Carlos Ulberg knocks out Jiri Prochazka in first round at UFC 327

Carlos Ulberg delivered a stunning first-round knockout of Jiri Prochazka at UFC 327 on April 11, sending shockwaves through the light heavyweight division and announcing himself as a serious title contender at 205 pounds.

Ulberg, known as "Black Jag," entered the bout ranked third in the light heavyweight division with a record of 15-1-0. The 35-year-old New Zealander, who trains out of City Kickboxing, stands six-foot-four at 193 cm with a 77-inch reach. His striking output has been a consistent weapon throughout his UFC run, averaging 6.54 significant strikes landed per minute at 55 percent accuracy — numbers that reflect a pressure fighter with genuine finishing power.

Prochazka came in ranked second in the division, carrying a record of 32-6-1 and the pedigree of a former light heavyweight champion. The 33-year-old Czech standout from Jetsaam Gym Brno is an aggressive, high-volume striker in his own right, averaging 5.69 significant strikes per minute at 55 percent accuracy. At six-foot-three with an extraordinary 80-inch reach of 203 cm, Prochazka has the physical tools to threaten anyone in the division. The loss, however, represents another significant setback in what has become a turbulent chapter of his career.
