Former heavyweight boxer Ken Norton Sr. dies at 70
SEP 18, 2013 4:28p ET
Norton broke Ali's jaw in their initial fight, then lost at the Inglewood Forum in the rematch. Ali defeated Norton again in a decision at Yankee Stadium in New York in 1976.
In 1978, Norton won the World Boxing Council heavyweight championship when Leon Spinks chose not to fight him. He lost the title to Larry Holmes that June.
Norton finished with a record of 42-7-1 and 33 knockouts. He later went on to an acting career.
One of his sons, Ken Norton Jr., was a star linebacker at UCLA who played for the Dallas Cowboys in the NFL and now coaches for the Seattle Seahawks.
