The ride to UFC 311 had some last-minute bumps in the road when would-be lightweight title challenger Arman Tsarukyan suffered a back injury Friday that forced his withdrawal from a main-event rematch with champion Islam Makhachev, resulting in a Renato Moicano detour on a 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.

Islam Makhachev (26-1 MMA, 15-1 UFC) defends his lightweight title in a rematch against Arman Tsarukyan (22-3 MMA, 9-2 UFC) in Saturday’s main event (pay-per-view, ESPNews/Disney+, ESPN+) at Intuit Dome.
