Orioles outfielder Jay Gibbons will have surgery Tuesday to repair a torn labrum in his left shoulder, prematurely ending one of the most disappointing seasons of his professional career. Gibbons decided to have the surgery Monday after an arthrogram confirmed a "fairly substantial" tear in the front of his shoulder that Gibbons thinks occurred when he dived for a ball in the outfield in late May. Gibbons will likely remain active with the club through the homestand that ends tomorrow before going on the disabled list for the rest of the season. The surgery will be performed by Cincinnati Reds team physician Timothy Kremchek, who also did the ligament-transplant surgery on Brian Roberts' left elbow in September 2005.
