Boxing legend Roberto Duran, a four-time champion in four different weight classes, is receiving medical care for a heart problem, his family confirmed in a statement Friday. 

The family of 72-year-old announced Duran’s condition in a statement, adding that he is receiving treatment after suffering "a health complication due to an atrioventricular blockade."

Duran was world lightweight, welterweight, junior-middleweight, and middleweight champion, who saw immediate success in his professional career, winning his first 32 matches. He won his first title in 1972 and successfully defended it 12 times. 

Duran won the welterweight division in 1980 against Sugar Ray Leonard, but lost in a subsequent match just months later, where he infamously said, "No mas" late in the eighth round.
