Veteran pitcher Bartolo Colon's return to the White Sox' rotation has hit a speed bump.
General manager Ken Williams revealed Wednesday that Colon underwent surgery in the fall to remove bone chips from his right elbow, a procedure that will keep the big right-hander off the mound when the Sox open spring training Feb. 15 in Glendale, Ariz.
''We'll bring him along in the second half of spring training,'' Williams said.
