Carlos Ulberg has scored six knockouts with his left check hook in his last 12 fights, a unique achievement in UFC. Prochazka was caught by this punch three times before the knockout, failing to find a safe way to close distance despite his previous losses to Pereira from the same strike. The analysis notes that Ulberg's injured knee gave Prochazka opportunities he failed to exploit through leg kicks or takedowns. In a potential matchup with Ankalaev, the analysis gives Ankalaev a slight 55-45 edge despite Ulberg's superior speed and movement. Paulo Costa's knockout victories over Russian hand-to-hand combat specialists Kopylov and Murzakanov demonstrate his growth in distance management and fight IQ despite limited activity.
Post-UFC 327 analysis has zeroed in on Carlos Ulberg's most dangerous weapon, tracing how the New Zealand light heavyweight used his left check hook to finish Jiri Prochazka and examining what a future title matchup against Magomed Ankalaev could look like.
Ulberg, known as "Black Jag," improves to 15-1 with the victory and holds the number-three ranking at light heavyweight. The 35-year-old City Kickboxing product stands six-foot-four with a 77-inch reach and is one of the division's most prolific strikers, landing 6.54 significant strikes per minute at 55 percent accuracy. According to the post-fight breakdown, he has now scored six knockouts with the left check hook across his last 12 fights — a distinction that appears unique within the UFC.
Prochazka, ranked second at light heavyweight and now 32-6-1, walked into that same punch three times before the finish. The Czech fighter, who carries an 80-inch reach and lands 5.69 significant strikes per minute, had previously been stopped by the identical shot in his losses to Alex Pereira, yet the analysis notes he never adjusted his approach to close distance safely. The breakdown also points out that Ulberg's injured knee created openings — through leg kicks or takedown attempts — that Prochazka failed to exploit.
Looking ahead, analysts give Ankalaev a slight 55-45 edge in a potential matchup with Ulberg, crediting the Russian's overall game even while acknowledging Ulberg's superior speed and movement.
Separately, Paulo Costa draws attention in the same breakdown. The number-13-ranked middleweight, 16-4 at 35 years old, landed knockout wins over Kopylov and Murzakanov — both noted Russian hand-to-hand combat specialists. Costa lands 6.26 significant strikes per minute at 58 percent accuracy, and the analysis frames those results as evidence of genuine improvement in his distance management and fight IQ despite a relatively light recent schedule.
Why it matters
- Ulberg's check hook has now become a statistically documented pattern, making it a known threat every future opponent must game-plan around
- Prochazka's inability to adjust, despite facing the same punch before, raises questions about his path back to title contention
- A potential Ulberg-Ankalaev booking would carry direct title implications at 205 pounds
- Costa's back-to-back finishes of high-level strikers suggest a middleweight ranked higher than 13th may be warranted
