Celtics principal owner Wyc Grousbeck says the team isn't going to make a move in the wake of Paul Pierce's recent knee injury.

Pierce is going to miss two weeks of action.

"We've got a roster of 15 players. We're not going to be cutting anybody," the owner told the Boston Globe. "We don't have any open roster spots. We've got guys to practice. I'm glad to see Tony Allen's playing very well and we'll have to have people like Tony to step it up."
