The engine failure QRH was accomplished, an emergency declared and we made an immediate return and landing in phoenix. Approach, landing and rollout were normal. An overweight landing at approximately 134000 pounds was made. Flight crew was debriefed and inquiries made as to whether any passenger required medical assistance. None was needed. We were unsure of what caused this failure. The engine has been replaced, and the damaged one will be torn down to determine the cause. Callback conversation with reporter revealed the following information: in talking to both rptrs, neither knows what, in the engine, failed. The crew inspected the engine after landing.
