BOSTON -- LeBron James has never participated in an NBA Slam Dunk Contest, and every once and a while he throws down a dunk that makes fans wish he did take part in the All-Star Weekend event.

In Tuesday's game against the Boston Celtics at TD Garden he did just that.

The Cleveland Cavaliers forward capped a 12-0 run to begin the third quarter with a double pump reverse jam, drawing applause from the Cavs fans at TD Garden.
