Carlos Ulberg entered the Kaseya Center in Miami on April 11, 2026, largely considered an underdog by bookmakers. However, he left as the UFC Light Heavyweight Champion, astonishingly achieving this feat while fighting on a single functioning leg.
Initially, the betting lines favored Jiří Procházka, opening as a -142 favorite with Ulberg at +120 for the vacant 205-pound title. This pricing seemed logical given Procházka’s impressive 2025 record, which included consecutive knockout victories over Jamahal Hill and Khalil Rountree Jr. His only UFC loss had been to Alex Pereira, who had since moved up to heavyweight.
As UFC 327 approached, the odds saw a significant shift. By the time the main card began, the gap between the fighters had narrowed considerably. Procházka was listed at -118 and Ulberg at -102, indicating a much closer contest. Some platforms even had Procházka at -120 and Ulberg at +100 on April 10. In European decimal odds, Procházka was at 1.83 and Ulberg at 2.00, implying a roughly 56.3% chance of victory for Procházka and 47.6% for Ulberg.
Procházka’s credentials were well-established. He had won the UFC light heavyweight title in June 2022 and boasted a career with 23 first-round finishes, never having gone to a decision in the UFC. His two defeats came only against Alex Pereira, both by second-round TKO. Entering UFC 327, he was widely regarded as the most dangerous finisher in the division after his two dominant wins in 2025.
On the other hand, Ulberg was on a nine-fight winning streak but had not previously competed for a UFC title. His sole UFC loss was a second-round knockout to Kennedy Nzechukwu in March 2021. Since that setback, he had secured victories over notable opponents such as Jan Błachowicz and Volkan Oezdemir via decision, and a rapid 12-second knockout against Alonzo Menifield, one of the fastest in light heavyweight history. He also had a recent win over Dominick Reyes. Despite his impressive streak, some analysts questioned whether he had faced the same caliber of competition as a multi-time title contender like Procházka.
The fight took a dramatic turn for Ulberg very early on. In the opening minute, his right knee buckled as he stepped back, causing him to slip. Replays suggested the injury resulted from an awkward landing rather than a direct impact. UFC President Dana White later indicated to reporters that the injury could be an ACL tear, though a formal diagnosis was pending.
Recognizing Ulberg’s apparent injury, Procházka began targeting his legs with repeated low kicks, aiming to exploit his compromised mobility. Ulberg struggled to maintain his balance, repeatedly leaning on the cage. The fight appeared to be heading towards a stoppage in Procházka’s favor, with odds before the bout favoring under 2.5 rounds at -115, a prediction that seemed increasingly likely.
However, in a moment of sheer will and skill, Ulberg steadied himself against the cage, patiently waited for an opening, and landed a precise counter left hook that instantly knocked Procházka out. He followed up with ground strikes, leading to the referee waving off the fight at 3:45 of the first round.
This victory extended Ulberg’s winning streak to ten consecutive fights within the UFC. He became the 19th undisputed UFC light heavyweight champion and joined fellow City Kickboxing fighters Israel Adesanya and Alexander Volkanovski as UFC titleholders. Despite being a slight underdog and suffering a significant injury within the first minute, Ulberg persevered and secured the championship title.
