It was long-rumored that 74-year-old Vince McMahon personally jumped off a 10-foot platform before WrestleMania 36 to ease Rob Gronkowski's fears ...
Turns out, IT'S TRUE -- AND THE WHOLE THING WAS CAPTURED ON VIDEO!!!
The whole incident was captured by "WWE 24: WrestleMania: The Show Must Go On" [h/t ProWrestlingSheet] -- which shows everything that happened behind WWE's biggest event of the year.
Remember, the event was taped on March 25 and 26 -- and aired on April 5 and 6 -- featuring Gronk serving as the "host" of the 2-day PPV event.
One of the big 'Mania moments featured Gronk jumping from the platform -- but before that happened, Vince McMahon personally walked the NFL star through the stunt.
Again, VINCE IS 74 YEARS OLD AND THREW HIMSELF OFF A PLATFORM!!!
No sweat for Vince! Gronk noted that the stunt was more like a "trust fall" with spotters.
In the end, Gronk executed his jump perfectly -- winning the WWE 24/7 title in the process!!
A bunch of WWE stars weighed in on Vince's role in the Gronk stunt -- and to say they were impressed is an understatement!
