NBA PLAYOFFS: Celtics rally past Heat to prevent East finals sweep

Jayson Tatum collected 33 points and 11 rebounds as the visiting Boston Celtics staved off elimination with a 116-99 victory over the Miami Heat on Tuesday in Game 4 of the Eastern Conference finals.

Tatum made 14 of 22 shots from the floor -- including 4 of 8 from 3-point range. He also had seven assists for the second-seeded Celtics, who trail 3-1 in the best-of-seven series heading into Thursday's Game 5 in Boston.

Jaylen Brown scored 17 points and Derrick White added 16 to help the Celtics prevent Miami from becoming the second eighth-seeded team to advance to the NBA Finals. The 1998-99 New York Knicks accomplished the feat during a lockout-shortened season.
