Topuria is coming off back-to-back knockouts of featherweight greats Alexander Volkanovski and Max Holloway. Meanwhile, Oliveira (35-10 MMA, 23-10 UFC) rebounded from his split decision loss to Arman Tsarukyan at UFC 300 with a win over former Bellator champion Michael Chandler at UFC 309.

The UFC is heading for a confusing place regarding International Fight Week. The annual marquee event generally features a huge main event, and many believed that a matchup between current lightweight champion Islam Makhachev and former featherweight champion Ilia Topuria would be that matchup.

As such, Alexander Volkanovski and Diego Lopes clashed over the vacant 145lb title in April, with former champion Volk – whom Topuria dethroned last year – reclaiming his throne. Now, it is Makhachev’s vacant title that is up for grabs as Topuria faces Oliveira.
