Smokin' Joe Frazier is one of the greats - Frank Warren

Frank Warren says Joe Frazier will be remembered as one of the most exciting heavyweights of all time.

Warren was speaking before it was announced that Frazier, who had been battling liver cancer, had died at the age of 67.

Former world champion Frazier - known as Smokin' Joe throughout his career - was the first man to defeat Muhammad Ali in 1971, in the first of what became the most-celebrated trilogy in boxing history.
