Jaylen Brown led six players in double figures with 22 points and Kristaps Porziņģis had 20 in his first game in over a month as the Boston Celtics pulled away for a 107-89 win over the Dallas Mavericks in Game 1 of the NBA Finals on Thursday night.

Jayson Tatum had 16 points and 11 rebounds and Derick White scored 15 for the Celtics, who improved to 13-2 in the playoffs with their eighth straight win as they seek their 18th NBA title.

Game 2 is Sunday night in Boston.

Porzingis came off the bench and provided an immediate spark in his first game since April 29 due to a strained right calf. He had six rebounds and three blocks in 21 minutes.

Luka Dončić had 30 points and 10 rebounds, but former Celtic Kyrie Irving managed just 12 points on 6-of-19 shooting and missed all five of his 3-point attempts.

Dallas totalled just nine assists on 35 field goals and its scoring total was its lowest of the postseason.

Boston started fast and led by 29 in the first half before Dallas opened the third quarter on a 22-9 run to pull within 72-64 on Doncic’s 3-pointer.

The Celtics responded with the next 14 points, capped by 3s from Tatum, Al Horford and Brown for an 86-64 advantage.

The Boston Celtics will get starting centre Kristaps Porzingis back in the lineup on Thursday when they host the Dallas Mavericks in Game 1 of the NBA Finals.

It was reported Tuesday that he would return, and when asked by reporters on Wednesday, he said he would be back.

"I'll play tomorrow," he said.

The Celtics later submitted their official injury report and he was not included.

Porzingis sustained a right calf strain in Game 4 of the opening round of the playoffs against the Miami Heat on April 29 after averaging 14 points and 5.7 rebounds in the first three meetings.

Al Horford moved into the starting lineup after Porzingis went down and averaged 10.7 points and 7.3 rebounds in 10 games as Boston went 9-1 to reach the NBA Finals for the second time in three seasons.

The Celtics acquired Porzingis from the Washington Wizards last June, and the fourth overall pick of the 2015 NBA Draft averaged 20.1 points and 7.2 rebounds in 57 games for Boston this season.

Porzingis spent part of three seasons with Dallas before being traded to Washington in February 2022.

Jayson Tatum views the upcoming NBA Finals as a chance at redemption for the Boston Celtics after falling short two years ago.

The Celtics swept the Indiana Pacers to reach the showpiece seven-game series, where they face the Dallas Mavericks.

With Game 1 of the much-anticipated series coming on Friday, Tatum looked back at the 2022 Finals defeat to the Golden State Warriors, using the disappointment as motivation this time around.

"It's a lot that myself, and we, can learn from that experience being in the Finals, and this time, this go-around is a lot different," Tatum said after Saturday's practice.

"Obviously, we've been there before, we came up short. And a great opportunity to make it to the Finals again.

"You don't always get a second chance, so really just looking at it as a second chance and trying to simplify things as much as we can."

The Celtics were eliminated in the Eastern Conference finals against the Miami Heat last year, losing in seven games.

That has prevented Boston from avenging their finals defeat to Golden State the year before, though Tatum is keen to make up for lost time.

He will have to do so against former team-mate Kyrie Irving, however.

"Obviously there were some ups and downs, but I think, for me, being a first-, second-year player, being around a superstar, essentially, every day and seeing how to navigate that space," Tatum said.

"And then obviously on the court, he's one of the most talented guys I've ever seen.

"So it seems like a very long time ago, but I've got a lot of great memories from having [Irving] as a team-mate."

The Boston Celtics return to the NBA Finals as a different team to that beaten by the Golden State Warriors two years ago, says their Eastern Conference finals hero Jaylen Brown.

Brown won the Larry Bird Trophy as Eastern Conference finals MVP on Monday, having helped the top-seeded Celtics complete a 4-0 series sweep of the Indiana Pacers.

In Game 4, Brown sank 10 of his 29 points in the fourth quarter as the Celtics recovered from a nine-point deficit with under nine minutes left for a 105-102 victory.

The Celtics have reached the Eastern Conference finals six times in the last eight years but this is just the second time they have progressed to the NBA Finals in that run. They last did so in 2021-22, only to be beaten 4-2 by the Warriors.

Brown believes they have become a better team for that experience, however.

"We feel like we're a different team than we were last year and the year before that," Brown said. 

"I know everybody wants to continue to pigeonhole us with what was happening in the past but we've had a different team every single year, different coaches, we've had like three coaches in the last five years. 

"Still people want to make it seem like it's the same, it's the same, it's the same.

"Time has gone by, experience has been gained and I think we are ready to put our best foot forward."

Jayson Tatum supported Brown with 26 points, 13 rebounds and eight assists on Monday, while Jrue Holiday had 17 points and Derrick White tacked on 16.

"It's special," Tatum said. "Even though we've been there before, most of us have, you don't take it for granted. We were excited.

"It was a hell of a team we just played, they made us earn every single game and we're extremely grateful to move on to the Finals."

Derrick White's tie-breaking 3-pointer with 45 seconds left sent the Boston Celtics into the NBA Finals for the second time in three years with a 105-102 win over the Indiana Pacers in Monday's Game 4 of the Eastern Conference finals.

The top-seeded Celtics, who were ousted in seven games by the Miami Heat in last year's East finals, completed a sweep of this best-of-seven series by rallying from a nine-point deficit with under nine minutes left.

Jaylen Brown led Boston's comeback by scoring 10 of his 29 points in the fourth quarter and coming up with a key late block that preceded White's winning shot. The Celtics also received 26 points, 13 rebounds and eight assists from Jayson Tatum, as well as another strong performance from their backcourt duo of White and Jrue Holiday.

Holiday totalled 17 points and nine rebounds while White had 16 points on 7-of-14 shooting along with a game-high five steals.

The sixth-seeded Pacers were unable to extend the series while playing a second straight game without All-Star guard Tyrese Haliburton, who injured his hamstring in Thursday's Game 2.

Andrew Nembhard led Indiana with 24 points and 10 assists, while Pascal Siakam posted 19 points and 10 rebounds.

The Celtics will face the winner of the Western Conference finals between the Dallas Mavericks and Minnesota Timberwolves, and will host Game 1 on Thursday, June 6. The Mavericks lead that series 3-0 and can advance at home in Tuesday's Game 4. 

A tightly contested game saw neither side lead by more than eight points until the Pacers put forth a 5-0 run, capped by Nembhard's 3-point play with 8:57 left to play, to take a 94-85 advantage.

Indiana led 98-90 with under six minutes to go before the Celtics began catching fire. After Brown hit two free throws and Tatum knocked down a 3-pointer, Holiday drove the lane and was fouled while getting a layup to go down following a made basket by Nembhard. Boston's veteran guard calmly hit the ensuing free throw to bring the Celtics within 100-98 with 3:54 left.

It remained a two-point game until Brown knocked down a floater with 2:40 left to tie the score at 102-102. Shortly thereafter, the All-Star forward rejected Nembhard in the lane as Boston's Al Horford grabbed the rebound with the contest headed towards the final minute of play.

Brown then found an open White in the right corner, and the valued guard drained a 23-footer to send the Celtics ahead.

Indiana had one final chance to force overtime, but Nembhard's 3-point try missed the mark and the Pacers failed to get another shot off. 

The Boston Celtics were indebted to Jrue Holiday after they moved one win away from reaching the NBA Finals with Saturday's victory against the Indiana Pacers.

Holiday converted a three-point play with 38 seconds remaining, then made a game-saving steal as the Celtics overcame an 18-point deficit to beat the Pacers 114-111 for a 3-0 Eastern Conference finals lead.

Indiana's Andrew Nembhard seemed set to claw the Pacers back into Game 3 late on, yet Holiday stepped across for a "trademark steal" to guide his side over the line.

"That's a trademark steal that he always gets with the inside hand," Celtics coach Joe Mazzulla said of Holiday.

"He gets that a lot usually when a guy is coming down the sideline, but he got it in transition. He made a big-time play."

As Nembhard looked to cut inside the court, Holiday suggested he always knew what was coming.

"He's a right-hand driver," the Celtics hero said after the game, "and he'd been very, very aggressive all night."

Nembhard managed 32 points and nine assists but even that brilliance was not enough to outsmart one of NBA's best defensive players.

"I was trying to get a shot up," said Nembhard. "He got in front of me. I lost the ball, slipped. Turnover."

Jayson Tatum impressed for Boston with 36 points, 10 rebounds, 8 assists and no turnovers in 44 minutes, yet he put all the focus on the match-winning Holiday.

"I mean, can't speak highly enough about Jrue," said Tatum. "The ultimate teammate competitor, obviously a champion, wasn't at shootaround today, he was sick.

"Dealing with chills and stuff like that. And we've all been there, how tough that is, to fight through it, and for him to come out there and lay it all on the line for us, make the game-winning play essentially, especially on the defensive end.

"Jrue is just a big-time player, and he made a tremendous play."

The Celtics can clinch their second NBA Finals appearance in three seasons with a win in Game 4 on Monday in Indianapolis.

Jrue Holiday converted a three-point play with 38 seconds remaining, then made a game-saving steal as the Boston Celtics overcame an 18-point deficit to beat the Indiana Pacers 114-111 for a 3-0 lead in the Eastern Conference finals on Saturday night.

The Celtics can clinch their second NBA Finals appearance in three seasons with a win in Game 4 on Monday in Indianapolis.

Jayson Tatum matched his playoff career high with 36 points to go with 10 rebounds and eight assists. Jaylen Brown added 24 points and Al Horford had 23 points with seven 3-pointers to help Boston win its sixth straight playoff game and improve to 5-0 on the road.

Andrew Nembhard scored a career-high 32 points, but Holiday, who was questionable before the game due to an illness, stole the ball from him with 3.3 seconds remaining and Indiana down 112-111.

Indiana had a chance to tie the game but Aaron Nesmith's 3-pointer was off the mark. 

T.J. McConnell had 23 points, nine rebounds and six assists, while Myles Turner and Pascal Siakam added 22 points apiece for the Pacers, who played without All-NBA guard Tyrese Haliburton (left hamstring).

His presence was sorely missed as the Celtics closed the game on a 13-2 run to send Indiana to its first loss in seven postseason home games.

The teams combined to make six 3s in the fourth quarter, with Horford’s seventh of the night drawing Boston within 111-109 with 1:12 to play. Holiday then converted his 3-point play to give the Celtics their first lead since early in the second quarter.

The Indiana Pacers reportedly won't have star Tyrese Haliburton for Game 3 of the Eastern Conference finals against the Boston Celtics on Saturday.

Haliburton exited in the third quarter of Thursday's 126-110 loss at Boston due to a left hamstring injury, and won't be able to play in the first game in Indianapolis, according to Shams Charania and Joe Vardon of The Athletic.

Thursday's defeat dropped the Pacers to 0-2 in the series.

Haliburton experienced pain in the same hamstring earlier this season, missing 10 games in January.

The two-time All-Star had 25 points, 10 assists and made six 3-pointers in 40 minutes in the series opener before playing only 28 minutes in Game 2. He had 10 points on 4-of-8 shooting and eight assists before departing.

With Haliburton out, the Pacers will likely again rely on Pascal Siakam for offence and need Andrew Nembhard and T.J. McConnell to step up.

Joe Mazzulla warned the Boston Celtics that the confidence garnered from taking a 2-0 series lead against the Indiana Pacers is not enough to secure progress.

The Celtics won 126-110 on Thursday to move two games ahead in their Eastern Conference finals series against the Pacers.

Indiana were also dealt a blow when star player Tyrese Haliburton suffered a hamstring injury, which the Pacers will wait agonisingly on.

Yet with the Pacers having overturned a deficit to overcome the New York Knicks in the last round, Celtics coach Mazzulla knows the job is nowhere near done.

"The only thing we should be thinking about is, they were down 2-0 a series Tago and brought it to Game 7," Mazzulla said.

"They do a great job protecting their home court. They're undefeated at home. It's going to take a lot more than confidence to get the job done.

"We have to focus on the details and the execution and the mindset, the things that go into playing against a team like this at home.

"I know they're going to respond so it's up to us to do the same."

Jaylen Brown starred again for the Celtics, finishing with 40 points on the day he missed out on an All-NBA selection.

"We're two games from the Finals," he said when asked about that snub. "So, honestly, I don't have the time to give a f***."

Indiana, meanwhile, face the prospect of having to fight back against the NBA's best team without their key player.

"He does so many things for our team," T.J McConnell said of Haliburton.

"I think everyone has to move the ball more, get in the paint more. The ball movement has to be at another level. He gets 10 assists in his sleep, so it's hard for another person on our team to replicate that. It's a group effort when he goes down."

Pacers coach Rick Carlisle added: "We'll know more [on Friday] and then probably more Saturday."

Jaylen Brown scored 10 of his career playoff high 40 points during a first-half surge and the Boston Celtics pulled away for a 126-110 victory over the Indiana Pacers to take a 2-0 lead in the Eastern Conference finals on Thursday night.

After his 3-pointer with 5.7 seconds left in regulation forced overtime in Game 1, Brown helped Boston turn a five-point deficit in the first quarter into a 15-point second-quarter lead.

The Celtics led 42-27 after that 20-0 run and never relinquished the lead.

Indiana missed nine straight shots and committed four turnovers during the drought that lasted more than six minutes. Brown had 10 points during the run and had 24 by halftime.

Jayson Tatum and Derrick White each scored 23 points and Jrue Holiday had 15 with 10 assists for the top-seeded Celtics, who lost Game 2 in both of their previous series this postseason.

The series shifts to Indiana for Game 3 on Saturday night.

Pacers star guard Tyrese Haliburton had 10 points and eight assists before leaving in the third quarter with a sore left leg.

Pascal Siakam led Indiana with 28 points and Andrew Nembhard added 16.

The Pacers got as close as 68-66 on Siakam’s 3 with 7:55 left in the third quarter, but Derrick White and Tatum dunked and White made a 3 a minute later to give the Celtics a 75-68 advantage.

Brown’s 3 with 4:32 to go in the third extended the lead to 80-71 and Indiana would get no closer.

Jaylen Brown hailed the Boston Celtics' never-say-die attitude after his last-gasp 3-pointer teed up their overtime win in Game 1 of the Eastern Conference finals.

The Indiana Pacers were just 6.1 seconds away from a 117-114 road win in the opening game of the series on Tuesday, only for Brown to sink a 3 over Pascal Siakam from the corner to level things up.

Two Tyrese Haliburton free throws put the Pacers back in front in overtime, but Jayson Tatum scored 10 of his game-high 36 points in the additional period as Boston triumphed 133-128.

Jrue Holiday supported Tatum with 28 points, while Brown added 26. All three players finished with three steals apiece as Indiana committed 21 turnovers.

Speaking after the dramatic finale, Brown said: "Welcome to the NBA playoffs! You've just got to manage your emotions. Anything can happen. 

"It's not over until the final buzzer sounds. It's not over until it’s over. We found a way to win the game at the very end."

Holiday echoed those sentiments, adding: "We've seen crazy stuff happen all the time. 

"We don't think we've lost a game until we've actually lost the game. That's part of the reason why we were so resilient towards the end.

"A couple of turnovers, a great shot, a great look by JB, or at the other end if we make a couple other shots that were wide open it could be a completely different game. 

"We're just the type of team that's going to keep on fighting no matter how long and no matter what it takes."

The Celtics host Game 2 on Thursday as they target a first NBA Finals appearance since 2021-22, when they were runners-up to the Golden State Warriors.

Asked how Boston will approach Game 2, Tatum said: "Don't relax, it'll be different circumstances. The first two rounds we won our Game 1 by a wide margin, so maybe human nature played into that. 

"But tonight being a close game, going into overtime, we certainly felt like we should have won and we could have played better."

Jayson Tatum scored 10 of his 36 points in overtime and the Boston Celtics capitalised on some sloppy play by the Indiana Pacers for a 133-128 victory in Game 1 of the Eastern Conference finals on Tuesday night.

Jrue Holiday had 28 points and Jaylen Brown added 26, none bigger than his tying 3-pointer with 6.1 seconds left in regulation.

The Celtics finished with 11 steals - three each by Brown, Tatum and Holiday. They became the first team in NBA playoff history to have three players record 25 points and three steals in a game. 

Game 2 is Thursday night in Boston.

Tyrese Haliburton had 25 points and 10 assists for the Pacers, who scored 56 points in the paint against a Celtics team missing injured 7-footer Kristaps Porziņģis. The Pacers, though, committed 21 turnovers.

Indiana twice turned the ball over with a three-point lead in the final 30 seconds of regulation. Brown’s 3 from the corner with Pascal Siakam in his face tied it at 117.

Tyrese Haliburton sank three free throws after he was fouled with 1:46 to go in overtime to put the Pacers ahead 123-121, but Tatum completed a three-point play 34 seconds later to give Boston the lead for good.

Tatum’s 3 following another Indiana turnover with 43 seconds left extended the lead, and he hit two free throws with nine seconds left to seal the win.

Jayson Tatum believes the Boston Celtics' return to the Eastern Conference finals shows the character of the team.

Boston beat the Cleveland Cavaliers 113-98 on Wednesday to book their place in the Conference finals for a third straight season.

It is the sixth time in the past eight years that the Celtics have reached the finals.

"It just shows the character of the team, the organisation," said Tatum, who led Boston with 25 points, 10 rebounds and nine assists.

"People might think that it's a given that we're supposed to be here, but I give a lot of credit to everyone in the front office, the coaching staff, the trainers, the guys that hand out the equipment, the ball boys, the cooks, the chefs, the security team. We're all in this together. I do, I mean that.

"Everybody has an effect on each other, and we all impact each other to help winning and build this culture that we have.

"Everybody should be proud of themselves. Obviously, it's not the end all, be all. We want to win a championship, but we're doing something right."

Coach Joe Mazzulla lauded the mentality and attitude of his team.

"Close-out games are tough. It's a level of stress, anxiety, desperation; it takes what it takes," he said. "You've got to play 48 [minutes] hopefully, maybe more at times.

"And at the end of the day, you just got to keep going, continue to chip away at the things you can control."

The Celtics will face either the New York Knicks or the Indiana Pacers for a place in the Championship game.

Jayson Tatum credited the Cleveland Cavaliers for the fight they showed in Donovan Mitchell's absence after helping the Boston Celtics take a 3-1 lead in the teams' Eastern Conference semifinal series. 

Tatum had 33 points and 11 rebounds as the Celtics moved within a game of reaching the conference finals for a third straight year with Monday's 109-102 road win.

Cleveland, who were already without starting center Jarrett Allen due to a rib contusion, were also deprived of their leading scorer after Mitchell suffered a calf strain in Game 3.

However, the Cavs stayed in the game until Jaylen Brown sank a clutch 3-pointer with 69 seconds to go in the fourth quarter, with Derrick White and Tatum then making a couple of free throws each to add some gloss to the scoreline.

Darius Garland had 30 points and seven assists for the Cavs while Caris LeVert had 19 points, leaving Tatum impressed. 

"It's to be expected, right? When the best player goes out, everybody has more freedom, more opportunity," Tatum said of Boston's opponents.

"Obviously, we knew it wasn't going to be easy. It's the playoffs, they don't want to go home. 

"Give them credit, they played hard from beginning to end and made big plays on both ends. They hit big shots, so it was a battle, and it was fun out there."

Cavs coach J.B. Bickerstaff also heaped praise on his players, saying: "I mean, they laid it all out there. They gave us everything that they had. 

"They competed at a high level. They played the game properly. I'm proud of the guys, the way they went out and scrapped and competed and gave ourselves a chance."

Boston now have a chance to wrap up the series in Game 5 at TD Garden on Wednesday, an opportunity Brown is keen to ensure they take.

"There's nothing better than winning a playoff game on the road," Brown said. "It's like everybody's against you guys. It's a tough environment, the crowd was great, but as a competitor, it's really fun to be in an environment like that, to win on the road.

"Now it's time to go back and play well in front of our fans and give them something to cheer for and try to get a win."

Shai GIlgeous-Alexander scored 22 of his 34 points in the second half to rally the Oklahoma City Thunder from a 14-point deficit and earn a crucial 100-96 victory over the Dallas Mavericks in Monday's Game 4 of a Western Conference semifinal series.

Chet Holmgren had 11 of his 18 points after half-time and added nine rebounds to help the top-seeded Thunder even the best-of-seven series at 2-2 as it heads back to Oklahoma City for Wednesday's all-important Game 5.

The fifth-seeded Mavericks squandered an opportunity to put the Thunder on the brink of elimination despite setting a franchise play-off record with 13 blocks, including four each from Derrick Jones Jr. and rookie Dereck Lively II.

Jones finished with 17 points in the loss, while Luka Dončić registered a triple-double for Dallas with 18 points, 12 rebounds and 10 assists. 

The Mavericks led the majority of the game and owned an 86-80 advantage just past the midway point of the fourth quarter before Oklahoma City began its late surge. The Thunder seized momentum with a 12-2 run, capped by consecutive 3-pointers from Holmgren and Luguentz Dort, to go up 92-88 with 2:14 remaining.

Dallas answered on Tim Hardaway Jr.'s 3-pointer on the ensuing possession, but back-to-back baskets by the Thunder's Jalen Williams gave Oklahoma City a 96-91 lead entering the final minute.

The Mavericks again responded and had a chance to tie it when Doncic was fouled with 10.1 seconds left with Dallas trailing 96-94. The MVP finalist made just one of his two shots, however, and the Thunder sealed the outcome by going 4 for 4 from the foul line in the waning moments.

Free throw shooting played a part in the result, as Oklahoma City finished 23 of 24 from the line compared to 12 of 23 for Dallas.

The Mavericks held a 54-43 lead at half-time after limiting the Thunder to under 35 per cent shooting for the first two quarters, and stretched the margin to 14 when P.J. Washington hit a 3-pointer to begin the third.

Oklahoma City closed the gap before the end of the period, though, as it ended the third quarter on a 9-2 run to pull within 69-65 entering the fourth.

Celtics handle injury-plagued Cavaliers to take 3-1 lead

In the East, the top-seeded Boston Celtics moved within a game of reaching the conference finals for a third straight year after posting a 109-102 Game 4 win over the shorthanded Cleveland Cavaliers behind Jayson Tatum's 33 points and 11 rebounds. 

Jaylen Brown added 27 points to help Boston take a 3-1 series lead over a fourth-seeded Cavaliers team playing without leading scorer Donovan Mitchell. The All-Star guard was unavailable due to a strained left calf he sustained in Cleveland's 106-93 loss in Saturday's Game 3.

The Cavaliers also remained without starting center Jarrett Allen, who hasn't played since Game 4 of their opening-round series against Orlando due to a rib contusion.

Darius Garland kept Cleveland competitive by producing 30 points and seven assists, while Caris LeVert had 19 points starting in place of Mitchell.

Boston can close out the series at home in Wednesday's Game 5.

Tatum set the tone right from the outset, scoring 16 points on 6-of-9 shooting in the first quarter to stake the Celtics to a 37-30 lead after one period.

The All-Star forward closed out the first half with a 3-pointer that sent Boston into the break with a 62-57 advantage, though Cleveland opened the third quarter on an 8-2 run to move ahead by a 65–64 score three minutes into the second half.

Boston re-asserted control from there, however, as it outscored the Cavs by a 14-4 margin over the next 4 1/2 minutes. Brown had seven points during the spurt, which Derrick White capped with a 3-pointer for a 78-69 Celtics' lead with 4:50 left in the third quarter.

The Celtics stretched the lead to 98-83 with under eight minutes left, though Cleveland kept battling and put together a 12-2 run to close the gap to 100-95 with three minutes left to play.

Brown hit a clutch 3-pointer with 1:09 to go, however, to put Boston up 105-97, and the Celtics kept Cleveland at bay the rest of the way as White and Tatum each made two free throws in the closing stages.
