Sports physician Brian Sutterer has offered a detailed medical breakdown of the serious knee injury Carlos Ulberg sustained during his light heavyweight bout against Jiri Prochazka, shedding new light on the severity of what Ulberg endured even as he came away with the victory.
Ulberg, known as "Black Jag," improved to 15-1-0 with the win, a result that carries significant weight in the 205-pound division. The 35-year-old New Zealander, who trains out of City Kickboxing, is ranked third in the light heavyweight rankings and stands six-foot-four with a 77-inch reach. He has been one of the division's more active strikers, averaging 6.54 significant strikes landed per minute at 55 percent accuracy.

Prochazka, the second-ranked light heavyweight, entered the fight at 32-6-1. The 33-year-old Czech, who competes out of Jetsaam Gym Brno, is one of the sport's most dangerous offensive fighters, landing 5.69 significant strikes per minute at the same 55 percent accuracy clip. His reach of 80 inches and height of six-foot-three make him a formidable presence in any exchange.
Sutterer's commentary focused on the mechanics of the injury itself. According to his analysis, Ulberg's shin displaced forward as a result of an ACL tear, after which visible pulsation appeared in the calf as the tibia returned to its natural position. The explanation gave fans a clearer picture of what occurred in real time during the fight.

Why it matters
- Ulberg's ACL tear is a significant injury that will likely require surgery and an extended recovery period
