Celebrities and athletes gathered in Phoenix Saturday to honor Muhammad Ali and raise money for the Muhammad Ali Parkinson Center at Barrow Neurological Institute at Celebrity Fight Night. Arizona Cardinals coach Bruce Arians, former quarterback Kurt Warner and current QB Carson Palmer all attended, and Palmer even got on the mic to belt out Walking in Memphis.
