The bench of the Boston Celtics relies on a select few guys, and one of them is going to be unavailable for a while. The Boston Globe (Marc J. Spears) reports (via blog):

Celtics president Danny Ainge said that guard Tony Allen is slated to have left thumb surgery tomorrow and he is hopeful he will return to action by the playoffs. The injury-plagued Allen suffered the injury on Feb. 8 versus San Antonio and has already missed 15 games this season to ankle and thumb injuries.

Allen this season is 7th on the team in scoring and in 19.1 minutes per game averages 7.8 points and 2.1 rebounds per game. He’s shooting well from two-point range but his three-point shot has been virtually nonexistent.
