Ray Allen to sit out again

The Boston Celtics' bench will be thin Tuesday night against the New York Knicks as both Ray Allen (ankle) and Mickael Pietrus (knee) will miss the game.

Allen appeared set to return after joining the team in New York and going through a morning shootaround, but the ankle flared up after the session, according to coach Doc Rivers. Pietrus, who had offseason knee surgery, experienced some swelling after the Celtics endured a back-to-back-to-back this past weekend.

Allen has now missed 11 of the team's last 16 games. Pietrus missed 10 games while recovering from a concussion before returning for the last four games.
