Carlos Ulberg claims UFC light heavyweight title with first-round knockout

Carlos Ulberg captured the vacant UFC light heavyweight championship with a first-round knockout of Jiří Procházka at Kaseya Center in Miami, stopping the former champion after an injury-marred opening round. Ulberg’s finish came amid dramatic visuals: he appeared to suffer a right-knee injury early in Round 1 and still landed the decisive blow to end the fight.

The sequence unfolded quickly. Procházka and Ulberg exchanged at range, Ulberg then visibly compromised his right knee, and at roughly 3:45 of Round 1 the New Zealander connected with a left hook that put Procházka out and awarded Ulberg the title. The stoppage concluded a main event that had been billed as No. 2 Jiří Procházka versus No. 3 Carlos Ulberg for the vacant, undisputed light heavyweight crown.

Those rankings and the championship stakes were part of UFC 327’s promotional card for the April 11, 2026 event; the promotion listed the card at Kaseya Center in Miami and scheduled broadcast windows for Paramount+ with the main card beginning at 9:00 p.m. ET. The vacant title had been on the line following Alex Pereira’s departure from the division, and the win pushes Ulberg into undisputed champion status in the 205-pound class.

UFC 327’s results night also produced a separate judging controversy that exposed the mechanics of scorekeeping. On the early prelims, the lightweight bout between Chris Padilla and MarQuel Mederos was initially announced as a majority decision win for Padilla, but the UFC later disclosed a scoring error and corrected the result to a majority draw. The reversal followed an official review of the three judges’ cards and a one-point deduction for Mederos in Round 3 for an eye poke.

The official scorecards explain why judges diverged. On the published cards, one judge recorded Padilla 29-27, while two cards totaled 28-28 after the deduction, producing a majority draw. Round-by-round tallies show Round 1 was scored 10-9 largely for Padilla, Round 2 was split and close across scorecards, and Round 3 generated the largest variance: media tallies leaned toward a 10-8 for Padilla on many watches, but the referee’s deduction to Mederos created 9-9 outcomes on at least one official card and flipped the arithmetic that would have given Padilla a clear margin. That mix of a close Round 2 and a scored-and-deducted Round 3 is the literal arithmetic that turned an announced decision into a draw when score totals were corrected.

The Padilla–Mederos episode points to realistic fixes fight commissions and promoters can adopt: require immediate, visible publication of all three judges’ handwritten cards before announcing results, implement a redundant electronic tally that cross-checks totals, and mandate that any round-ending deductions be logged and verified on broadcast screens prior to result calls. Those steps would not alter how rounds are judged under 10-point-must criteria, but they would reduce clerical errors that change outcomes after fans and fighters have already reacted. The UFC’s acknowledgment of the correction underlines the narrow failure mode: correct judging data existed, but tabulation and communication failed in the broadcast window.

UFC 327 also provided a farewell moment on the main card: veteran featherweight Cub Swanson, 42, made his final walk and scored a first-round knockout over Nate Landwehr in what the promotion framed as his retirement fight. The night drew high-profile attention in Miami, where President Donald Trump attended the Kaseya Center main card and was visible among ringside figures for the Procházka-Ulberg headliner.

Carlos Ulberg’s title win closes one dramatic chapter in Miami and leaves several others open: the light heavyweight division now has a new champion who won under extraordinary physical strain, and athletic commissions will face renewed pressure to tighten scorekeeping and result-verification protocols after the Padilla–Mederos correction.
