Joe Frazier, a tough, underrated heavyweight boxer from Philadelphia and one of the sport’s fiercest competitors who spent a lifetime playing second fiddle to his nemesis, Muhammad Ali, died Monday night from liver cancer. He was 67. Frazier’s death was announced in a statement by his family, who asked to be able to grieve privately. “Smokin’ Joe” Frazier was the first fighter to defeat Ali during their first fight, the so-called “Fight of the Century” in Madison Square Garden on March 8, 1971, one of the most epic ring battles of all time.
