Ultimate Fighting Championship (UFC) is just over 24 hours away from its upcoming UFC Vegas 117 mixed martial arts (MMA) event, headlined by a 145-pound showdown between featherweight contenders Arnold Allen and Melquizael Costa. The action gets underway this Sat. night (May 16, 2026) on Paramount+ from inside the promotion’s Meta Apex facility in Las Vegas, Nevada, and also features a 145-pound co-headliner between featherweight title hopefuls DooHo Choi and Daniel Santos.
