Carlos Ulberg has secured six knockouts with his left check hook in his last 12 fights, a weapon that proved decisive against Jiri Prochazka at UFC 327. The analyst notes Ulberg caught Prochazka with the punch three times before the knockout, despite Prochazka having been dropped by the same strike twice previously in fights with Alex Pereira. Ulberg has successfully landed the punch against both orthodox and southpaw opponents throughout his recent run. The post questions whether Magomed Ankalaev can avoid the same fate, noting that Thiago Santos previously hurt Ankalaev twice with the same punch. While Ulberg showed vulnerability when his knee was damaged during the fight, his superior movement and timing allowed him to finish Prochazka. The analyst favors Ankalaev 55-45 in a potential matchup based on Ankalaev's ability to mix in wrestling and maintain pressure.
Carlos Ulberg delivered a stunning light heavyweight statement at UFC 327 on April 11, stopping Jiri Prochazka via knockout with the left check hook that has become the defining weapon of his recent career.
Ulberg, nicknamed "Black Jag," improved to 15-1 and holds the number-three ranking at light heavyweight. The 35-year-old New Zealander out of City Kickboxing stands six-foot-four with a 77-inch reach and lands an impressive 6.54 significant strikes per minute at 55 percent accuracy. According to post-fight analysis, the left check hook has now produced six knockouts across his last 12 fights, with Ulberg landing the shot three times before it ended Prochazka's night. Notably, he has connected with the punch against both orthodox and southpaw opponents during that run, demonstrating its versatility as a weapon. The fight also revealed some vulnerability, as Ulberg's movement was hampered after suffering knee damage, yet his timing and footwork proved sufficient to put Prochazka away.
Prochazka, the 33-year-old Czech ranked second at light heavyweight, falls to 32-6-1. The six-foot-three orthodox fighter carries an aggressive output of 5.69 significant strikes per minute, but analysis noted he had been dropped by the same left check hook twice previously in his fights with Alex Pereira, a pattern Ulberg exploited on the night.
Why it matters
- Ulberg's win over the number-two ranked Prochazka positions him as a credible title contender at 205 pounds
- The left check hook has now proven effective against elite-level opposition, raising questions about how the division's top fighters will game-plan around it
- Number-one ranked Magomed Ankalaev of Russia sits at 21-2-1 and carries a pound-for-pound ranking of fifth; analysts note Thiago Santos previously hurt Ankalaev twice with the same punch, though Ankalaev's wrestling — 0.79 takedowns per 15 minutes — and pressure style may offer a different tactical challenge for Ulberg
