Set to take place at the Intuit Dome in Los Angeles, CA, UFC 311 was supposed to feature a rematch between UFC Lightweight Champion Islam Makhachev and Arman Tsarukyan in the night’s main event after the undefeated Umar Nurmagomedov challenges UFC Bantamweight Champion Merab Dvalishvili in the co-main event.

Arman Tsarukyan has been forced out of the main event at UFC 311, with Brazil's Renato Moicano stepping in to challenge Islam Makhachev on one day's notice.

Dana White announced a major change to the UFC 311 pay-per-view card this Saturday in Los Angeles.

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.
