Khan fails to convince in narrow win

Amir Khan clambered up off the canvas to keep his dreams of muscling back in on the world title picture just about alive with a dramatic points victory over Julio Diaz at the Motorpoint Arena in Sheffield tonight.

Khan turned a routine-looking assignment into a desperate war as he was dumped by a big left hook in the fourth round and teetered on the brink of further knockdowns as Diaz forced a spectacular finish.
