Cardinals quarterback Kurt Warner underwent arthroscopic hip surgery on Tuesday, according to the team. The operation was to repair a torn labrum and "clean up some loose fragments" and was preformed by the same doctor that worked on Yankees third baseman Alex Rodriguez earlier this month. "Everything went well and I'm feeling great," Warner said in a statement released by the team Wednesday. "I began rehab on a stationary bike just a few hours after surgery and then a couple of more times today."
