Shootaround: 15 participate for C's

WALTHAM, Mass. -- All 15 players participated during the Celtics' shootaround Saturday morning at HealthPoint, including Paul Pierce (sprained left knee), Avery Bradley (sore left shoulder), and Ray Allen (sore right ankle), according to team officials.

There have been no changes in the status of any players, meaning Pierce and Bradley are expected to play tonight, while Allen will be a game-time decision for Game 1 of an Eastern Conference semifinal series against the Philadelphia 76ers at TD Garden.

The hourlong set consisted of a brief film session followed by a walk-through of offensive and defensive sets.
