Ex-NFL punter Pat McAfee learned the hard way ... WRESTLING HURTS!
McAfee was hosting his WWE Watch Along show for the 'Extreme Rules' pay-per-view -- when he invited WWE legend Matt Hardy to demonstrate a Kendo stick attack on his back.
Hardy reached back and delivered an EPIC shot on Pat's back -- creating one of the most painful sounds we've ever heard -- and leaving one hell of a black and blue mark!!
The entire room erupted ... as Pat tried to cope with the pain. It's insane.
Bottom line ... it may be scripted, but it ain't fake.
By the way, McAfee was a pretty solid punter in the NFL -- he was a 2-time Pro Bowler and was a 1st-team All-Pro in 2014.
He was selected by the Indianapolis Colts in the 7th-round of the 2009 NFL Draft -- and played until 2016, when he retired (partially due to knee injuries).
Feel better, bro.
