ONE Flyweight Submission Grappling World Champion Mikey Musumeci is preparing for his next battle inside ONE Championship, and part of that preparation has seen him cross paths with Meta mogul Mark Zuckerberg.
Musumeci will return to ONE Championship in an openweight submission grappling bout against former ONE Lightweight World Champion and grappling royalty Shinya Aoki at ONE Fight Night 15 on Saturday, 7 October.

"Darth Rigatoni" has been working with Zuckerberg, who's also training to compete in MMA for the very first time in the near future. In fact, he had his eyes set on Tesla and SpaceX owner Elon Musk.
But while some fans have a slanted view of the battle of the billionaires, Musumeci has been impressed by "Zuck's" commitment to his combat sports journey. And with his skills continuing to multiply, Musumeci predicts success in Zuckerberg's competitive career.
"I was pretty shocked. [Mark's] a grinder. He has that grind in him. The second I saw that I said, 'Okay, he can be very good at MMA or jiu-jitsu' because he has the highest IQ, but he's also tough as f***," Musumeci told TMZ Sports.
Whether or not Mark Zuckerberg takes on Elon Musk, the social media pioneer wants his debut to take place inside either the UFC or ONE Championship. After all, either one of the two largest martial arts organizations would bring the most eyes to Zuckerberg's inaugural outing.
Having been fascinated with Zuckerberg's dedication to his craft, ONE Chairman and CEO Chatri Sityodtong thinks ONE Championship would suit the Facebook founder's mantra perfectly.
"I can tell you Mark is a real martial artist. He's obsessed. He's only been training two years, so he's relatively new, but he's a legitimate blue belt in Brazilian Jiu-Jitsu. I'm genuinely very impressed with his set up and Mark's dedication to martial arts," Sityodtong said.
"We're definitely open [to Zuckerberg competing in ONE]. And I don't think it would take a long time. He's already having backyard fights in his cage. He's practicing all facets of MMA, and he's doing it from a place of love which is different to what Elon's doing."
