 lead by the interval and never saw their advantage drop to single digits as Khris Middleton tacked on 23 points – 15 of them in the second half.

Looking ahead to Tuesday's second game, which will also be held at the home of the third-seeded Bucks, Lillard said: "In the playoffs, it's about setting the tone.

"We're going to see this team a lot of times, and you want to establish yourself, especially on your home floor. That was my mentality, to come out and try and set the tone in that way."

Remarking on Lillard's incredible first-half performance, Milwaukee coach Doc Rivers said: "He carried us. He was unbelievable."

Over the course of four quarters, Lillard was upstaged by Indiana's Pascal Siakam, who finished with 36 points and 13 rebounds in 40 minutes on the court.

Indiana head coach Rick Carlisle, however, was unable to look beyond their miserable start to the game.

"The first half was embarrassing," Carlisle said. "We have no excuses. We've simply got to come out better. It was ugly, and we all own it."

James Harden scored 28 points to help the Los Angeles Clippers overcome Kawhi Leonard's absence and come through with a 109-97 victory over the cold-shooting Dallas Mavericks in Sunday's Game 1 of a Western Conference quarter-finals series.

Harden and Ivica Zubac each stepped up with the fourth-seeded Clippers missing Leonard due to inflammation in his surgically repaired right knee. Zubac set a play-off career high with 20 points while grabbing 15 rebounds, while Harden went 6 of 11 from 3-point range in addition to dishing out eight assists.

Los Angeles also used a strong defensive effort to gain the upper hand in this best-of-seven series. Fifth-seeded Dallas shot just 38.8 per cent for the game and especially struggled in the

second quarter, missing 19 of 21 field goal attempts while being outscored by a 22-8 margin for the period.

The Clippers took a commanding 56-30 half-time lead behind their dominant second quarter, as they held the Mavericks' star duo of Luka Dončić and Kyrie Irving to a combined 17 points on 5-of-19 shooting over the first two periods.

Irving regrouped in the second half to finish with 31 points. Doncic compiled 33 points, 13 rebounds and six assists, but the NBA MVP finalist ended 11 of 26 from the field and 4 of 12 from 3-point range.

Paul George added 22 points for Los Angeles, which shot 50 per cent (18 of 36) from 3-point range compared to 30.3 per cent for Dallas.

Game 2 will take place Tuesday in Los Angeles.

 Lillard carries Bucks past Pacers with Antetokounmpo still unavailable

The Milwaukee Bucks were also able to withstand the loss of a superstar in their series opener, as Damian Lillard set a franchise play-off record with 35 first-half points to lead the way in a 109-94 Game 1 win over the Indiana Pacers.

Lillard didn't score after half-time, though his prolific performance through two quarters was more than enough to give Milwaukee, the Eastern Conference's No. 3 seed, a 1-0 series lead despite Giannis Antetokounmpo still recovering from a strained left calf he sustained late in the regular season.

The two-time league MVP's absence wasn't a major factor thanks in large part to Lillard, who tallied 19 first-quarter points as the Bucks opened up a 30-21 lead after 12 minutes before breaking the game open in the second.

Lillard put up 16 more points in the second quarter as Milwaukee outscored the Pacers by a 39-21 margin for the period to build a sizeable 69-42 lead at the break.

Khris Middleton scored 15 of his 23 points after half-time to keep the Bucks ahead by double digits the entire second half.

Middleton added 10 rebounds and Bobby Portis also notched a double-double with 15 points and 11 boards.

Sixth-seeded Indiana received 36 points and 13 rebounds from Pascal Siakam, but the Pacers shot just 20.5 per cent (8 of 39) from 3-point range and never led after the game's initial stages.

Indiana will attempt to bounce back in Tuesday's Game 2, which will again be held in Milwaukee.

 Celtics cruise past Butler-less Heat in series opener

The Miami Heat, on the other hand, had a far more difficult time dealing with two key players missing as the defending Eastern Conference champions were dealt a 114-94 loss by the top-seeded Boston Celtics in Game 1 of the teams' quarter-finals series.

Jayson Tatum registered his first career play-off triple-double with 23 points, 10 rebounds and 10 assists to lead Boston, which lost in seven games to Miami in last season's East finals. 

Derrick White added 20 points and Kristaps Porzingis had 18 as Boston never trailed against an eighth-seeded Miami team playing without six-time All-Star Jimmy Butler and starting guard Terry Rozier.

Butler is likely out for the series after injuring his right knee during the play-in round, while Rozier has missed the Heat's last seven games with a neck strain.

Boston set the tone right from the start by opening the game on a 17-2 run. Miami later countered with a 9-0 spurt to cut its deficit to 26-23 early in the second quarter, but that was as close as the Heat would get the rest of the day.

The Celtics answered with an 11-2 run to go back ahead by double digits, and their lead swelled to 60-45 at half-time as Tatum scored 10 points in the second quarter and reserve Sam Hauser drained four 3-pointers during the period.

Boston kept pouring it on after the break, as it built a 91-59 advantage after three quarters.

Bam Adebayo led Miami with 24 points, while Delon Wright hit all five of his 3-point attempts in a 17-point effort off the bench.

The series resumes Wednesday in Boston.

 Top-seeded Thunder hold off Pelicans in series opener

Shai Gilgeous-Alexander scored 28 points and converted a tie-breaking three-point play with 32.5 seconds left to play as the top-seeded Oklahoma City Thunder held on for a 94-92 win over the New Orleans Pelicans in the opener of another Western Conference quarter-final series.

Playing their first post-season game since 2020, the Thunder prevailed despite eighth-seeded New Orleans rallying from a 10-point deficit early in the fourth quarter to tie the contest with under four minutes remaining.

The Pelicans, who were without star forward Zion Williamson due to a left hamstring strain, had a chance to pull out the victory but CJ McCollum missed a 3-point try shortly before the buzzer.

Oklahoma City appeared to have seized control after ending the third quarter on a 9-2 run to take a 74-68 lead entering the fourth. The margin later grew when Chet Holmgren buried a 3-pointer with 10:25 remaining that gave the Thunder an 82-72 advantage.

New Orleans answered with a 9-2 spurt to get back in it and later pulled even when Herb Jones' 3-pointer created an 88-88 tie with 3:58 left.

The game remained deadlocked at 90-90 until Gilgeous-Alexander was fouled while knocking down a short floater with 32.5 seconds on the clock. The NBA MVP finalist made the ensuing free throw for a three-point Oklahoma City edge.

McCollum, who finished with 20 points, hit a jumper on the subsequent possession, and the Thunder gave New Orleans a chance at the lead when Holmgren made just 1 of 2 free throws after being fouled with 14 seconds left.

The Pelicans got the ball to McCollum with time winding down, but the veteran misfired on a contested 30-foot shot as Oklahoma City hung on.

Jalen Williams added 19 points for the Thunder, who will host Game 2 on Wednesday, while Holmgren posted 15 points and 11 rebounds.

New Orleans was led by Trey Murphy's 21 points, while Jonas Valanciunas pulled down 20 rebounds to go along with 13 points. 

Kristaps Porzingis suggested Thursday's defeat to the New York Knicks could be just what the Boston Celtics needed ahead of the playoffs.

The Celtics went down 118-109 to the Knicks, as New York hunt down the No.2 seed in the Eastern Conference.

Boston have long since had their playoff berth secured, but have now lost their last two games.

Porzingis, though, is taking the positives.

"It stings to have this loss, but maybe we need this before heading into the postseason with a killer mentality," Porzingis said.

"It's not who we are. This is not the team our fans love. That wasn't on display.

"You best believe we'll show up when we have to. We know what the goal is and make no mistake about it."

Jaylen Brown chipped in with 15 points for the Celtics, and like Porzingis, recognises Boston have not been up to scratch as of late.

"We got out-toughed the last two games and haven't played to our standard," Brown said.

"The game has shifted and it's going to shift even more in the playoffs."

Jalen Brunson led the Knicks with 39 points, and New York are now just one game behind the Milwaukee Bucks in the race for the No.2 seed.

"We made shots and made the right plays," Brunson said.

"Obviously, we know they're the top dog in the East. Whenever you play against them, it's always a good measuring stick to see where you're at.

"We played pretty well, but we know what they’re capable of doing. We just had their number tonight."
