Celtics' Ray Allen leaves game

Boston Celtics guard Ray Allen left Sunday's game with the Washington Wizards after jamming his ankle midway through the second quarter.

Allen was chasing the Wizards' Nick Young around a baseline screen and went down in a heap. He attempted to walk it off but quickly signaled to coach Doc Rivers for a substitution before limping gingerly toward the bench.

Allen had seven points on 3-of-5 shooting before leaving with the injury.

The Celtics are already without point guard Rajon Rondo, who missed his second straight game with a right wrist injury.

Allen entered Sunday's contest averaging a team-best 15.5 points per game, along with 3.2 rebounds and 2.5 assists.
