This one kind of throws a wrench into the welterweight division. According to MMAJunkie.com, Mike Swick got a concussion while training for his UFC 103 contender fight against Martin Kampmann. He has pulled out of the fight and will be replaced by UK stand-out Paul Daley. Swick versus Kampmann was already questionable to determine the next to fight for the welterweight belt, but Kampmann versus Daley, a fighter who has demonstrated a lack of a ground game, is even less appealing. Daley always has a chance to knock Kampmann out, but chances are this will be a showcase for Kampmann before he gets a title shot. The welterweight division is looking pretty thin now that GSP has embarassed all of the top fighters.
