The Miami Heat were again forced to stage a mammoth comeback in order to beat the Boston Celtics 106-101 as they took a 2-0 lead in the NBA Eastern Conference finals.

Just two days after overcoming a 14-point fourth-quarter deficit to win game one, the Heat again found themselves with their backs against the wall after giving up a 13-point lead in the first half.

Behind a slam-dunk exhibition from Bam Adebayo, Miami exploded in the third quarter to ultimately outscore the Celtics 59-41 down the stretch.

Adebayo and Goran Dragic combined for 46 points for Miami while Duncan Robinson was a constant threat from deep as he finished with six threes.

Meanwhile Kemba Walker had a much-improved performance for Boston, picking up 23 points and seven rebounds to go along with 21 each from Jayson Tatum and Jaylen Brown.

Los Angeles Lakers and Denver Nuggets will play Game One of the Western Conference finals at 2am Irish time on Saturday.
