The eagerly-anticipated clash will see a new UFC men’s lightweight champion crowned after Islam Makhachev announced his decision to vacate the title last month in order to jump up to welterweight for an intended shot at new champion Jack Della Maddalena.
Topuria knows all about relinquishing belts to move up a division in search of a second, having let go of the featherweight gold earlier this year in order to move to 155 pounds and attempt to become just the 10th person in UFC history to win world titles in two different weight classes.
The formidable ‘El Matador’ remains undefeated in his 16-bout professional MMA career so far and in eight fights with the UFC, where he is currently ranked third on the pound-for-pound list, behind only Makhachev and dominant bantamweight champion Merab Dvalishvili.
Oliveira is no2 in the lightweight rankings after beating Michael Chandler again at UFC 309 in November, bouncing back from his loss to Arman Tsarukyan having seen a first attempt to regain the lightweight championship foiled by Makhachev in Abu Dhabi in 2022.
The Brazilian submission specialist had initially won the vacant title by knocking out Chandler in 2021 following the retirement of Khabib Nurmagomedov, successfully defending against Dustin Poirier before being stripped for missing weight ahead of his win over Justin Gaethje at UFC 274.
The co-main event of the night at the T-Mobile Arena in Las Vegas will see Oliveira’s compatriot Alexandre Pantoja defend the UFC men’s flyweight title for the fourth time against Kai Kara-France of New Zealand.
