LOS ANGELES – UFC 311 took an unexpected major turn Friday morning, with Arman Tsarukyan withdrawing from his lightweight title fight against Islam Makhachev. A new UFC 311 main event is now set as Renato Moicano will step in to challenge Makhachev (26-1 MMA, 15-1 UFC) for the belt.

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.

Arman Tsarukyan's nearly six-year journey to the UFC lightweight title will take a little longer. Tsarukyan suffered an injury two nights before challenging lightweight champion Islam Makhachev at UFC 311.
