Nurmagomedov, one of the best former lightweight champions in the sport, has become an incredible coach. At UFC 311, he will be in the corner of Islam Makhachev, who will no longer defend his title against Arman Tsarukyan but instead, Renato Moicano.

As a result of Tsarukyan's dropout, lightweight contender Renato Moicano is stepping into the main to challenge Makhachev for the 155-pound title on short notice. Moicano was previously scheduled to face fellow veteran contender Beneil Dariush on the pay-per-view card.

Makhachev won the UFC lightweight title by submitting Charles Oliveira in 2022. He defended his title twice in a row against former featherweight champion Alexander Volkanovski and then he submitted Dustin Poirier back in June. That said, he might be facing his toughest challenger in Tsarukyan tomorrow night.
