Undefeated British fighter Muhammad Mokaev and former UFC heavyweight champion Junior Dos Santos will feature on the undercard of Ronda Rousey's comeback against Gina Carano on May 16 at the Intuit Dome in Los Angeles. Mokaev, widely regarded as the top unsigned flyweight prospect globally, will face Adriano Moraes in an MMA bout.

Mokaev, who moved to England after his mother's death, built an impressive 23-0 amateur record before turning professional. The 23-year-old Manchester-based fighter has remained unbeaten in the pro ranks, with seven victories coming in the UFC. Moraes, a multiple-time ONE Championship flyweight world champion, brings extensive experience as the promotion's first-ever flyweight titleholder.

Dos Santos will battle Cuba's Robelis Despaigne in a heavyweight contest. The Brazilian legend captured the UFC heavyweight title in 2011 by defeating Cain Velasquez in just 64 seconds, showcasing the elite boxing and knockout power that defined his career. Dos Santos has faced top-tier competition including Stipe Miocic, Alistair Overeem, and Francis Ngannou throughout his storied tenure in the sport.
