His business representative, Leslie Wolff, told The Associated Press on Saturday that Frazier had liver cancer and that he had entered hospice care.
Known as Smokin’ Joe, Frazier stalked his opponents around the ring with a crouching, relentless attack — his head low and bobbing, his broad, powerful shoulders hunched — as he bore down on them with an onslaught of withering jabs and crushing body blows, setting them up for his devastating left hook.
It was an overpowering modus operandi that led to versions of the heavyweight crown from 1968 to 1973. Frazier won 32 fights in all, 27 by knockouts, losing four times — twice to Ali in furious bouts and twice to George Foreman. He also recorded one draw.
A slugger who weathered repeated blows to the head while he delivered punishment, Frazier proved a formidable figure. But his career was defined by his rivalry with Ali, who ridiculed him as a black man in the guise of a Great White Hope. Frazier detested him.
