The Dallas Mavericks downgraded Luka Doncic to questionable for Game 2 of the NBA Finals against the Boston Celtics on Sunday.

With the Mavericks in danger of dropping the first two games in Boston, the injury designation from probable was made about 6 1/2 hours prior to tip-off.

He was also diagnosed with new ailment on the report, with a thoracic contusion being added to prior injuries of a right knee sprain and left ankle soreness.

Video posted of him from Saturday's practise showed the five-time All-Star holding his chest while appearing to be in some pain.

Doncic has routinely been listed on the injury report throughout the play-offs, but has yet to miss a game in the post-season.

Despite dealing with multiple injuries, he's still averaging 28.8 points, 9.7 rebounds and 8.4 assists in the play-offs.

In Dallas' 107-89 loss to Boston in Thursday's Game 1, he finished with 30 points, 10 rebounds and one assist.

Jaylen Brown hailed Kristaps Porzingis after the Boston Celtics power forward returned from injury with a "monster game" against the Dallas Mavericks.

Porzingis, who has been absent for five weeks with a calf strain, played a starring role from the bench against his former side, as the Celtics drew first blood in the NBA Finals with a 107-89 win in Game 1.

Having not played since Game 4 in the first round against the Miami Heat, the Latvian marked his return with 20 points, six rebounds and three blocks at TD Garden.

And Brown, who top-scored for the Celtics with 22 points, paid tribute to his team-mate.

"Kristaps had a monster game for us," he said. "Just his presence shooting the ball and then him being able to attack those switches and mismatches, he made them pay every time, and that's what we need going forward in the series."

Porzingis was understandably thrilled to make up for lost time with his inspired display for top seeds Boston, who are targeting a record-breaking 18th NBA title this year.

"The adrenaline was just pumping through my veins," he said. "Obviously, it wasn't ideal that I was out for such a long time.

"But, I did everything I could to prepare mentally for this moment coming back, and it paid off, and we got the job done tonight and had a good game, and happy about the result.

"Tonight was an affirmation to myself that I'm pretty good, you know? Maybe I'm not perfect, but I'm pretty good and I can play like this and I can definitely add to this team."

P.J. Washington urged the Dallas Mavericks to "stay connected and together" following defeat to the Boston Celtics in their NBA Finals opener. 

The Mavs' first championship series since they were crowned champions in 2011 began with a 107-89 loss against the top seeds of this postseason at TD Garden.

It was Dallas' lowest scoring total during the playoffs, while their tally of just nine assists was the fewest in any match this term as they struggled against a strong Boston defense.

"We just have to stay connected [and] stay together," said P.J. Washington. "We are a great team. They are a great team at the end of the day. We're all right. It's only one game. We'll be better for Game 2."

"The ball has got to move a little bit more," added Kyrie Irving, whose 31.6 per cent shooting from the floor was his lowest in 14 career Finals games.

"That starts with me just being able to push the pace, get us some easy opportunities, and just adjust to what they are throwing at us.

"It's a fun series. It was fun going into the game. It's still going to be fun. But there's going to be a level of chess that still has to be played."

Mavs coach Jason Kidd also issued a rallying cry to his players, who he insisted must not be held back by the occasion.

"Give the Celtics credit," he said. "They did a great job defending, making it tough on us.

"I think this is the best team in the NBA, and they are good for a reason. They play their style of basketball at a high rate. Nerves or not being in this situation, we can't use that as an excuse. It's just basketball."

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.

Kyrie Irving is the "most gifted player the NBA has ever seen" and holds the key to the Dallas Mavericks' chances of victory in the NBA Finals, according to former team-mate LeBron James.

James and Irving played together with the Cleveland Cavaliers from 2014 to 2017, making the NBA Finals in each of those seasons and triumphing in 2015-16.

Irving then enjoyed stints with the Boston Celtics and Brooklyn Nets before joining Dallas last February. 

He has been in great form during the offseason, averaging 22.8 points and 5.2 assists as well as shooting 48.5 per cent from the field to help put Dallas in contention for their second NBA championship. 

Speaking on an episode of his 'Mind the Game' podcast, James said of Irving: "I'm so happy and so proud to watch him continue his growth. 

"I'm so f****** mad at the same time that I'm not his running mate any more.

"I would call Kyrie 'the wizard' all the time. There was nothing on a basketball floor that Kyrie couldn't do."

James highlighted Irving's performance in Game 1 of the Western Conference finals, when he scored 24 of his 30 points in the first half against the Minnesota Timberwolves, as the standout moment of this postseason.

While Boston may be favourites for the NBA Finals, which tip off on Thursday at TD Garden, James says Irving's ability gives Dallas a chance.

"That was like, 'oh s***, Dallas may be able to not only win the Western Conference finals, they might be able to win the whole thing'," James said of Irving's Game 1 display.

"Because of that wild card. He's the most gifted player the NBA has ever seen."

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."

Luka Doncic was in "magic mode" after his starring role helped the Dallas Mavericks to their first NBA Finals since 2011, coach Jason Kidd said.

The Mavs and the Boston Celtics will battle it out for this season's NBA championship after Dallas wrapped up a 4-1 Western Conference finals series victory over the Minnesota Timberwolves.

A 124-103 win did the trick at Target Center on Thursday, with Doncic and Kyrie Irving leading the way for the Mavs with 36 points apiece.

Doncic was quick out of the blocks, scoring 20 of his points during the first half on the way to notching up his highest-scoring contributions of the postseason, with his performances earning the Western Conference finals MVP award.

"It was Luka magic mode," Kidd said. "He set the tone, and then he made it easier for everyone else. Everybody else stepped up."

"You're just watching a special performance take place," Irving added. "When Luka starts off a game like that, we're a tough team to beat."

Indeed, they are. The Mavs are 7-2 on the road during the playoffs - winning the last five - matching the franchise record for such victories during a single postseason, set in their title-winning campaign of 2010-11.

A EuroBasket champion with Slovenia and EuroLeague winner during his final season with Real Madrid, Doncic is now gearing up for his first crack at an NBA title, with the Finals series commencing on June 6.

And he insists his team-mates cannot afford to rest on their laurels.

"It was a very hard road, very hard," Doncic said. "But we're not done. We have four more [victories to achieve]."

Luka Dončić scored 20 of his 36 points in the first quarter and Kyrie Irving also scored 36 as the Dallas Mavericks booked a trip to the NBA Finals with a 124-103 rout of the Minnesota Timberwolves on Thursday night.

Dallas was never threatened in Game 5 as it built a 29-point halftime lead on 61 percent shooting and led by as many as 36 points in the third quarter.

The Mavericks will have a full week to rest before the NBA Finals begin in Boston on June 6 for the franchise’s first appearance since winning the title in 2011. The Celtics have been off since finishing a sweep of Indiana on Monday.

Irving improved to 15-1 in his career in closeout games in the playoffs.

Anthony Edwards scored 28 points and Karl-Anthony Towns had 28 with 12 rebounds for the Wolves, who were unable to build on Tuesday’s Game 4 win in Dallas.

Doncic hit his first four shots and drained a 32-footer later in the first quarter. The Mavs closed on a 17-1 spurt, a run they pushed to 28-5 over a nine-minute stretch.

It was Doncic’s second 20-point quarter in his postseason career, following a 21-point fourth quarter in the Western Conference finals loss to Golden State in 2022.

Dallas got backup center Dereck Lively II back from a sprained neck that sidelined him the previous game. He had nine points and eight rebounds and Daniel Gafford added 11 points and nine boards.

Anthony Edwards credited Karl-Anthony Towns after he halted his slump to keep the Minnesota Timberwolves alive in their Western Conference finals series against the Dallas Mavericks.

Towns scored 20 of his 25 points in the second half as Minnesota held off a late Dallas rally for a 105-100 road win, forcing a Game 5 in Minneapolis on Thursday.

That came after a difficult start to the series for the four-time All-Star, with coach Chris Finch saying it was "hard to watch" his struggles in Game 3.

Towns shot just 27.8 per cent in the series' first three games, but was 9 of 13 from the floor and made 4 of 5 from 3-point range on Tuesday.

Edwards, who narrowly missed out on a triple-double with 29 points, 10 rebounds and nine assists, said Towns was the primary reason the Timberwolves retained hope of an NBA Finals berth. 

"Everything came together for him; he was super confident," Edwards said of Towns. 

"He played exceptionally well, and he came through big-time. He was the reason we won tonight."

Finch echoed Edwards' praise, saying: "KAT's a great player. His struggles were not going to last forever. He got himself going. 

"Even when he got deep in foul trouble, we left him out there, just let him roll, and he played smart, played under control, rebounded really well for us, executed defensively. We're really proud of him. Tonight was a great step for him."

While it was Towns' efforts that gave Minnesota a lead to defend, it was Edwards who made certain of the victory with a mid-range jumper after the Mavs pulled within three points just over a minute before the buzzer. 

Towns, who fouled out with one minute and 38 seconds on the clock, said of his team-mate's game-sealing shot: "I was on the bench and had a front-row seat. I feel like he was visualising that make and he got to exactly the spot he wanted to.

"I'm honoured to be playing with my brother here, seeing him every day put the work in, and I knew when he got to that shot it was a high likelihood he was going to make that."

Anthony Edwards just missed a triple-double, Karl-Anthony Towns scored 20 of his 25 points in the second half and the Minnesota Timberwolves held on to beat the Dallas Mavericks 105-100 on Tuesday to avoid being swept in the Western Conference finals.

Facing a 3-0 series deficit on the road, the Wolves conjured their best defensive game of the series to force a Game 5 on Thursday night in Minneapolis.

Dallas' Luka Doncic finished with 28 points, 15 rebounds and 10 assists but was held to 7-for-21 shooting. Kyrie Irving shot 6 of 18 from the field to finish with 16 points.

"That game's on me. Just didn't give enough energy," Doncic told reporters after the game. "They won one game. We've just got to focus on the next one."

Towns, who shot 27.8 per cent in the series' first three games, was 9 of 13 from the floor and made 4 of 5 from 3-point range. Despite his redemptive performance on offense, Towns fouled out with 1:38 remaining after falling for a Doncic pump fake at the 3-point line.

Edwards was assertive from the opening tip, scoring 14 points in the first quarter, and finished with 29 points, 10 rebounds and nine assists.

The Mavs pulled to within 100-97 with just over a minute remaining before Edwards hit a mid-range jumper to extend the Minnesota lead. On Dallas' following possession, Kyle Anderson stole the ball from Irving to extinguish the threat.

The Mavericks played without standout rookie center Dereck Lively II due to a neck sprain after taking a rough fall in Game 3.

No team has ever come back from a 3-0 series lead, but the Wolves will hope to keep the pressure on Dallas in Game 5.

No team has ever come back from a 3-0 series lead, but the Wolves will hope to keep the pressure on Dallas in Game 5.

Luka Doncic says Kyrie Irving was "born for the clutch situations" as the Dallas Mavericks produced another late show to deny the Minnesota Timberwolves.

The Mavs, who overcame a late two-point deficit, prevailed 116-107 in Game 3 of the Western Conference finals series, becoming the first NBA side in history to take a 3-0 series lead despite trailing in the final five minutes of the fourth quarter in each game.

Dallas had the second-best clutch record (23-9) and best clutch offence (127.1 points per 100 possessions) during the regular season, and have continued that momentum into the playoffs.

Indeed, they also came from behind late on in Game 6 of their conference semi-final series victory over the Oklahoma City Thunder.

Irving scored 14 points in the fourth quarter in Game 3, and now has 31 such points this series; the most by any player in this year's conference finals.

"Unbelievable. That's why some people call him Mr Fourth Quarter, right?" Doncic said of his team-mate. "Just amazing. He's born for these situations. He's born for the clutch situations, so we just get the ball to him."

"Down the stretch, that's where we make our money," Irving added. "I think we have that poise now, and we're just showcasing our skill sets out there that a lot of teams have to guard, the depth that we have. A lot of teams have to guard each one of us, and you got to pick your poison."

Irving and Doncic scored 33 points apiece to become the first starting backcourt to each register at least 30 points in three playoff games over the past 50 seasons.

"I feel like we're both born for this if you ask me, but it's just basketball. You've got to give the game what it needs at times," said Irving, who called for focus in his franchise's quest for a second NBA title.

"It doesn't mean anything if we don't win a ring together. Right now, I want to show a lot of respect to the guys that have come before us and have actually done it. And our time will come."

Luka Doncic loves the big stage, and that's what makes him "special" to Dallas Mavericks head coach Jason Kidd.

Doncic again displayed his ability to perform in the biggest moments on Friday as he drained a 3-pointer over four-time Defensive Player of the Year Rudy Gobert to lead the Mavericks to a 109-108 victory over the Minnesota Timberwolves, one that leaves them 2-0 up in their Western Conference final.

The Mavericks came back from an 18-point deficit to tighten their grip on the series, with Doncic leading the way. The five-time All-Star ended the game with 32 points, 13 assists and 10 rebounds, becoming just the fourth player in NBA history to manage four triple-doubles across a five-game postseason span.

Kidd hailed Doncic's game-winning impact, saying there was no other option but to try and get him the ball when deciding what play to run during the timeout with 13 seconds remaining

"As you've seen, he loves that stage," Kidd told reporters. "He doesn't run from it. He made a big shot. Luka is special. He loves those type of moments.

"The play was to get Luka the ball and let Luka do what he does in those moments."

Doncic believes the comeback, the Mavericks' third-biggest in their postseason history, was down to his team's mindset as he ruthlessly snatched the game away from the Timberwolves.

"Like I always say, stay together, positive energy," Doncic explained. "We believed until the end.

"I just saw some space and decided to shoot a 3. Get to my spot, step back. That's it."
