Joe Frazier (1944–2011) was the undisputed heavyweight champion of the world and Muhammad Ali's greatest rival. His relentless pressure style and thunderous left hook made him one of the most feared fighters of his era.
Frazier's three bouts with Ali — including the brutal Thrilla in Manila — are among the most celebrated rivalries in sports history.
