Jiri Prochazka took to social media from a hospital bed in the hours after UFC 327, posting a message to fans following his first-round knockout defeat to Carlos Ulberg on April 11, accepting full blame for the loss and calling for a rematch.
The Czech striker, ranked second in the light heavyweight division, absorbed Ulberg's signature left check hook to suffer one of the more stunning setbacks of his career. Prochazka, 33, was having his jaw evaluated at the time of the post. The former light heavyweight champion acknowledged that he handed Ulberg the opening, writing that he "just gave him the opportunity to catch me" and making clear he believed "only he is to blame for this result." Despite the setback, the 32-6-1 veteran made his desire for a rematch explicit. Fighting out of Jetsaam Gym Brno, Prochazka stands six-foot-three with an 80-inch reach and produces 5.69 significant strikes per minute at 55 percent accuracy — numbers that underline how dangerous he remains even after this loss.
Ulberg, the New Zealand product fighting out of City Kickboxing, improved to 15-1-0 with the finish and now holds a firm claim as the division's most dangerous contender. The 35-year-old, known as Black Jag, stands six-foot-four with a 77-inch reach and leads the division's ranked fighters in striking output at 6.54 significant strikes per minute, also at 55 percent accuracy. Ranked third heading into the night, the victory positions him as a legitimate title challenger.
Why it matters
- Ulberg's win over a former champion at UFC 327 could push him into contention for a light heavyweight title shot.
- Prochazka drops to second in the rankings but remains a marquee name; a rematch would carry significant divisional weight.
- The stylistic contrast — two high-output Orthodox strikers with elite finishing ability — made this matchup compelling and would do so again.
