Surfer and combat sports enthusiast Mark Zuckerberg accused of cheating and throwing tantrum in wild showdown at debut jiujitsu contest!

“You take some head blows along the way!”

The fight world was cock-a-hoop yesterday following Mark Zuckerberg’s domination of a jiujitsu contest where the Facebook founder and part-owner of Instagram won gold and silver medals competing in the Gi and non-Gi divisions.

A who’s who of the fight world were quick to dive onto Zuck’s snorkel, including UFC champs Brandon Moreno, Alex Volkanovski and Izzy Adesanya.

It was a long way from his hard-core big-wave sessions on Maui with one-time BFF Kai Lenny that had become so full-on they tested, he said, his very mortality.

“I do a fair amount of, like, extreme sport type stuff so I’m definitely aware of (my mortality),” Zuck told podcaster Lex Friedman. “I train hard. So if I’m gonna go out in a 15-foot wave then I’ll make sure we have the right safety gear, make sure I’m used to that spot and all that stuff…(But) you take some head blows along the way.”

After an almost uniformly positive response to his success on the mat yesterday, the billionaire following fellow celebrity Tom Hardy into the competitive jiujitsu game, footage has emerged of Zuckerberg appearing to argue a decision in his gi match and, later, pulling on his opponent’s elastic yoga pants in the no-gi roll.

Real hard to tell from the footy taken from the back row but looks like his opponent tries to cross-collar choke the billionaire from Zuck’s closed guard, a classic white belt move that works often enough at the lower levels, either that or he stacks him on his neck, Zuck taps, fight stops, Zuck says he didn’t tap, fight gets recast as a draw, something y’don’t often see in the jiujitsu game.

And, in his no-gi brawl, Zuck starts tearing hell out of his opponent’s plastic tee and pants before the ref pulls him into line.

No comment yet from Kai Lenny who has previously described Zuckerberg as “really cool” and “Super fit. Like … strong, strong strong. Physically strong.”
