Since retiring, Pittsburgh Steelers legend Hines Ward has kept busy as a studio analyst for NBC’s “Football Night in America.”
He also has spent some time as a corpse risen from his grave.
Thanks to the connections of a college teammate who now acts on “The Walking Dead,” Ward will appear in a future episode of AMC’s hit show about zombies. He will be a zombie extra, and as the picture above shows, some magic was performed with his make up.
It worked so well that Ward even scared himself:
“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 told the Pittsburgh Post-Gazette.
