TEMPE, Ariz. (AP) -- Arizona Cardinals quarterback Kurt Warner has undergone arthroscopic surgery on his left hip.

The team said that the operation to repair a torn labrum and "clean up some loose fragments" was performed Tuesday by Dr. Marc Philippon at the Steadman Hawkins Clinic in Vail, Colo.

Philippon, operated on Yankees slugger Alex Rodriguez's hip last week, said the surgery went well and Warner's range of motion with the hip immediately improved.
