It was a heavyweight fight that captivated the whole sporting world.
And on Saturday night, one lucky YouTuber managed to sneak his way into the heart of it - amazingly inside the ring during the aftermath of Anthony Joshua's unification title bout with New Zealand's Joseph Parker in Cardiff.
Following 12 hard-fought rounds, Joshua was awarded the victory by a unanimous points decision and now holds the WBA, IBF and WBO belts after defeating Parker.
It was also a night to remember for YouTube prankster Zac Alsop.
The video-maker released his footage on Monday where he revealed exactly how he plotted and carried out the audacious bid to get involved in proceedings at the Principality.
Alsop set up a video diary of his day, detailing how he managed to forge a security pass for one of the biggest night's in British sport - and just how easy it was for him to gain access.
Alsop then filmed himself dodging security and maneuvering his way throughout various sections of the Principality Stadium concourse and seating - including the press area, before he eventually found his way to ringside with his home-made pass put together by himself.
Having made it ringside for the pre-fight walk-on's - pointing out that he had the same ID on as promoter Eddie Hearn - Alsop settled down to watch the highly-anticipated bout, which somewhat failed to live up to expectation.
After the fight had concluded, Alsop made his move to step inside the ring, finding himself just a few metres away from World Champion Brit, Joshua and his entourage of bodyguards, Television crews and his backroom team.
If you are wondering how on earth did he pull off this stunt once? Well, he's done a similar thing before!
Back last summer, ahead of the one-off boxing bout between Conor McGregor and Floyd Mayweather Jr, he made it into the pre-fight press conference in London.
But some serious questions have got to be asked how he keeps getting away with it...News Now - Sport News
