Preston Wilson is going to have arthoscopic knee surgery to repair torn cartilage in his knee. He has been put on the 15 day DL, retroactive to April 13th.
This line is from an ESPN article, and it is very telling (scary, for fantasy owners):Wilson, who did not start for the third straight game Wednesday night, has torn cartilage in his left knee. While he was hopeful of returning to play this season, there was no timetable on his recovery.
