Conor McGregor v Khabib Nurmagomedov: Tony Ferguson wants "double knockout"

UFC fighter Tony Ferguson said he wants a "double knockout" when Conor McGregor faces Khabib Nurmagomedov on Saturday.

Ferguson, 34, was due to defend his interim lightweight title against Nurmagomedov in April, but had a knee injury and had been stripped of the belt.

Nurmagomedov, 30, became champion defeating Al Iaquinta and will make his first defense against McGregor.

"They took my belt, took a series of zeros in my paycheck," Ferguson said. "How do you think I feel?"

The American needed an operation after he tore the lateral collateral ligament a week before he had to fight the Russian Nurmagomedov.

He said: "I am the champion, I have not lost my seatbelt, they have taken it, I have a small shine on my shoulder, it is still there, it weighs a lot . "

Ferguson will return when he fights Anthony Pettis against McGregor-Nurmagomedov's underlying card in Las Vegas.

Asked about his prognosis for the big fight, he added: "Double knockout, I hope that they mutilated themselves."

Ferguson says it's "in his contract" that he will intervene as a late replacement if McGregor or Nurmagomedov withdraw from the fight.
