Khabib Nurmagomedov was not happy with Conor McGregor’s coach’s comments on Islam

Conor McGregor might have the most hype, but Khabib Nurmagomedov could just be the hardest man in the UFC.

The Russian lightweight returned to action after a two-year absence with a comprehensive second-round TKO of Darrell Horcher on Saturday night to take his professional record to an undefeated 23-0. Nurmagomedov's return to the octagon has people already talking about a re-match with current lightweight champion Rafael dos Anjos in what would be a mouth-watering title fight. The pair faced off two years ago, with Nurmagomedov taking the win by unanimous decision. But in the Russian's absence, RDA has claimed the lightweight crown. Fans looking forward to a re-match will have to wait, though. Nurmagomedov's Muslim faith means a summer bout will not be possible as the 27-year-old will be fasting for Ramadan - which begins on June 7 this year - and will need time to prepare a full camp. https://twitter.com/arielhelwani/status/721504008280621056 While it's admirable that Nurmagomedov is so devout in his faith that he may forgo a title shot in order to observe Ramadan, one person who is not so impressed is Conor McGregor's coach, John Kavanagh. McGregor has made a name for himself as a regular fighter, taking on last-minute opponents in half of his eight UFC fights to date, and clearly Kavanagh was underwhelmed by Nurmagomedov's decision to put his faith over his career. https://twitter.com/John_Kavanagh/status/721504547156463616

Unsurprisingly, the Russian lightweight did not take this well.

Kavanagh tried to keep things light, but Nurmagomedov was not interested.

And while Kavanagh apparently learned something new about discussing religion online, all we could think about is how great a Nurmagomedov vs McGregor fight would be.
