Light heavyweight champion Carlos Ulberg has undergone surgery after sustaining a serious knee injury during his victory over Jirí Prochazka at UFC 327 in Miami last weekend. The New Zealander suffered a torn ACL in his right knee during the opening round of the contest.
Despite the injury affecting his movement early in the fight, Ulberg continued and secured a knockout win to retain the title. The result extended his professional record to 14-1 and marked a significant moment in the light heavyweight division.
Ulberg travelled to Las Vegas shortly after the bout, where he underwent a successful procedure earlier this week. His manager later confirmed that medical scans had revealed a complete ACL rupture, ruling him out for an extended period.
The champion has since shared updates from his recovery on social media, indicating the start of rehabilitation. No timeline has been provided for his return to competition.
The injury raises questions about the immediate future of the light heavyweight title, with the Ultimate Fighting Championship yet to confirm how the division will proceed during Ulberg’s absence. The weight class has seen multiple disruptions in recent years due to injuries and changes in divisions.
Former champions Jamahal Hill and Prochazka both vacated the belt in previous seasons following injuries, while Alex Pereira recently moved up a division.
Prochazka, who was defeated in the bout, acknowledged the impact of the injury and later expressed interest in a rematch once Ulberg returns to full fitness.
