Thanks to Islam Makhachev's impending move to the welterweight division, Ilia Topuria and Charles Oliveira will meet for the richest prize at 155 pounds. This UFC lightweight championship bout scheduled for five rounds is taking place Saturday, June 28 at T-Mobile Arena in Las Vegas.

After it was announced that Makhachev would relinquish the lightweight title in pursuit of winning a welterweight championship, the UFC obliged Topuria's request to move up – only after he, too, relinquished his featherweight belt – and booked him in an immediate vacant title bout against former champion Oliveira.

Topuria, 28, is coming off a 2024 in which he was named MMA Junkie's Male Fighter of the Year after he knocked out Alexander Volkanovski to claim the 145-pound title and most recently knocked out Max Holloway in his lone title defense last October.

Oliveira, 35, is 2-2 since he was stripped of the title after missing weight for his bout against Justin Gaethje in May 2022. Oliveira went on to submit Gaethje but has since alternated losses (vs. Makhachev and Arman Tsarukyan) and wins (vs. Beneil Dariush and Michael Chandler) since then.

Here are the walkout times for the UFC 317 main event between Topuria and Oliveira.
