Mickey Gall Pulled From UFC Vegas 121 on Medical Grounds

Mickey Gall's comeback fight at UFC Vegas 121 is off after the promotion pulled him from his middleweight bout against Sedriques Dumas for medical reasons. Gall said he found out Thursday, Sept. 24, when the UFC told him something on his pre-fight medical tests made him ineligible to compete this weekend. Dana White's Contender Series graduate Luis Hernandez has stepped in on short notice to face Dumas instead.

What Happened to Mickey Gall's UFC Vegas 121 Fight

Mickey Gall was set to end nearly two years away from the cage this Saturday against Sedriques Dumas, but the UFC scratched him from the card over an undisclosed medical issue. Gall addressed the withdrawal directly on Instagram, saying, "Something came back on my medicals that [is] making me ineligible via simple procedure." He added that he was told he was otherwise fine, and framed the setback as fixable rather than career threatening, telling fans, "I will be back."

For Gall, the timing stings. The 34-year-old hasn't won a fight since 2021 and has been out of action since 2024, and he said he'd worked hard to give his fans something to cheer for this weekend. Gall made his UFC debut in just his second pro fight back in 2016 and opened his run with three straight finishes before sliding into a four-fight winless stretch that's kept him off UFC cards for the better part of two years.

Luis Hernandez Steps In Against Sedriques Dumas

Luis Hernandez takes the short-notice assignment against Sedriques Dumas just 11 days after finishing Hugo Guillon on Dana White's Contender Series, one of the fastest DWCS-to-Octagon turnarounds in the show's history. Hernandez is unbeaten at 8-0 and signed with the UFC on the strength of that Contender Series performance, a second-round rear-naked choke.

Dumas, at 10-5, is trying to snap a four-fight winless skid that includes three stoppage losses. He hasn't won since a unanimous decision over Denis Tiuliulin in August 2024, so this fight still carries real stakes for him regardless of who's standing across the cage.

Betting Angle

Swapping a rusty veteran in Mickey Gall for an undefeated prospect on an 11-day turnaround changes the shape of this line significantly. Sedriques Dumas now likely opens as a betting underdog against fresh, motivated opposition rather than facing a fighter who hadn't competed in almost two years, and books will be watching closely for how much value oddsmakers put on Hernandez's inexperience against a durable veteran finisher's record. Bettors who liked Dumas as a live dog against Gall should reassess the matchup entirely rather than assume the number holds.

UFC Vegas 121 still runs its full 12-fight card, headlined by a bantamweight main event between Raul Rosas Jr. and Raoni Barcelos, with Rodolfo Vieira facing Robert Bryczek in the co-main event at middleweight.
