The main event serves as a pivotal clash for the lightweight division. Former champion Charles Oliveira looks to avoid his first two-fight losing skid in nine years after a recent title fight knockout at the hands of current lightweight champion and superstar Ilia Topuria.

Facing him is Mateusz Gamrot, who brings a high-level grappling base and has the opportunity to score the most significant win of his career, having won four of his last five fights. Gamrot accepted the fight on just 10 days' notice after the original headliner, Rafael Fiziev, withdrew due to a knee injury.

The co-main event will be a bantamweight contender clash between Deiveson Figueiredo and Montel Jackson.

After a rough stint of getting decisively outstruck by Petr Yan and getting finished by Cory Sandhagen by an unusual leg lock, the former flyweight champion Figueiredo aims to halt the first losing streak of his career by beating Jackson. Jackson, on the other hand, is a surging contender in the division. He is currently riding a six-fight winning streak and hasn't lost in over five years.

This storied tradition of Brazilian MMA culminates with UFC Fight Night 261, as the Farmasi Arena in Rio prepares for another electrifying night of fights headlined by Charles Oliveira and filled to the brim with local Brazilian talent.
