Former UFC featherweight champion Ilia Topuria will chase history as he squares off against Charles Oliveira for the vacant lightweight title in the main event of UFC 317, taking place at T-Mobile Arena in Las Vegas,

But Makhachev announced a move to welterweight and vacated the lightweight belt. Now Topuria (16-0 MMA, 8-0 UFC) meets Charles Oliveira (35-10 MMA, 23-10 UFC) for the vacant 155-pound title in the main event of UFC 317 next week at T-Mobile Arena in Las Vegas.

Topuria is set to face Charles Oliveira (35-10, 1 NC) for the vacant UFC Lightweight Championship. Islam Makhachev is the current 155-pound titleholder, but he will relinquish the gold once Topuria vs. Oliveira begins at UFC 317 on June 28.
