Varitek had arthroscopic knee surgery Thursday and was expected to begin rehabilitation immediately, though there was no timetable given for his return. The Boston Red Sox catcher left Monday's game after the third inning with a twisted left knee. He'd been hit on the knee Saturday when he blocked home plate and appeared to be favoring it while rounding second base Monday.
