Devon Walker, a former safety for the Tulane Green Wave was injured on September 8, 2012, when Walker collided head-on with one of his own linemen as they both went in for a tackle. The injury left him paralyzed from the neck down. Without the use of his hands, Walker now wears special glasses that allow him to type notes with his eyes. He moves his wheelchair using a series of sips and puffs of air through this white straw. A tracheotomy tube helps Walker breathe: His voice isn’t quite as strong as it once was, despite multiple procedures aiming to bolster his breathing and speaking.
