Arnold Allen, a top-10 featherweight veteran with a 20-4 record, enters this five-round main event at UFC Fight Night in Las Vegas seeking to halt a skid of three losses in his last four outings, including a unanimous decision defeat to Jean Silva in January. The 32-year-old Englishman brings elite wrestling, cardio, and experience against ranked competition, though recent layoffs and ring rust have hampered his output. Melquizael Costa, ranked No. 12 at 26-7, arrives on a six-fight win streak capped by a February knockout of Dan Ige, showcasing explosive striking and finishing power that has elevated his status. Both fighters made weight without issue, setting up a classic veteran-versus-rising-contender clash at the Apex where Allen’s grappling edge faces Costa’s momentum and knockout threat.
