With 10 wins in a row and the UFC’s interim lightweight title, Tony Ferguson has become one of the most feared 155-pounders in the world. In a month at UFC 223, Ferguson (23-3 MMA, 13-1 UFC) wil take on another one of them in Khabib Nurmagomedov (25-0 MMA, 9-0 UFC), and the winner will become the UFC’s undisputed lightweight champ. (There’s a presumptive stripping of Conor McGregor’s title that will take place once the fight begins, UFC President Dana White has said.) Nurmagomedov has never lost.
