Muhammad Ali punches Ken Norton during their 1976 fight at Yankee Stadium. The two fought twice in 1973, splitting the fights, before the ‘76 rubber match. Ali slugged his way to a unanimous decision in 15 rounds. Norton’s own coaches believed their fighter had a comfortable lead heading into the 15th and advised Norton to stay away from Ali, which he did, possibly giving the fight away. After the bout, even Ali admitted he thought he had been beaten. (Jerry Cooke/SI)
