Carlos Ulberg defeated Jiri Prochazka at UFC 327 with his signature left check hook, marking his sixth knockout with that specific strike in his last 12 fights. Prochazka was caught by the check hook three times before the final knockout, despite having previously been dropped twice by the same punch against Alex Pereira. The analysis notes Ulberg's superior mobility, precision, and counter-striking compared to previous Prochazka opponents like Rakic, Roanhorse, and Oezdemir. Prochazka also sustained a knee injury during the fight but failed to capitalize through wrestling or leg kicks. The post suggests a potential Ankalaev vs Ulberg matchup, giving Ankalaev 55-45 odds despite Ulberg's speed and movement advantages.
Carlos Ulberg delivered a stunning knockout of Jiri Prochazka at UFC 327 on April 11, finishing the Czech contender with his signature left check hook to move to 15-1 and cement himself as a genuine light heavyweight title contender.
The New Zealand-based City Kickboxing product, nicknamed "Black Jag," has now landed that specific punch as the finishing blow in six of his last 12 fights. Ulberg, 35, stands six-foot-four with a 77-inch reach and posts an impressive 6.54 significant strikes landed per minute at 55 percent accuracy — numbers that reflect the sharp, high-volume counter-striking game he put on full display against Prochazka. He entered the fight ranked third in the light heavyweight division.
Prochazka, ranked second, came in at 32-6-1 and is one of the more dangerous offensive fighters in the division, averaging 5.69 significant strikes per minute himself. The 33-year-old Czech fighter, who stands six-foot-three with an 80-inch reach, had previously been dropped twice by the same left check hook in his losses to Alex Pereira, yet the pattern repeated itself at UFC 327. According to the post-fight analysis, Prochazka was caught by the check hook on three separate occasions before Ulberg finally finished him, with Ulberg's superior mobility and precision proving to be the decisive edge over opponents Prochazka had previously handled, including Rakic, Roanhorse, and Oezdemir. A knee injury Prochazka sustained during the fight further complicated his night, though he was unable to pivot toward wrestling or leg kicks to neutralize Ulberg's countering game.
Why it matters
- Ulberg's win over a top-two contender vaults him into title conversation at 185 pounds above the crowded light heavyweight field
- Prochazka's recurring vulnerability to the left check hook raises serious questions about his path back to championship contention
- The most logical next step appears to be Ulberg against number-one ranked Magomed Ankalaev, who carries a 21-2-1 record and sits fifth in the pound-for-pound rankings — a matchup that would pit Ulberg's speed and movement against Ankalaev's wrestling-heavy, grinding style
