Former heavyweight boxing champion Joe Frazier is dead, a short time after entering a hospice for liver cancer.

More from FOX News Radio's Karyn Regal:

Despite an impressive fight record of 32 - 4 and 1, with 27 knockouts, Frazier's career is forever linked with Muhammad Ali for the three epic battles - the two fought between 1971 and 1975, starting with "The Fight of the Century" and ending with the "Thrilla in Manilla." Over the course of his career Frazier suffered 4 losses, including two to George Foreman. The first Frazier - Foreman fight took place in Jamaica in 1973, with Foreman knocking down Frazier 6 times before the fight was stopped in the second round.
