Dana White has officially announced that Arman Tsarukyan will serve as the backup fighter for the Ilia Topuria versus Justin Gaethje bout at UFC White House. Earlier this week, Tsarukyan had expressed his readiness to step in as a replacement for either fighter if needed. However, he specified that he would not cut weight in preparation for the backup role, suggesting at the time that he may have only been planning to serve as backup rather than having confirmation. The announcement ensures continuity for the high-profile lightweight title fight should either main event participant be unable to compete.
