According to the Globe, TA is having surgery to repair those damaged ligaments in his thumb:
Celtics president Danny Ainge said that guard Tony Allen is slated to have left thumb surgery tomorrow and he is hopeful he wil 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 is averaging 7.8 points, 2.1 rebounds and 1.21 steals in 19.1 minutes per game. The 6-foot-4, 213-pounder's injury opens the door for more playing time for guard Gabe Pruitt. "I hope he's ready for the playoffs," Ainge said.
Rumor has it, doctors will be replacing the thumb with Allen's big toe. The new digit should help cut down on Allen's turnovers. Maybe there's room for Starbury on this roster after all.
