FOXBOROUGH, Mass. -- Patriots tight end Rob Gronkowski has undergone surgery on his broken left arm, a person with knowledge of the operation tells The Associated Press.
The person spoke on condition of anonymity because the team has not announced the surgery.
Gronkowski suffered the season-ending injury Sunday when he caught a pass from Tom Brady in the first quarter and landed out of bounds on the arm for an incompletion in New England's 41-28 playoff win over the Houston Texans.
Gronkowski had previously had surgery on the same arm after breaking his forearm on 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.
The Patriots (13-4) host the Baltimore Ravens (12-6) in the AFC championship game Sunday.
