Rob Gronkowski left confused as 'FOX NFL Sunday' crew pulls off hilarious prank: 'Whoa!'

NFL legendary tight end Rob Gronkowski was the subject of a "FOX NFL Sunday" prank that left him flabbergasted in a hilarious scene. 

Whenever it comes to breaking down tight ends, the star-studded crew is going to turn to Gronkowski, the four-time Super Bowl champion who should be wearing a gold jacket one day after being one of the best tight ends in NFL history. 

But his Fox colleagues decided to pull a fast one on him during a fake segment that everyone but "Gronk" knew wasn’t real.
