Conor McGregor vs. Khabib Nurmagomedov

Conor McGregor and Khabib Nurmagomedov’s rivalry is one of the most heated in the history of the sport, to the extent that there were violent scenes even immediately after they fought at UFC 229 last year.

Then months later came a new low-point in the bitter war of words between the two when ‘The Notorious’ stooped to mocking Nurmagomedov’s wife and religious beliefs.

“Your wife is a towel mate,” McGregor wrote alongside a picture of Nurmagomedov’s wife from her wedding day, wearing a traditional wedding dress.

“Rapist, you are Rapist,” Nurmagomedov fired back, referencing an ongoing investigation into a rape allegation against McGregor.

The trash-talk had clearly got out of hand and Dana White had to personally step in to calm the hostilities between the two parties.

“I feel like if it keeps escalating the way it is, somebody is going to end up getting hurt or shot,” UFC middleweight title contender Kelvin Gastelum warned at the time.
