UFC on ESPN: Gamrot vs. Klein—also identified as UFC on ESPN 68 and UFC Vegas 107'—was a mixed martial arts competition organized by the Ultimate Fighting Championship on May 31, 2025, hosted at the UFC Apex located in Enterprise, Nevada, United States.
Background
Initially, the event was to be headlined by a women's flyweight clash featuring Erin Blanchfield and Maycee Barber. This matchup had previously been arranged for UFC 269 in December 2021, but Barber withdrew at that time. During the weigh-ins for this event, Barber exceeded the weight limit by 0.5 pounds and consequently forfeited 20% of her fight purse. Shortly before fighters were set to enter the octagon, Barber pulled out due to experiencing a seizure. As a result, a lightweight contest between former KSW Featherweight and Lightweight Champion Mateusz Gamrot and Ľudovít Klein was elevated to serve as the main event.
A flyweight encounter between Allan Nascimento and Jafel Filho, which had been postponed previously because of Nascimento's illness, took place at catchweight after Nascimento weighed 1.5 pounds over the limit; he was fined 20% of his earnings.
The card also included a women's strawweight bout featuring former Invicta FC Atomweight Champion Rayanne dos Santos against Alice Ardelean. This fight was originally scheduled for October 2024 but was postponed when dos Santos withdrew due to a broken arm.
After several reschedulings, a women's featherweight matchup between Ketlen Vieira and The Ultimate Fighter: Heavy Hitters victor Macy Chiasson took place. Initially planned as a bantamweight contest, it was changed to featherweight on weigh-in day because Vieira encountered difficulties making weight; she relinquished 25% of her purse as a penalty.
A welterweight bout featuring Jeremiah Wells and debutant Andreas Gustafsson was arranged but later canceled after Wells suffered an injury and his replacement Trevin Giles sustained a head injury during weigh-ins. Gustafsson was subsequently rebooked for the next week's event at UFC 316.
Two additional welterweight fights were scheduled: Ramiz Brahimaj versus Oban Elliott and Billy Ray Goff against newcomer Ko Seok-hyun. Due to visa complications, Elliott and Ko were unable to compete; consequently, Brahimaj faced Goff instead. Elliott and Ko were rescheduled to meet three weeks later at UFC on ABC: Hill vs. Rountree Jr..
A lightweight contest between MarQuel Mederos and Bolaji Oki was announced but Mederos withdrew three days before the event due to illness. Promotional newcomer Michael Aswell stepped in as his replacement.
