Josh Warrington was taken to hospital after suffering a suspected fractured jaw and broken hand in his world title victory over Kiko Martinez.
Warrington dominated the Spanish champion from the first bell, dropping him in the opening round before the fight was stopped in the seventh. In winning back the belt, Warrington becomes a two-time champion having relinquished the title 15 months ago.
He went on to be brutally knocked out by Mauricio Lara before their rematch was halted in the second round with the Mexican badly cut. He was handed a surprise shot at redemption when Martinez KO'd Kiko Galahad last November and opted to defend his belt against Warrington.
