Coach Dave Clawson said Wednesday that running back Matt Colburn has signed.
He made headlines last week, saying a Cardinals assistant told him he wouldn't accept his letter of intent on signing day. Colburn says he was asked not to enroll until January 2016 - a process known as ''grayshirting.''
Louisville coach Bobby Petrino defended the move last week, saying ''this is the one time as a college coach that you get to try to manage your roster.''
Wake Forest says Colburn will participate in preseason camp in August.
