Patriots tight end Rob Gronkowski underwent surgery on his broken left arm, a person with knowledge of the operation told The Associated Press. Gronkowski suffered the season-ending injury Sunday when he caught a pass fin the first quarter and landed out of bounds for an incompletion in New England‘s 41-28 playoff win over the Houston Texans. The person spoke on condition of anonymity because the team has not announced the surgery. Gronkowski had earlier surgery after breaking his left forearm Nov. 18 in a 59-24 win over the Indianapolis Colts. He missed five games and returned for the season finale, a 28-0 victory over the Miami Dolphins. Source: Associated Press
