"It was an amazing experience," the former Pittsburgh Steelers said. "Just being in makeup preparing me for my role was cool. I actually scared myself when I looked in the mirror for the first time after."
Ward played football at University of Georgia with former "The Walking Dead" star, IronE Singleton, who played "T-Dog," Pittsburgh Post-Gazette reported Sunday.
"A former Georgia teammate of mine is one of the stars of the show, and my agent thought it would be something fun and different for me to do," Ward said.
"The Walking Dead," which is in the middle of its third season, comes back from its winter break Feb. 10.
