Carlos Ulberg knocks out Jiri Prochazka, wins vacant UFC title

Carlos "Black Jag" Ulberg scored a statement knockout while visibly compromised, stopping former champion Jiří Procházka at 3:45 of the first round to claim the vacant UFC light heavyweight title at UFC 327 in Miami. The finish, recorded as KO/TKO from a left hook to the chin and ground strikes, came after Ulberg appeared to blow out his right knee early in the exchange and still found the one shot that decided the fight.

The stakes were high: the bout headlined UFC 327 at the Kaseya Center on April 11, 2026, for a belt vacated when Alex Pereira moved toward heavyweight in late February 2026. Ulberg improved his record to 15-1 with the victory; Procházka entered as a former light heavyweight champion who had won the belt at UFC 275. After the stoppage Procházka said he felt "mercy" and publicly asked for a rematch, underscoring immediate debate about whether the title picture will be settled by another meeting.

Ulberg addressed the injury in post-fight remarks, saying, "I blew out my knee, but I never, ever counted myself out," a line that crystallized the night as an upset defined by adversity. The dramatic finish also carried tangible rewards: under the promotion's new bonus structure, Ulberg earned a $100,000 Performance of the Night award. Josh Hokit earned both Fight of the Night and Performance of the Night bonuses for his heavyweight decision over Curtis Blaydes, collecting two $100,000 awards for a $200,000 total.

The knockout raises immediate questions about fighter safety and corner decision-making. Ulberg fought through a compromised right knee in a title tilt before returning to his corner, and the visible nature of the injury means the champion, his corner and UFC medical staff will be scrutinized for the timeline to evaluation and any surgery. Those medical and managerial decisions will also affect whether Ulberg can accept a rapid rematch or must be sidelined for rehabilitation.

UFC 327 packed the Kaseya Center, with roughly 17,741 in attendance and a reported gate near $7 million, and the event drew wider national attention when President Donald Trump attended cageside. The card produced other notable outcomes that shaped the night: Paulo Costa scored a knockout of Azamat Murzakanov, Josh Hokit defeated Curtis Blaydes in a heavyweight classic, and Cub Swanson stopped Nate Landwehr in an emotional finish.

One chaotic round reshaped the division’s hierarchy: with Alex Pereira pursuing heavyweight plans and Procházka pressing for a rematch, Ulberg inherits both the belt and a compressed decision calendar. The coming weeks will center on Ulberg’s medical update, whether the promotion books an immediate rematch with Procházka, and how a champion who won the title on one leg manages the demands of defending a 205-pound crown.
