Four Notre Dame football players have been held out of team activities during an internal investigation into academic fraud. Notre Dame Athletics Director Jack Swarbrick says Coach Brian Kelly was hit hard by the news. ESPN college football insider Brett McMurphy says it's difficult to envision the players returning to the football field for the Irish. Kelly says if the players don't return it will be difficult to overcome. Notre Dame coach Brian Kelly admits he needs to do a better job of creating an environment in which players know they are accountable.
