Former heavyweight champ Norton dies at 70

Ken Norton Sr., a former heavyweight boxing champion, passed away Wednesday at an Arizona hospital, according to the Los Angeles Times. He was 70 years old.

Norton, who suffered a stroke last year, apparently died due to congestive heart failure.

Most remembered for his victory over Muhammad Ali in 1973, Norton finished his boxing career with a record of 42-7-1 and 33 knockouts.

One of his sons, Ken Norton Jr., played in the NFL as a linebacker for the Dallas Cowboys and San Francisco 49ers.
