The Celtics had already trimmed their roster to the league limit of 15 players, but their opening night roster is now official as they placed three players on the inactive list: Kendrick Perkins, Avery Bradley and Semih Erden. The Celtics will have to play the first 10 games of the NBA with just 11 active players because of Delonte West’s suspension. League rules dictate that suspended players must be carried on the active roster.

The inactive list is not like injury lists in other sports. Players don’t actually have to be injured to be on it and there is no mandatory amount of time that a player has to stay on it once he is deemed inactive. It can also change from game to game. There were no surprises for the Celtics. Perkins and Bradley are rehabbing injuries, while Erden is dealing with a shoulder injury.

The Heat had a minor surprise as they placed Mario Chalmers on the injured list along with Mike Miller, who is out until January with hand injury, and rookie Dexter Pittman.
