BOSTON (CBSNewYork/AP) — J.R. Smith was ejected from Cleveland’s playoff game on Sunday after swinging his arm back and knocking Boston’s Jae Crowder to the floor early in the second half.

Crowder remained there for a few minutes before leaving for the locker room. The Celtics said he had a sprained left knee and would not return.

Smith was charged with a flagrant foul. Isaiah Thomas made the two free throws, then Avery Bradley hit a basket when the Celtics put the ball in play.

The Cavs won, 101-93, to sweet the first-round series.
