An injured Arman Tsarukyan has been replaced in the main event of UFC 311, with Renato Moicano now challenging Islam Makhachev for the lightweight title – on one day’s notice.
Tsarukyan was due to face Makhachev on Saturday (18 January), six years after losing to the Russian via decision in a competitive fight. But a back injury prevented Tsarukyan from weighing in on Friday, and Moicano was drafted in for the Armenian-Russian, having already been scheduled for UFC 311.
