The UFC has finally booked Ilia Topuria's highly anticipated lightweight debut – and it will be for another title. Topuria, who vacated the featherweight championship in February, is scheduled to take on former UFC lightweight champ Charles Oliveira at UFC 317 on June 28 from T-Mobile Arena in Las Vegas.

Islam Makhachev has vacated his lightweight belt and will move up to the welterweight division to fight Jack Della Maddalena, Dana White announced Tuesday.

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.
