Former boxing champion Ken Norton, considered one of the greatest heavyweights of his era, died on Wednesday at an Arizona care facility, the LA Times reported. He was 70.

The fighter was best known for beating Muhammad Ali in 1973, breaking the Hall of Famer’s jaw in the process.

Norton, who suffered a stroke last year, ended his brilliant career with a record of 42 wins, seven losses, one draw and 33 knockouts.

He fought in the 1970s era of magnificent heavyweights -- a group that also included Ali, George Foreman, Joe Frazier, Leon Spinks and Jimmy Young.

“They called us handsome. Muhammad they called pretty. But the fairest of them all Ken Norton,” Foreman wrote on his Twitter page on Wednesday. “What a loss to all of us.”

Other tributes also quickly poured in for Norton, who was once given the title of the “Father of the Year” by the Los Angeles Times in 1977. “My heart has been heavy since hearing the news earlier today,” boxer Larry Holmes wrote on Twitter. “He was a good man. #RIP #KenNorton.”

Norton was born in Jacksonville, Illinois, and was an award-winning athlete in American football and track and field at Jacksonville High School.

He started boxing during his four year-stint in the United States Marine Corps, which he joined in 1963.

In March 1973, Norton shocked the boxing world by winning a split decision over Ali at the San Diego Sports Arena.

He would go on to fight Ali twice more, losing both times. He lost a split decision to Ali later in 1973 and by a unanimous decision in 1976 at Yankee Stadium. In 1974, Norton fought and lost to Foreman in Venezuela for the World Boxing Council and World Boxing Association heavyweight titles. The fight was stopped in the second round after Foreman knocked him down three times.

Norton, who was nicknamed “The Black Hercules”, also fought Holmes, losing his title late in his career to the up-and-coming heavyweight in 1978. It was the first defence of the WBC title for Norton, who fought in the era where championship fights lasted 15 rounds.
