Sedriques Dumas Faces Luis Hernandez

Sedriques Dumas will still compete at UFC Vegas 121 on Saturday, but the opponent standing across from him has changed late in fight week. Mickey Gall has withdrawn, and the UFC announced Thursday that Luis Hernandez will take his place against Dumas with two days remaining before the card. The change keeps Dumas on the event after Gall, who had been preparing for his first fight in nearly two years, was removed because of medical issues. Gall said the problem appeared during his fight-week medicals and added that he was fine. Rather than losing his place on the show, Dumas now moves forward with a newly signed, unbeaten opponent.

The adjustment brings a very different recent resume into Dumas’s scheduled bout. Hernandez owns an 8-0 record and earned his UFC contract earlier this month through Dana White’s Contender Series. In that appearance, he finished Hugo Guillon with a rear-naked choke in the second round. His UFC Vegas 121 assignment will put him back in the octagon only 11 days after that win, a turnaround identified as one of the fastest in DWCS history. Dumas had been booked to meet Gall, but the promotion has replaced the withdrawn fighter instead of cancelling the matchup. The larger event also remains in place as a 12-bout card. For readers tracking the late change, the essential sequence is Gall’s withdrawal during fight week, Thursday’s confirmation of Hernandez as the replacement, and Dumas retaining his Saturday date at UFC Vegas 121.

A replacement keeps Dumas active

Dumas enters the revised contest with a 10-5 record and a clear objective: ending a four-fight winless stretch. Three of those results were stoppage defeats. His last victory came in August 2024, when he beat Denis Tiuliulin by unanimous decision. Those results remain the backdrop to a fight that changed opponents just before the event, although the immediate outcome of the UFC’s announcement is straightforward: Dumas remains scheduled to compete.

Hernandez arrives under different circumstances. He is unbeaten at 8-0, has only recently joined the UFC, and is making the rapid return following his Contender Series performance against Guillon. The second-round rear-naked choke was the win that secured his contract earlier this month. Now he replaces Gall on two days’ notice for Saturday’s card. The switch does not provide Dumas with the original matchup, but it does preserve the opportunity to fight. Gall’s absence was attributed by the UFC to medical issues, while Gall’s own explanation was that something arose in his fight-week medicals. No further detail about that issue was provided in the available information. The confirmed update is therefore focused on the new opponent and Dumas’s continued inclusion at UFC Vegas 121.

The late reshuffle can be read through several confirmed points without extending beyond what has been announced. Dumas was not pulled from the event when Gall withdrew. Hernandez, fresh from earning a UFC deal, accepted the replacement assignment. And the card continues with 12 bouts despite the change. Together, those details explain why the bout now pairs a fighter looking for his first win since August 2024 with a newcomer coming off a contract-winning submission.

The timing also distinguishes Hernandez’s situation. He fought on Dana White’s Contender Series 11 days before this return to the octagon, following the second-round rear-naked choke finish of Guillon. That short interval is described as one of the quickest turnarounds in DWCS history. Dumas, meanwhile, remains attached to the event after the final-days disruption to his original booking. Key confirmed details of the replacement are: – Gall withdrew from UFC Vegas 121 because of medical issues that he said emerged during fight-week medicals. – Dumas stays on Saturday’s card and now faces Hernandez rather than Gall. – Hernandez brings an 8-0 record after signing with the UFC earlier this month through his Contender Series win. – UFC Vegas 121 proceeds as a 12-bout event.

What remains set for UFC Vegas 121

Dumas versus Hernandez is part of a UFC Vegas 121 lineup that remains intact at 12 bouts. The event is topped by Raul Rosas Jr. against Raoni Barcelos in a bantamweight main event. Rodolfo Vieira faces Robert Bryczek in the co-main event, a 185-pound matchup. Dumas’s contest stays on that card despite Gall’s withdrawal and the short notice needed to install a replacement. The available details establish the contrast around the new pairing without predicting an outcome. Dumas is 10-5 and seeking to stop a four-fight winless run that includes three stoppage losses. Hernandez is 8-0 and comes directly from a successful Contender Series appearance, where he submitted Guillon with a second-round rear-naked choke.

His 11-day turnaround follows the performance that brought him into the UFC. The table below separates the central confirmed facts from the broader event context. Confirmed item | Available detail Dumas’s status | He remains scheduled for UFC Vegas 121 after Gall withdrew. Replacement opponent | Hernandez replaces Gall and enters with an 8-0 record. Hernandez’s UFC entry | He signed earlier this month after submitting Hugo Guillon in the second round on Dana White’s Contender Series. Card status | UFC Vegas 121 will continue with 12 bouts. Gall had been set for his first appearance in nearly two years before the medical issue ended his participation. His statement said he was fine, but the reported material does not offer additional specifics. As a result, the firm conclusion is limited to the announced substitution: Dumas remains on the Saturday event, and Hernandez takes the available spot.

• Gall withdrew because of medical issues that he said surfaced in fight-week medicals.
• Dumas remains on UFC Vegas 121 and faces replacement Luis Hernandez on Saturday.
• Hernandez returns 11 days after his Dana White’s Contender Series victory over Hugo Guillon.

A late fight-week withdrawal has changed Sedriques Dumas’s opponent, not his UFC Vegas 121 assignment. Mickey Gall is out because of medical issues, while Luis Hernandez steps in after earning his UFC contract earlier this month. Dumas takes a 10-5 record and a four-fight winless skid into the revised matchup; Hernandez arrives unbeaten at 8-0, only 11 days removed from his Contender Series submission of Hugo Guillon. The Saturday card will proceed with 12 bouts.
