Luis Hernandez VS Sedriques Dumas

Luis Hernandez defeated Sedriques Dumas by submission (guillotine choke) at 0:57 of round one at UFC Fight Night: Rosas Jr. vs. Barcelos in Las Vegas on September 26, 2026. Hernandez opened with an overhand left, immediately pulled to the clinch, secured top position, and snatched a guillotine — standing to crank it until Dumas tapped. The finish arrived so quickly that Dumas barely had a chance to settle into his stance, making Hernandez's positional aggression and submission instincts the only story of the fight. Hernandez had entered on two days' notice, having earned his UFC contract just eleven days earlier at Dana White's Contender Series, and extended his unbeaten professional record with a ninth consecutive stoppage win. Dumas had dropped four of his last five outings entering the bout.

Miami-Dade Sheriff's deputy Luis Hernandez (8-0) makes his UFC debut on under three days' notice, just 11 days after earning his contract with a second-round rear-naked choke of Hugo Guillon on Dana White's Contender Series. He replaces Mickey Gall (out with a medical issue) against Sedriques Dumas (10-5, 1 NC), who is winless in his last four and was submitted in each of his last two fights. The bout moved up to light heavyweight, where Hernandez weighed in seven pounds heavier (204 to 197), and Dumas badly needs a win to stop the slide.
