Ilia Topuria went off on Islam Makhachev for moving up to welterweight instead of fighting him.
Before Makhachev (27-1 MMA, 16-1 UFC) vacated his UFC lightweight title, he dismissed ex-featherweight champ Topuria (16-0 MMA, 8-0 UFC) as his next title challenger. He wasn't interested in defending his belt against another 145-pounder coming up a weight class after two of his four lightweight title defenses coming over Alexander Volkanovski.
Makhachev has always wanted to become a two-weight division UFC champion, but with his friend Belal Muhammad holding the welterweight title, he held off his aspirations. Now that Muhammad lost his welterweight belt to Jack Della Maddalena at UFC 315, Makhachev has relinquished his lightweight belt to challenge Della Maddalena.
