Boston Celtics  starting center Kendrick Perkins  will miss at least the next three games with a reoccuring left shoulder injury. He did not play in Sunday’s game against the Toronto Raptors , is inactive for tonight’s game against the Raptors, and is not expected to play in Wednesday and Saturday’s games against the New Jersey Nets .
“Once it goes out we basically are going to have to be just lucky,” Doc Rivers  said before the game.
Rivers sited Perkins’ injury for his lack of productivity on the glass. He said Perk has not been able to effectively rebound since he hurt his shoulder on Christmas Day against the Los Angeles Lakers . Perkins is averaging 8.8 points and 8.1 rebounds in 27 games this season.
