Paralyzed from the neck down during a 2012 game, Tulane's Devon Walker has remained a large part of the Green Wave's football program, and the university itself.
Prior to Thursday's season opener, the school showed its respect for Walker by retiring his No. 18 across its entire athletic program.
While the football program had previously highlighted his No. 18 at Yulman Stadium, and on a flag that a player carries out of the tunnel prior to games, Thursday's gesture took things to another level.
"I don't have the words to describe it," Walker told The Athletic.
