He was the second man to beat Muhammad Ali, breaking Ali's jaw and sending him to the hospital in their 1973 heavyweight fight. Ken Norton frustrated Ali three times in all, including their final bout at Yankee Stadium where he was sure he had beaten him once again. Norton, who died Wednesday at the age of 70, lost that fight for the heavyweight title. But he was forever linked to Ali for the 39 rounds they fought over three fights, with very little separating one man from the other in the ring.

"Kenny was a good, good fighter. He beat a lot of guys," said Ed Schuyler Jr., who covered many of Norton's fights for The Associated Press. "He gave Ali fits because Ali let him fight coming forward instead of making him back up." Norton is the only heavyweight champion never to win the title in the ring, and boxing fans still talk about the bruising battle he waged with Larry Holmes for the title in 1978. But it was his first fight with Ali that made the former Marine a big name and the two fights that followed that were his real legacy.
