It was Nurmagomedov’s latest jab at McGregor. The two had one of the more infamous UFC dramas in the company’s history. Nurmagomedov beat McGregor at UFC 229 in 2018 after McGregor hurled insults toward Nurmagomedov in the days and weeks leading up to the fight.

McGregor lost to Nurmagomedov via submission. Nurmagomedov climbed the cage and leaped at the men in McGregor’s corner, setting off a prolonged brawl inside and outside the octagon. Meanwhile, two men from Nurmagomedov’s entourage climbed into the cage and attacked McGregor, who defended himself before security personnel rushed in to restore order.

Tensions are still high between the two.

Nurmagomedov retired from fighting last year after beating Justin Gaethje.
