North Carolina coach Bill Belichick is turning to senior quarterback Max Johnson to start Saturday's game against Clemson, a source told ESPN. Gio Lopez, who opened the season as the Tar Heels starter, is a game-time decision because of a lower body injury, but if he is available, he will serve as Johnson's backup, the source said. Johnson replaced the injured Lopez two weeks ago during a 34-9 loss to UCF.
