**Oliveira Now Faces Gamrot at UFC Rio After Fiziev Injury**
**Rio de Janeiro, Brazil** – Former UFC Lightweight Champion Charles “Do Bronx” Oliveira will now face Mateusz Gamrot in the main event of UFC Fight Night in Rio de Janeiro on October 11th, officials announced Tuesday. The bout replaces Oliveira’s originally scheduled fight against Rafael Fiziev, who withdrew last week due to an injury.
The fight marks a homecoming for Oliveira (35-11), who hasn’t competed in Brazil since March 2020. The UFC scrambled to find a replacement after Fiziev’s withdrawal, and Gamrot (25-3) quickly stepped up, publicly calling for the fight.
Gamrot, currently ranked No. 8 in the lightweight division, has won four of his last five fights, with his only defeat coming to Dan Hooker in August. He boasts impressive victories over Rafael dos Anjos, the injured Fiziev, and Arman Tsarukyan.
Oliveira, ranked No. 4, is looking to rebound after suffering a knockout loss to Ilia Topuria in July’s vacant title fight. A victory against Gamrot would put Oliveira back into title contention.
The UFC Fight Night event will take place at Farmasi Arena in Rio de Janeiro. Fight fans can expect a exciting match between these two top-ranked lightweights.
