Arnold Allen and Melquizael Costa were scheduled to meet in a featherweight main event at a UFC Fight Night on May 16 in Las Vegas, according to recent schedule listings. The matchup places Allen, a longtime contender looking to rebound and reassert himself, against Costa, an ascending fighter seeking a signature win. Set at the Meta APEX facility, the event continues the UFC’s trend of mixing established names with prospects in smaller-venue cards. A strong showing from either man could propel the winner into the thick of the featherweight title conversation. The card is part of the UFC’s 2026 slate airing on Paramount+.
