Ulberg, known as "Black Jag," is ranked third in the light heavyweight division and carries a 15-1-0 professional record. The 35-year-old New Zealander, who trains out of City Kickboxing, stands six-foot-four with a 77-inch reach and has been one of the more active strikers in the division, averaging 6.54 significant strikes landed per minute at 55 percent accuracy. His bout with Prochazka represented one of the biggest tests of his career to date.
In his update, Ulberg described a harrowing experience during the fight itself, saying he could feel his knee moving in and out of the joint while competing. Afterward, he reported severe swelling and an inability to stand or walk normally, with the pain described as unbearable when attempting to put weight on the leg. No official diagnosis or recovery timeline has been disclosed.
Prochazka, the Czech Republic's ranked second light heavyweight, enters the record books at 32-6-1. The 33-year-old orthodox striker from Jetsaam Gym Brno is listed at six-foot-three with an 80-inch reach and averages 5.69 significant strikes per minute at 55 percent accuracy — making for a closely matched striking contest on paper against Ulberg.
