The Husker football recruiting class of 2013 added a commitment and lost a commitment on the eve of national signing day. Offensive lineman Dwayne Johnson announced he’d be attending Nebraska. Johnson is a three-star prospect from Houston, Texas. He chose the Huskers over Arkansas. On the flip-side, four-star athlete recruit Trevell Dixon changed his college choice. He’ll attend Arizona State next fall. National Signing Day is today. The Huskers will hope to finalize a class of 25 or 26 scholarship players.
