The Celtics beat the Cavaliers 107–94 in Game 2 of the Eastern Conference finals, but the big moment of the fourth quarter came from Clevaland's J.R. Smith.

Smith pushed Al Horford while he was up in the air as he was going for a dunk. Marcus Smart was not happy about the move from Smith and came over to confront him.
