Charles Oliveira has opened as a massive betting underdog against Ilia Topuria.
Islam Makhachev vacated his lightweight title and moved up to welterweight to challenge Jack Della Maddalena after the Australian dethroned his friend Belal Muhammad at UFC 315. Makhachev would have defended his lightweight title against Ilia Topuria had Muhammad retained his belt.
However, Topuria (16-0) will now fight former champ Charles Oliveira (35-10) for the vacant 155-pound title in the UFC 317 main event on June 28 at T-Mobile Arena in Las Vegas.
