According to a source, Carl Crawford will undergo Tommy John surgery on Tuesday to repair the torn ulnar collateral ligament in his left elbow.

However, Red Sox general manager Ben Cherington denied that a decision on Crawford having surgery had been made.

The Red Sox said early Sunday that the team planned to meet with Crawford and members of the medical staff on Monday to make a decision about the possible surgery.

"We want to make a focused decision tomorrow on what's best for Carl," Cherington said. "Listen to him, look at all the available information and figure out if this is something that needs to be fixed (immediately) or if he can continue to play with it."
