London, Jan. 26: Former World Heavyweight Boxing Champion Evander Holyfield has said that 280 pounds, his main rival Mike Tyson cannot fight even if he wants to.

"Tyson is walking around at something like 280lbs and couldn't fight if he wanted to. Anyway he's a coward," The Sun quoted Holyfield, who beat Tyson twice, as saying.

The ex-world heavyweight champ has said that he won't quit the boxing ring until he wins the title for a fifth time. He recently lost on points to the "Beast from the East" Nikolay Valuev.

A third fight between Holyfield, 46, and Tyson has been dismissed by Holyfield's manager Ken Sanders. (ANI)
