Amir Khan taken to hospital after heavy knockout by Saul Alvarez

Amir Khan defiantly insisted he was OK while he was taken to hospital as a precaution after his heavy sixth-round knockout defeat by Saul 'Canelo' Alvarez in Las Vegas last night.

The WBC champion brutally stopped Khan with a huge right hand to make the first successful defence of his title, inflicting the fourth loss of the 29-year-old's professional career and exposing him as a natural welterweight too small to convincingly compete at the catchweight of 155lbs.
