Bradley injured a shoulder in Game 2 against the Atlanta Hawks and re-injured it again in Boston's Game 3 win last night.
Bradley has fought a shoulder injury all season but it just hasn't worked out for him in the playoffs. He left last night's game in the third quarter and never returned after it was believed that he would return.
"It's really sore," Bradley told CSNNE.com after the game. "Every time I go to extend my arm, and it gets hit, it comes in and out."
"He's had that problem all year," said C's coach Doc Rivers. "Usually they're able to, like a leg, snap it back in. It wouldn't go back in."
As of now Bradley expects to be back for Game 4, but expect Celtics officials to hold him out.
