Dana White has announced that Arman Tsarukyan is the official backup fighter for the Ilia Topuria vs Justin Gaethje bout at UFC White House. Earlier this week, Tsarukyan had expressed his readiness to replace either fighter if needed, but clarified he would not cut weight ahead of the fight. The backup designation was not yet official at that time, suggesting he may have been planning for the role. Having an official backup ensures the main event can proceed even if one of the original fighters is unable to compete. The announcement provides security for one of the most anticipated fights on the card.
