Glenn undergoes knee surgery

Cowboys wide receiver Terry Glenn will try to play again this season. The veteran underwent right knee surgery on Thursday and opted against the microfracture operation, the Dallas Morning News reports. Glenn had a less serious procedure on his cartilage. "There's no timetable as to when, but with this procedure, they feel like he has a chance to come back and make a run at playing this season," team spokesman Rich Dalrymple says. Patrick Crayton is starting in Glenn's place. Previous reports said this operation would cause Glenn to miss another three or four weeks, but we imagine the team will update that timetable in the next day or two. Plus, we are talking about Glenn here, and three weeks can easily turn into much longer, especially considering that microfracture was an option.
