Rio de Janeiro erupted as Charles Oliveira reminded the world why he's one of the most dangerous submission specialists in MMA history. The former UFC lightweight champion submitted Mateusz Gamrot via rear-naked choke at 2:48 of the second round in the main event of UFC Fight Night: Oliveira vs. Gamrot, delivering a statement victory just 105 days after suffering a knockout loss to Ilia Topuria.

Main Event: Oliveira's Triumphant Return

Oliveira (36-11-0) showcased the elite Brazilian jiu-jitsu that made him a champion, dominating Gamrot (24-5-0) on the ground before securing the rear-naked choke finish. The Brazilian crowd's roar was deafening as their hero returned to form, demonstrating that his knockout loss to Topuria was merely a bump in the road rather than the beginning of a decline.

Gamrot, who stepped in on short notice, couldn't match Oliveira's ground game and was overwhelmed by the former champion's grappling pressure. The victory positions Oliveira back into title contention and proves he remains one of the division's most elite fighters.

Co-Main Event: Figueiredo Snaps Skid

In a closely contested co-main event, former flyweight champion Deiveson Figueiredo (24-4-1) secured a split decision victory over Montel Jackson (14-3-0). Two judges scored the bout 29-28 in Figueiredo's favor, while one judge awarded it to Jackson by the same margin.

Figueiredo's grappling control in the early rounds proved pivotal, as Jackson struggled to maintain consistent offensive pressure throughout the 15-minute affair. The win ended Figueiredo's two-fight losing streak and repositioned him for potential bantamweight title contention.
