The Boston Globe (Marc Spears) reports: Celtics forward/center Scot Pollard said before tonight’s game against the Detroit Pistons that he will be out for the rest of the season with a torn tendon in his left ankle. Pollard has had a lingering left ankle injury since October that hasn’t healed. The original injury revealed a slight tear that became a lot worse as shown on an MRI today, Pollard said.
