The Miami Heat secured a play-off spot with a 129-121 win at the Boston Celtics that all but condemned the Celtics to the new play-in tournament.
Miami's 10th win in 13 games moved them into a tie for fifth in the Eastern Conference.
Meanwhile, the Los Angeles Lakers kept their play-off hopes alive with a 101-99 victory against the New York Knicks.
With LeBron James again absent through injury, Talen Horton-Tucker stepped up to hit the match-winning three-pointer.
The Lakers are hopeful James, who has missed their past five games with an ankle injury, can play against the Houston Rockets at home on Wednesday.
