Ulberg’s one‑leg KO

Carlos Ulberg won the Ultimate Fighting Championship light heavyweight title on April 11, stopping Jiří Procházka at 3:45 of the first round after his right knee appeared to give way in Miami. (ufc.com) (espn.com) The fight headlined UFC 327 at Kaseya Center, where the division’s belt was vacant and both men entered as top-three contenders. ESPN listed the finish as a punch knockout technical knockout, and Ulberg’s record moved to 15-1 while Procházka fell to 32-6-1. (ufc.com) (espn.com) Ulberg said afterward that he had “blew out” his knee early in the round, and video of the exchange showed his leg buckle before Procházka pressed forward. CBS Sports reported that Procházka then walked into Ulberg’s left hook, the punch that ended the title fight. (cbssports.com) (mmajunkie.usatoday.com) The result reshaped a division that had been left without a champion before UFC 327, with Procházka and Ulberg booked to fill that vacancy. Ulberg came in ranked No. 3 by the promotion and had last fought in September 2025, when he knocked out Dominick Reyes in the first round. (ufc.com 1) (ufc.com 2) Ulberg also extended the run that made him a title challenger in the first place. Before UFC 327, the promotion listed him at 14-1 with eight knockout wins and seven first-round finishes, and reports ahead of the fight described him as riding a nine-fight winning streak. (ufc.com) (bjpenn.com) For Procházka, the loss ended another attempt to regain the 205-pound belt. CBS Sports reported that Ulberg became the first fighter other than Alex Pereira to beat Procházka in the Ultimate Fighting Championship, after Pereira had stopped him for the same vacant title at UFC 295 in November 2023. (cbssports.com) (ufc.com.br) Procházka said in a hospital video after the fight that his “stupid mercy” cost him the title and that he wanted a rematch. Bloody Elbow quoted him saying, “I would like to fight a rematch, because that was my fight,” while Ulberg answered at the post-fight press conference that Procházka “made a mistake there.” (bloodyelbow.com) Daniel Cormier posted an octagon-side reaction video within hours, and the finish quickly spread across mixed martial arts coverage as one of the night’s defining clips. By Sunday morning, outlets from Yahoo Sports to MMA Junkie were leading with the same detail: the new champion had won on one damaged leg. (sports.yahoo.com) (mmajunkie.usatoday.com)
