Boston Red Sox right-hander Joel Hanrahan was examined Friday morning by Dr. James Andrews and is mulling season-ending surgery.
Hanrahan has a flexor pronator strain in his right elbow.
"What's been pretty conclusive or in agreement with other examinations is that he's got some damage to the flexor muscle tendon, so he's en route to Boston as we speak," John Farrell said Friday. "I know that he'll revisit with the training staff and medical staff here.
"At some point, there's got to be a decision as to which course he's going to take to rectify the situation."
Tests have indicated the ulnar collateral ligament in Hanrahan's elbow is not involved in the injury, but Farrell left open the possibility that further examination could result in electing to repair the ligament as well, requiring Tommy John surgery.
"Everything that shows right now is it's the flexor tendon," Farrell said. "If, in fact, that course is chosen to surgically repair the tendon, they would have the opportunity to fully examine the ligament at that time."
