The news came from his son , Seahawk's LB coach Ken Norton Jr, who was visibly upset.
Ken Norton Sr was the only heavy weight champion to never win the belt in the ring (AP).
His epic battles with both Muhammad Ali and Larry Holmes brought the former marine to the lime light. Norton broke Ali's jaw in there first fight. He has been battling numerous strokes over the last several years and his health had been in major decline the last two years.
I hope Ken knows that the 12th man is there for him in this trying time, our thoughts go out to him.
