ネバダ州アスレチック・コミッション
It was around this time that Ali started struggling with vocal stutters and trembling hands. The Nevada Athletic Commission (NAC) ordered that he undergo a complete physical in Las Vegas before being allowed to fight again. Ali chose instead to check into the Mayo Clinic, who declared him fit to fight. Their opinion was accepted by the NAC on July 31, 1980, paving the way for Ali's return to the ring.
