Tony Ferguson Mocks Khabib Nurmagomedov's Unbeaten Record In Scathing Instagram Comment

But 'El Cucuy' won't let the feud die and he left a comment on Instagram which disputes Nurmagomedov's 29-0 record.

"All before UFC. To be professional fighter in most fight leagues, There must be three sanctioned rounds to be considered professional. Fights league such UFC & farm league.

"The 3x two round TUF fights should count on my record of that is the case. Give me three more knockouts and victories on my record."

Nurmagomedov stepped away from the Octagon back in October after defeating Justin Gaethje at UFC 254 in an emotional affair.

Ferguson himself suffered a defeat to Gaethje at UFC 249 in May and Khabib insisted the punishment he took in that fight meant he would 'never be the same again.'

"Nobody can be same long time -- no Tony Ferguson, no Khabib, nobody.

"And one day somebody gonna beat you or something gonna happen. God don't give to nobody free power, reaction, mental, everything in one level always. One day it's gonna go down.

"And his day come, it was in May. Tony Ferguson's time is finished. How he gonna come back?

"Someone gonna beat him again, I believe, because when you take damage like this you never gonna be same, never ever, even if you're Tony Ferguson.

"He take too much damage. You see how he give up at end of the fight, he go like this."

Ferguson would return to the UFC in December and suffer a unanimous decision loss to Charles Oliveira.
