Former champion Cook was floored three times in the opening session by Scotsman Burns and failed to recover from a back injury sustained in the first knockdown, after a right hook to the body. Cook looked in agony as he tried to stand up straight and fight on. But after it was clear that the Londoner was in no fit state to continue, his corner threw in the towel.
A devastated Cook was taken out of the ring on a stretcher, (right) but it was unclear whether the injury was inflicted by the shot or by Cook’s attempt to slip Burns’ shots had seen him away from the blow.
