Overview

• The UFC officially confirmed the Oct. 11 lightweight main event at Rio’s Farmasi Arena will feature No. 4-ranked Charles Oliveira vs. No. 10-ranked Rafael Fiziev.
• Oliveira accepted the Fight Night headliner just 105 days after his first-round knockout loss to Ilia Topuria and will make his first home-country appearance since 2020.
• Fiziev snapped a three-fight skid in June with a unanimous decision win over Ignacio Bahamondes and aims to break into the lightweight top five.
• Both fighters see the bout as a springboard toward another title opportunity in a division reshaped by recent championship changes.
• The return of UFC to Rio underscores the promotion’s focus on its Brazilian market and the growing depth of the lightweight roster.
