The Texans' starting nose tackle--though he could be anyone's starting nose tackle from this point forward, as he's due to become an unrestricted free agent--had back surgery in late January. If you weren't already aware of it, Shaun Cody had back surgery out in California a week and a half ago: Cody was bothered by a back injury he suffered in preseason. Dr. Robert Watkins performed a “successful microscopic lumbar discectomy surgery for a lumbar disc herniation” at Marina Del Rey Hospital, according to a release put out by the doctor. The surgery was performed on Jan. 29. Cody, whose contract expires in March, played in 13 games last season, including 12 starts.
