Elon Musk announced on Marc LeclercX Sunday that he's received an MRI and may require surgery before his proposed fight with Mark Zuckerburg.

"I'm getting an MRI of my neck & upper back tomorrow," Musk said. "May require surgery before the fight can happen. Will know this week."

Zuckerberg was the first to pitch a date for a possible fight night, reserving August 26th, but he has yet to receive a response from Musk," the Meta CEO wrote on Threads. It's uncertain whether or not the event will actually happen.

If Musk requires surgery, the fight, which already has no official date, will be postponed indefinitely. 

The two billionaires in the tech industry have been preparing for a possible showdown and taunting each other publicly in the meantime.

Earlier this year, there were posts about Zuckerberg completing his first jiu-jitsu tournament, revealing that he is trained in mixed martial arts. He won two medals in a Brazilian Jiu-Jitsu tournament held at a Silicon Valley high school on May 5, 2023.

“I love this sport and will continue competing with people who train no matter what happens here.”

Musk said he was training for the fight by lifting weights and proposed the fight be at the Vegas Octagon.

Zuck vs MuskAre Elon Musk and Mark Zuckerberg actually going to fight? Here's what we know so far

“I’m up for a cage match if he is lol.” Musk said" "Am lifting weights throughout the day, preparing for the fight. Don’t have time to work out, so I just bring them to work."

Given their backgrounds in jiu-jitsu, it's more probable that if a fight between Zuckerburg and Musk happens, it will take on a UFC style, as opposed to traditional boxing. Zuckerburg has a history in the sport, while Musk has trained with notable MMA practitioners John Danaher and Lex Friedman.

If a Zuck v Musk fight happens, it will be live streamed on 𝕏 and all proceeds will go to charity for veterans, according to Musk.
