Kevin Youkilis (back) said Sunday that he has not ruled out returning to the Yankees this season. Youkilis underwent surgery in mid-June to repair a herniated disc. "The thing about the back is, there's no timetables - the surgery, it's different for everybody in different ways," the veteran third baseman said. "We hope we can play this year but you have to go through all the progressions first and that's what I'm doing."
