Hines Ward may be full of life, but he didn't appear that way on Sunday.
With his eyebrows completely gone, and bloody gashes and scars covering his face, the football star and former Dancing with the Stars champ
, 36, looked unrecognizable guest-starring on AMC's The Walking Dead
"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 told the Pittsburgh Post-Gazette
, of guest starring on the show where his pal, IronE Singleton played fan favorite T-Dog.
"It was an amazing experience. 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 is also featured in a before-and-after
set of pictures that shows 11 different people looking like their normal selves and then looking like deceased zombies, pegged to Sunday's episode.
