Ульберг describes severe knee injury after UFC 327 win over Prochazka

Carlos Ulberg has revealed the extent of a significant knee injury he suffered while defeating Jiri Prochazka at UFC 327 on April 11, describing a harrowing experience that left him unable to bear weight on the leg after the fight.

Ulberg, who competes out of the celebrated City Kickboxing gym in New Zealand, said his knee was severely swollen in the immediate aftermath and that he was struggling to stand or walk. Most alarmingly, he described a sensation of his knee slipping in and out of the joint socket during the contest itself, yet he fought through what he called unbearable pain to secure the victory.

The 35-year-old holds a 15-1-0 professional record and entered UFC 327 ranked third in the light heavyweight division. Standing six-foot-four with a 77-inch reach, "Black Jag" has built a reputation as one of the more dangerous strikers in the 205-pound class, landing 6.54 significant strikes per minute at 55 percent accuracy.

Prochazka, the Czech Republic's former light heavyweight champion, drops to 32-6-1 with the defeat. The 33-year-old stands six-foot-three with a massive 80-inch reach and had been ranked second in the division heading into the contest. He averages 5.69 significant strikes per minute at 55 percent accuracy, making Saturday's matchup a genuine clash of elite strikers.
