Don't really think it will happen, if so not anytime soon..
Think they will put khan in against some better know fighters, need to build him up to a level again and get some proof behind the glitz etc, as i follow boxing and he hasn't really been in with any well know fighters... Prescott is a fair fighter (from what little i've seen) but everyone said He was a big step up for Khan.. to be honest i had never heard of him before that fight!
He is fighting on the 6th Dec in london, on Nicky cooks WBO title defence undercard (not as the main event. pay per view rubbish.. thank god), don't know who against though..
