Hanrahan has Tommy John surgery

ST. PETERSBURG, Fla. -- Boston Red Sox reliever Joel Hanrahan underwent Tommy John elbow reconstruction surgery Thursday, the team announced Thursday.

Dr. James Andrews, who performed the surgery, repaired the ulnar collateral ligament in Hanrahan's elbow as well as the torn flexor muscle with which he was originally diagnosed. Andrews also removed bone spurs from the elbow, according to a tweet from Mike Dillon of Reynolds Sports Management, one of Hanrahan's agents.

Typically, a pitcher is out from 12 to 16 months after undergoing Tommy John surgery.
