PHILADELPHIA -- Rockies shortstop Troy Tulowitzki underwent successful surgery on Thursday to remove scar tissue that was built up over a nerve in his left groin area. According to manager Jim Tracy, nothing unexpected was found during the operation, which was performed by Dr. William Meyers in Philadelphia.There is no set timetable for Tulowitzki's return to the field, but he is likely to be sidelined at least six more weeks. Rockies general manager Dan O'Dowd told the Denver Post on Wednesday that Tulowitzki would likely miss eight weeks. The two-time All-Star was hitting .287 with eight home runs and 27 RBIs in 47 games, but he has not played since May 30. His presence is missed on the Rockies, who are 25-42 and lost 12 of 13 games entering Thursday's series finale with the Phillies. Tulowitzki will spend the night in Philadelphia, and walk a mile with Rockies head athletic trainer Keith Dugger on Friday. It will likely be three weeks of exercises before Tulowitzki progresses into baseball activities, Tracy said. "We know that he has peace of mind in knowing that what it was that he was dealing with is now fixed, and the time frame is not longer than initially anticipated after doing the tests and looking at MRIs and things like that," Tracy said. "We're very encouraged in relation to the news that we got."
