UFC Fight Night: Oliveira vs. Gamrot—also identified as UFC Fight Night 261 and UFC on ESPN+ 119'—was a mixed martial arts event organized by the Ultimate Fighting Championship on October 11, 2025, hosted at the Farmasi Arena in Rio de Janeiro, Brazil.
Background
This event represented the UFC's 13th occasion hosting a fight card in Rio de Janeiro, marking their return since UFC 301 held in May 2024, and their first Fight Night event in the city since May 2015.
The initial headliner was set to be a lightweight clash between former UFC Lightweight Champion Charles Oliveira and Rafael Fiziev. However, Fiziev withdrew because of a knee injury, leading to the inclusion of former KSW Featherweight and Lightweight titleholder Mateusz Gamrot as his replacement.
A heavyweight contest featuring former LFA Light Heavyweight Champion Ryan Spann against Valter Walker was planned but ultimately did not take place; Walker was subsequently scheduled to face Mohammed Usman, who pulled out two days prior to the event, resulting in the cancellation of that fight.
In the welterweight division, a bout between Santiago Ponzinibbio and Vicente Luque was arranged; however, Ponzinibbio's injury led to Joel Álvarez stepping in as his substitute.
Additionally, a welterweight matchup involving former LFA Welterweight Champion Gabriel Bonfim and Randy Brown was rescheduled to headline UFC Fight Night: Bonfim vs. Brown.
During the weigh-ins, Saimon Oliveira exceeded the bantamweight limit by eight pounds; consequently, his fight proceeded at catchweight with a financial penalty imposed and paid to his opponent Luan Lacerda.

Monetary bonuses of $50,000 were granted to the following fighters:
- Fight of the Night: No award was given.
