Cardinals' Barkley leaves too little to the imagination in pregame outfit

Fans of the Arizona Cardinals had their worst fears realized Sunday -- not against the Seattle Seahawks but rather before the game, when third-string quarterback Matt Barkley took the field before warm-ups. 

Barkley was the biggest loser in the Cardinals' weekly Quarterback Challenge and emerged at Arizona's University of Phoenix Stadium in a skin-tight outfit that was tame in comparison to the silver hula skirt and bra worn by starter Carson Palmer a week ago.

Barkley -- wearing UGG boots with way-too-tight shorts and a cut-off shirt -- bared a bit too much skin for even the most ardent Cardinals followers.
