OAKLAND -- Carl Crawford had surgery to repair a subluxation of his right middle finger tendon on Thursday in Phoenix.

According to Rays spokesman Chris Costello, the surgery "went well."

There is no definitive word on a timetable for Crawford's return, but it has been speculated that the best-case scenario would be the final week of the regular season.

Crawford, a two-time American League All-Star, said he heard something pop when he checked his swing on a 3-1 pitch from J.J. Putz in the 10th inning of Saturday night's game in Seattle. The injury was located at the joint connecting the base of his middle finger to his right hand.
