Earl I think Khan let's the fight go 4 rounds atleast..5-7 rounds is your bet EDIT: Roach said Khan will knock him out in the 4'th. I'm going to do single rounds 3 and 4 for backup!
McCloskey is undefeated, is the European Champion and has beaten some decent fighters. He has a 55% KO ratio at 140lbs. His points wins have been pretty wide and he has stopped his last four inside the distance, five if you count Colin Lynes. So basically he's performing pretty well at British, Commonwealth and European level. He's pretty big, appears durable and has good experience. Based on this, I'm not writing him off just yet. I can see Khan looking flashy and looking for the knockout, he may make McCloskey look very ordinary, however, IF (and it's a big if) McCloskey can tag Khan then the fight could change if Khan decides to trade a little more once he gets hit. Will McCloskey take the fight to Khan? Or will he look to counter him? You need to pressure Khan and force mistakes, McCloskey has enough power to drop Khan, perhaps he has the skills, stamina and toughness to make the fight competitive too.
