An upset was in the air at The Sports Arena in San Diego, California on the 31st March.

With Ali entering this bout as a 5 to 1 favourite, Norton surprised most, including Ali with his efficiency at landing hard punches throughout. At some stage, one of these powerful blows broke Ali's jaw. "The Greatest" as Ali called himself, managed to hear the final bell despite the severe pain he had to endure.

Norton won by split decision to hand Ali only his second career defeat.
