Former featherweight champion  Ilia Topuria relinquished the 145-pound title and moved up to the lightweight division to compete for the undisputed 155-pound crown against former champion  Charles Oliveira at UFC 317 last June.  He knocked out “do Bronxs” in the first round to capture the lightweight title. Who “El Matador” will face in his first title defense remains unclear, but rival and No.
