There has been a development regarding UFC 311 that Dana White and the UFC have just announced. The main event featuring Lightweight champion Islam Makhachev vs the #1 contender Arman Tsarukyan has changed as Arman Tsarukyan injured his back last night. The news broke at about 10am PST on 01/17/2025. The new main event will still feature the champ Islam Makhachev, who will now face top contender Renato Moicano, who was the planned backup for this fight in case any injuries occurred. UFC's first visit to Intuit Dome in Inglewood, California, on January 18 will be a star-studded one, featuring two highly anticipated championship bouts. In the main event of UFC 311, dominant lightweight champion Islam Makhachev puts his belt on the line against the man who gave him one of his toughest tests to date in surging contender Arman Tsarukyan. Plus, the co-main event will see newly-crowned bantamweight champion Merab Dvalishvili face off with unbeaten phenom Umar Nurmagomedov.
