Ex-NFL star James Harrison says there's no need for a stunt double on set of his new wrestling TV show ... revealing he does his ALL his own moves -- and it hurts!!!
As we previously reported, the former Pittsburgh Steelers linebacker is taking his talents from the gridiron to the screen ... kickstarting a career in acting after 15 years in the NFL.
Harrison plays a journeyman wrestler named Apocalypse in the new Starz show, "Heels" ... which is about 2 brothers going to war with their rivals over their father's wrestling promotion in a small Georgia town.
