R.I.P. Jimmy Young.

Former heavyweight boxer Jimmy Young, who beat George Foreman and fought Muhammad Ali and Ken Norton in the 1970s, has died. He was 56. Young died Sunday at Hahnemann University Hospital, a spokeswoman told The Associated Press on Tuesday. The Philadelphia Daily News reported that he died of heart disease after a six-day hospitalization. The 6-1, 210-pound Young compiled a 35-18-3 record with 12 knockouts during a career that spanned from 1969-90. Young lost a championship bout to Ali on April 30, 1976, although some boxing experts disputed the decision. He beat Foreman nearly a year later in a 12-round decision in San Juan, Puerto Rico, on March 17, 1977. But perhaps his toughest loss was a split decision to Norton on Nov. 5, 1977, in a WBC elimination bout in Las Vegas.
