Even a roided to the gills Amir Khan, got man handled and had his **** pushed in by the walking cadaver of Kell Brook. So he managed to retire both in shame and an utter disgrace. A mere con indeed.
I was just coming to post this, roused to the gills and he still got beaten the **** out of by Brook!
Can't say I'm surprised, known for cheating on his wife, done more than once for dangerous driving, doesn't really seem the type to follow the rules, so him cheating by using PED's isn't a stretch of the imagination.
