Texans nose tackle Shaun Cody was released from a Los Angeles hospital on Thursday after undergoing surgery on his spine. 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. Meanwhile, receiver DeVier Posey underwent surgery to repair a ruptured Achilles tendon he suffered in the playoff loss at New England. It’s too early in the rehab process to determine when he might be able to return.
