UFC Rio Main Event: Charles Oliveira Vs. Mateusz Gamrot

Charles Oliveira (35-11-0-1) has been fighting with the UFC since 2010. He won the vacant lightweight title with his win over Michael Chandler in May 2021. He defended the title once, beating Dustin Poirier. He was booked to face Justin Gaethje in his second title defense, but Oliveira missed weight for that fight, which he won by submission, losing the title on the scale.

Oliveira had a chance to regain the belt in October 2022, but Islam Makhachev submitted him and claimed the vacant belt. Since that loss, Oliveira is 2-3, beating Beneil Dariush by TKO in June 2023, losing to Arman Tsarukyan via split decision in April of this year and then defeating Chandler in November 2024.

In his most recent outing, Oliveira fought Ilia Topuria for the vacant UFC 155-pound title. Topuria won that contest via first-round knockout.

Oliveira is the No. 4 fighter in the official UFC lightweight rankings.

Mateusz Gamrot (25-3-0-1) has been with the UFC since 2020, when he signed with the promotion after winning and defending the KSW lightweight title. The UFC initially had Gamrot as a late replacement for Renato Moicano against Magomed Mustafaev, but Gamrot faced fellow UFC newcomer on that UFC Fight Night card. The two won “Fight of the Night” honors, with Mustafaev winning the bout by split decision.

Gamrot bounced back from that loss, the first of his career, with four straight UFC wins. He picked up stoppages over Scott Holtzman, Jeremy Stephens, Carlos Diego Ferreira, and a decision over Arman Tsarukyan during that stretch, earning three fight-night bonus awards, and the No. 9 lightweight ranking.

Gamrot’s winning streak ended in October 2022 when the No. 6 ranked Beneil Dariush defeated him by unanimous decision on the UFC 280 pay-per-view card.

Since that loss, Gamrot is 4-1 with three decisions and one TKO victory. He had a three-fight winning streak heading into UFC 305, but lost to Dan Hooker in a Fight of the Night decision.

Gamrot bounced back from that setback with a May decision win in a three-round matchup opposite Ľudovít Klein.

Gamrot is the No. 8 ranked UFC 155-pounder.
