Former heavyweight champion Ken Norton, who beat Muhammad Ali and then lost a controversial decision to him in Yankee Stadium, died today in Las Vegas at age 70. Norton had been in poor health for the last several years after suffering a series of strokes, a friend said. Norton broke Ali's jaw in their first bout, beating him by split decision in 1973 in a non-title fight in San Diego. They fought six months later, and Ali narrowly won a split decision. They met for a third time on Sept. 28, 1976, at Yankee Stadium, and Ali narrowly won to keep his heavyweight title.
Norton would come back the next year to win a heavyweight title eliminator and was declared champion by the World Boxing Council. But on June 9, 1978, he lost a bruising 15-round fight to Larry Holmes in what many regard as one of boxing's epic heavyweight bouts and would never be champion again. Norton finished with a record of 42-7-1 and 33 knockouts. He would later embark on an acting career, appearing in several movies, and was a commentator at fights. (Read more obituary stories.)
