Mixed Martial Arts fighter Sedriques Dumas was defeated by Luis Hernandez via first-round submission at UFC Fight Night: Rosas Jr. vs Barcelos on September 26, 2026. The light heavyweight bout saw Hernandez secure the submission victory just 57 seconds into the first round, as reported by UFC.com.
Bout Details and Opponent Change
Prior to this definitive loss, Dumas had been slated for a middleweight bout at UFC Vegas 121, which took place on a recent Saturday. His initial opponent was Mickey Gall, who was returning to the Octagon after a two-year absence, as detailed by Sports Illustrated. Gall, a UFC roster member for over 10 years with a 7-7 professional MMA record and a four-fight skid, was unfortunately pulled from the event just two days prior. According to Sports Illustrated, Gall informed fans that his withdrawal was due to “something coming up in his pre-fight medical evaluation,” a detail also noted by Sherdog.
Following Gall’s medical withdrawal, Luis Hernandez, a recent Dana White’s Contender Series contract winner, stepped in on short notice to face Dumas at UFC Vegas 121. This opponent change for Dumas was for a middleweight bout, with Dumas reportedly preparing to welcome Hernandez to the UFC.
Sedriques Dumas’ UFC Journey
Known as “The Reaper,” Sedriques Dumas secured a UFC contract in 2022 following a 47-second submission win on Dana White’s Contender Series, which extended his professional MMA record to 7-0. His tenure in the UFC has since seen mixed results, with his most recent win dating back over two years against Denis Tiuliulin. Dumas entered his recent bouts on a three-fight streak of stoppage losses, only interrupted by a 51-second No Contest against Zach Reese in September of the previous year.
Luis Hernandez’s Emergence
Luis Hernandez, nicknamed “The Stache,” brought a perfect 8-0 professional record into his UFC debut against Dumas, having finished every opponent since his 2021 debut. His short-notice call-up came less than two weeks after his contract-winning performance against Hugo Guillon on Week 6 of Dana White’s Contender Series, where he rallied from a near-submission to finish Guillon with a rear-naked choke in the second round. Hernandez had also secured a second-round submission against Mules Hunsinger at Tuff-N-Uff 145 last June.
