A Miami-Dade sheriff's deputy stepped into the octagon on barely a day's notice and walked out with a win in less than a minute. Luis “The Stache” Hernandez submitted Sedriques Dumas with a standing guillotine chokehold just 57 seconds into the first round, according to NBC 6 South Florida, capping off a UFC debut that came together almost overnight.
Hernandez made his short-notice debut at UFC Fight Night: Rosas Jr. vs. Barcelos, according to UFC.com, which described the win as quick work courtesy of that first-round finish. As reported by NBC 6 South Florida, Hernandez is a working Miami-Dade sheriff's deputy who took the fight against Dumas, whom the outlet describes as a convicted felon. Hernandez said he got the call from his bosses with just a day and a half's notice, and that he was ready and healthy when the opportunity came.
A Debut Built on Short Notice
This wasn't the first time Hernandez had been asked to fight on the fly. The station's report notes he's previously accepted bouts on three days' and three weeks' notice, and that he'd even said he would take a UFC fight in Utah the following weekend if asked. That willingness to jump in appears to be part of how he landed this particular matchup in the first place, since Dumas had expected to fight another opponent who dropped out because of an injury.
Hernandez accepted the opportunity to make his UFC debut once that slot opened up. As reported by NBC 6 South Florida, he had an undefeated record heading into the bout, and he said making history while serving as a role model mattered most to him.
UFC Framed It as Cop Versus Convict
The promotion leaned into the contrast between the two fighters, with the UFC promoting the matchup as cop versus convict, per the same NBC 6 account. Dumas is a convicted felon, and ESPN.com.sg reported he'd been arrested and charged with multiple felonies in Florida, including battery and robbery. Online records reviewed by ESPN.com.sg listed additional charges against Dumas, including home-invasion robbery, possession of a weapon or ammunition by a convicted felon, and drug possession.
That same ESPN.com.sg report detailed a February 2024 arrest in Escambia County, which it said followed a verbal argument with police after an alleged public disturbance. Dumas was booked into the Escambia County jail and held on $558,500 bond, according to the outlet's reporting. His UFC record stood at 3-3 since he signed with the promotion off Dana White's Contender Series in 2022, per that same report.
Hernandez Pushed Back on the Narrative
Despite the promotional framing, Hernandez used his platform to defend his opponent rather than pile on. He called out online comments targeting Dumas and asked people to treat him with respect, noting that Dumas has a family. Dumas himself had leaned into the matchup's storyline, posting an AI-made video depicting a uniformed police officer and himself in an orange jail jumpsuit dancing together.
The buildup to the fight also drew attention on social media. One Threads user, @mikejbknows, joked about what walkout music the pairing deserved, writing, “Luis Hernandez vs Sedriques Dumas better feature these songs as their UFC walkout music.”
What Comes Next
Following the win, the Miami-Dade Sheriff's Office congratulated Hernandez on the victory, as noted by NBC 6 South Florida. The station's report also carried commentary from Brendan Tobin, a sports talk radio host at WQAM and MMA expert, who discussed the promotion’s matchup framing, Hernandez’s opportunity, and the pressure of facing a convicted felon.
Hernandez's rapid finish adds another chapter to a UFC debut built almost entirely on short notice, from the day-and-a-half call from his bosses to his stated willingness to fight anywhere, anytime the promotion needed him. For now, the deputy leaves the octagon with a win, an undefeated record intact, and a story that's already circulating well beyond South Florida.
