New Zealand mixed martial arts veteran Mark Hunt has unleashed a tirade of verbal assaults at former UFC heavyweight champion Fabricio Werdum ahead of his bout at UFC Fight Night in Russia.
Hunt is headlining the UFC event at Moscow's Olympic Stadium, set to fight Alexei Oleinik on Sunday (NZ time).
He told media he was excited to fight in Russia and was extra pleased to fight someone close to his age.
"He's a clean fighter, so it's great,” said Hunt.
The 44-year-old has had a long battle against performance enhancing drugs after facing a rivals who had failed tests, namely former champion Brock Lesnar.
Hunt unloaded a war of words on Werdum after he was handed a two-year suspension by the US Anti-Doping Agency.
"I'm glad that Fabricio Werdum got caught, that little b****," said Hunt.
"Go back to the favelas. F*** you, you little c***. Good job. He was supposed to be here, but that's what you get for being weak. That's what you get, Fabricio, for being a weak-minded person. See you later."
Werdum was meant to face Oleinik in Russia but was withdrawn after an out-of-competition test conducted in April showed the steroid trenbolone and metabolite epitrenbolone in his sample.
Hunt has fought several fighters who have failed drug tests - Lesnar, Frank Mir and Antonio "Bigfoot" Silva.
His UFC 180 fight with Werdum is topical, with the Brazilian fighter going on to win the UFC's interim heavyweight belt and then going on to beat Cain Velasquez for the undisputed heavyweight title.
"I had to lose 21 kilograms in three and a half weeks to make that a title fight," Hunt said.
"I got kneed in the head by that little cheater. Then he beats Cain in Mexico. That really upsets me about that guy.
"Then he wouldn't fight me – he's just a cheating little b***, man. He's a little dog, that guy. See you later, Fabricio. Enjoy, mother f*****.”
Hunt has a MMA record of 13 wins 12 losses and 1 draw with eight wins in the UFC, six losses and one no contest bout.
