Carlos Ulberg knocked out Jiri Prochazka at UFC 327, marking his sixth knockout with a left check hook in his last 12 fights. Prochazka was caught by the same punch three times before the finish, similar to his two previous knockdowns against Pereira. Despite Ulberg suffering a knee injury during the fight, Prochazka failed to capitalize or adjust his approach. The analysis suggests a potential matchup between Ulberg and Magomed Ankalaev would favor Ankalaev 55-45, noting that Ulberg's stance and mobility make him vulnerable to leg kicks but also make him a difficult puzzle for opponents. Prochazka's inability to safely close distance proved decisive.
Carlos Ulberg knocked out Jiri Prochazka at UFC 327 on April 11, 2026, using the left check hook that has become his most reliable finishing weapon, landing it for the sixth time in his last 12 fights to secure one of the biggest wins of his career.
Ulberg, known as "Black Jag," entered the contest ranked third in the light heavyweight division with a 15-1 record. The 35-year-old New Zealander, who trains out of City Kickboxing, stands six-foot-four with a 77-inch reach and posts an impressive 6.54 significant strikes per minute at 55 percent accuracy. He absorbed a knee injury during the fight but was still able to inflict enough damage to finish the bout, catching Prochazka with the same left check hook three separate times before the final stoppage.
Prochazka came in ranked second at 32-6-1, a 33-year-old Czech fighter out of Jetsaam Gym Brno. Standing six-foot-three with an 80-inch reach, the former champion lands 5.69 significant strikes per minute at 55 percent accuracy and has long been known for his unorthodox, high-volume style. That aggression, however, left him vulnerable. His inability to safely close distance proved decisive, and the pattern was familiar — he had previously been dropped twice by Pereira in a similar fashion.
Why it matters
- Ulberg's win moves him one step closer to a title shot in a division that is reshaping around him and top-ranked Magomed Ankalaev
- Ankalaev, ranked first in the division and fifth pound-for-pound at 21-2-1, represents the next logical obstacle; his wrestling base and leg-kick output could exploit Ulberg's stance and mobility
- Prochazka's second consecutive high-profile loss raises serious questions about his path back to contention at 33 years old
- The left check hook has now proven itself a repeatable, fight-ending weapon that opponents across the division will need to game-plan around
