For two rounds, Cortes-Acosta’s plan looked like the right one. The favourite marched forward, looked for openings to the head, landed the heavier shots and controlled the grappling exchanges, while Walker tried to keep his distance, chopping at the legs with kicks and searching for angles for his unorthodox striking. Then, in the third, the fight turned on a single shot: Walker caught Cortes-Acosta with a hard right hand that dropped him, and followed up until the referee stepped in. “This is not technique,” Walker said afterward, describing the finishing moment as pure instinct. Both men earned $100,000 Fight of the Night bonuses.
The result reshapes both men’s paths. Walker, now 24-10 with one no contest, has two straight stoppage wins since moving up from light heavyweight, following his first-round knockout of Mick Parkin at UFC 332 in October, and he suddenly has a route toward the top of a heavyweight division still reorganising itself around new champion Ciryl Gane. For Cortes-Acosta, the slide continues. After starting his UFC career 10-2 and opening 2026 with a stoppage of Derrick Lewis, the Dominican heavyweight has now lost three straight, following decision defeats to Alexander Volkov and Curtis Blaydes, and falls to 17-5.
The co-main event went the full three rounds. Tatiana Suarez beat Virna Jandiroba by unanimous decision, 30-27, 30-27 and 29-28, in a meeting of two former title challengers that strengthens Suarez’s case for another shot at the strawweight title.
The quickest finish of the night came from Elijah Smith, who needed just 60 seconds to knock out veteran Davey Grant at bantamweight. There was an upset at middleweight, where Andre Petroski beat Mantas Kondratavicius, one of the card’s biggest favourites. Lucas Fernando beat Billy Elekana at light heavyweight, Nina Nikolija Milošević defeated Priscila Cachoeira at women’s bantamweight, and Ko Seok-hyeon got past Wellington Turman at welterweight. On the prelims, Karine Silva beat Gabriella Fernandes, and Murtazali Magomedov, Austin Bashi, Oliver Schmid, Mitch Raposo, Thomas Petersen and Jose Henrique Souza also won. The UFC handed out four $100,000 bonuses in total.
A card that lost its welterweight headliner when Sean Brady withdrew with a knee infection ended up producing one of the more dramatic finishes of the autumn. Walker said yes to a fight nobody expected him to take this soon, survived two difficult rounds and found the punch that changed everything. At heavyweight, he is suddenly a name the division has to take seriously.
