Wilford "Whizzer" White, the father of former Dallas Cowboys quarterback Danny White and a member of the Arizona State hall of fame, has died at the age of 84.

White's daughter-in-law, Michelle White, says the former Sun Devils running back died Thursday after falling unconscious while awaiting a doctor's appointment.

She says he died while on an ambulance headed to a Phoenix-area hospital possibly of a heart attack, but family members are still awaiting tests.

White was an ASU running back from 1947 to 1950 and finished his career as the school's all-time leading rusher with 3,173 yards.

Steve Patterson, vice president for university athletics, called White "one of our all-time great athletes."

White's son, Danny, was a Sun Devils quarterback before going on to play 13 seasons for Dallas.
