A vacant lightweight title fight between former champion, Charles Oliveira, and former featherweight titleholder, Ilia Topuria is set to take main event honors at UFC 317 at the end of next month during International Fight Week, as confirmed by the promotion tonight.
Oliveira, the current number two ranked lightweight contender, has been sidelined since last November, where he lodged his second career win over former title challenger, Michael Chandler in a five round unanimous decision win at Madison Square Garden in the co-main event of UFC 309.
And vacating his featherweight strap earlier this annum, Spanish finisher, Topuria confirmed his intention to fight at the lightweight limit — having become the first to knock out, Max Holloway in their UFC 308 title fight at 145lbs in October of last year.
