Last winter, Peyton Manning caught the media off guard when he started working out in Durham with David Cutcliffe, his college quarterbacks coach. Manning, still with the Colts at the time, had missed the entire 2011 season after having neck surgery, and his future playing football was in doubt. He made several trips to Duke, and, under Cutcliffe's tutelage, began to return to his old form. He successfully made the transition back under center for the Denver Broncos, who host the Baltimore Ravens in an NFL playoff game Saturday.

Before Manning takes the field, the NFL Network will show a documentary focusing on his rehab work with Cutcliffe at noon. Click here to see a preview, and set your DVRs.
