UFC light heavyweight champion Carlos Ulberg suffered a significant knee injury in his title-winning fight against Jiri Prochazka at UFC 327. Despite the injury, Ulberg was able to knock out Prochazka and claim the championship. Ulberg has now undergone successful knee surgery and is expected to be sidelined until 2027, leading the UFC to potentially create an interim title in the meantime.

Why it matters

Ulberg's injury is a setback for the new champion, who had won 10 straight fights to earn the title. The UFC may need to book an interim title fight to keep the division active while Ulberg recovers, which could create an opportunity for top contenders like Magomed Ankalaev, Alex Pereira, and Jan Blachowicz.

The details

After suffering a lower-limb injury early in his fight against Prochazka, Ulberg was able to land a devastating counter left hook to knock down his opponent and finish him with ground and pound to become the new UFC light heavyweight champion. However, Ulberg suffered a significant knee injury in the process that will require surgery and keep him out of action until 2027.

  • On April 15, 2026, Ulberg defeated Prochazka to win the UFC light heavyweight title at UFC 327.
  • On April 20, 2026, Ulberg underwent successful knee surgery to repair the injury sustained in the title fight.

What they’re saying

“Knee surgery done”

— Carlos Ulberg, UFC Light Heavyweight Champion

What’s next

The UFC may create an interim light heavyweight title to be contested while Ulberg recovers from his knee surgery, with top contenders like Magomed Ankalaev, Alex Pereira, and Jan Blachowicz as potential participants.

The takeaway

Ulberg's title-winning performance at UFC 327 was marred by a significant knee injury that will sideline him for over a year. The UFC will likely need to book an interim title fight to keep the division active, providing an opportunity for other top light heavyweights to compete for championship gold in Ulberg's absence.
