Jamal Murray scored 40 points, and the Denver Nuggets completed a stunning comeback in the Western Conference semi-finals with a 104-89 victory over the Los Angeles Clippers in Game 7 last night at the NBA bubble near Orlando.

The third-seeded Nuggets became the first NBA team to rally from 3-1 deficits twice in the same postseason, having defeated the Utah Jazz in the first round. Denver will meet the top-seeded Los Angeles Lakers in Western Conference finals, which begin on Friday.

"We just believe in each other," Murray said on ESPN afterward.

Murray, who also had five assists, connected on 15 of 26 shots, including 6 of 13 from 3-point range. Nikola Jokic had 16 points, 22 rebounds and 13 assists for Denver, and Jerami Grant and Gary Harris contributed 14 points apiece.

"This is just a special group," Jokic told ESPN.

Earlier, Jimmy Butler fought through traffic for the game-winning bucket with 12 seconds remaining in overtime as the Miami Heat edged the Boston Celtics 117-114 in Game 1 of the Eastern Conference finals.

Butler drew a foul on the play and made the free throw to put the Heat up 116-114. Bam Adebayo blocked Jayson Tatum's attempt to tie the score with 3.7seconds remaining, and after Adebayo made 1 of 2 at the free throw line, Tatum missed on a 3-point attempt as time expired to seal the result.

"He made a great play," Tatum said of Adebayo's block. "That's all it is. He made a good play, can't do anything about it."

Butler added, "That sealed the game for us. ... (Adebayo is) a huge part to why we're winning -- I've been saying it all year long, and I'll repeat it again."

Goran Dragic led the Heat with 29 points with seven rebounds, Jae Crowder added 22 and sunk five 3-pointers, and Butler scored 20 for the Heat, who won or the ninth time in 10 playoff games.

Adebayo had 18 points and nine assists, and Tyler Herro fell an assist shy of a triple-double (12 points, 11 rebounds, 9 assists).

Tatum had a game-high 30 points with 14 rebounds, Marcus Smart scored 26 and Kemba Walker had 19 for the Celtics. Walker put Boston up 114-113 on a step-back bucket with 23.6 seconds left in overtime

Game 2 of the best-of-seven series will take place on Thursday.

"It was a great win. We're up 1-0, but we got three more to get," Adebayosaid.

The Celtics had led by 14 early in the fourth quarter before the Heat got within 101-98 on a Herro 3-pointer with 3:17 remaining.
