Gary Sheffield will undergo surgery to repair his injured wrist on Tuesday, and the outfielder isn't expected to return to the Yankees until September.

Sheffield has been on the disabled list twice this season, both the result of injuries to his left wrist. Tuesday's surgery, which will be performed by hand specialist Dr. Charles Melone, will repair both the torn ligament and dislocated tendon in his wrist, which landed him on the DL on June 1.
