Former undisputed UFC light heavyweight champion, Vitor Belfort has been branded as the “biggest kn*bhead” in the entirety of combat sports by fellow ex-Octagon titleholder, Michael Bisping — who pointed to his prior steroid abuse history.
Belfort, who also won the heavyweight tournament at UFC 12, faced off with former middleweight champion, Bisping back in 2013 in a grudge fight main event in his native Brazil.

And stopping the British veteran with a hellacious second round stoppage, Brazilian star, Belfort scored a brutal high kick stoppage win, before stopping the duo of Luke Rockhold, and Dan Henderson with knockouts en route to an unsuccessful title charge against then-champion, Chris Weidman.
