Carlos Ulberg has revealed the extent of a serious knee injury he sustained during his victory over Jiri Prochazka, disclosing that the joint was swollen, partially dislocating during the fight, and left him unable to bear weight on the leg.
The 35-year-old New Zealander, who trains out of City Kickboxing, described an excruciating experience in which his knee repeatedly shifted in and out of the socket while he competed. Despite being unable to put weight on the leg and battling unbearable pain throughout the bout, Ulberg pushed through to earn the win. He has since reported significant swelling and difficulty standing, moving only slowly as a result of the damage.
Ulberg, known as "Black Jag," holds a 15-1-0 professional record and is currently ranked third in the UFC light heavyweight division. Standing six-foot-four with a 77-inch reach, he is one of the division's most physically imposing strikers. His output numbers reflect that — he lands an impressive 6.54 significant strikes per minute at a 55 percent accuracy rate, figures that rank among the best in the weight class.
Why it matters
- Ulberg's win over Prochazka significantly strengthens his position as a light heavyweight title contender, but the knee injury now casts serious doubt on his timeline for a potential next fight.
- The severity of the injury — possible ligament or structural damage based on his description of joint instability — could require surgery and an extended layoff.
- A prolonged absence may affect divisional rankings movement and reshape the contender picture at 205 pounds.
