Jon Jones Offers To Train Mark Zuckerberg For Fight Against Elon Musk

If Mark Zuckerberg really gets in the Octagon with Elon Musk, he'll have arguably the greatest fighter ever in his corner ... 'cause Jon Jones says he's down to train the Facebook billionaire!!

Bones took to Twitter Thursday night to offer his support to the 39-year-old Meta boss ... writing, "You already know I am Team Zuck ... Let me know if you need a training partner!"

As we previously reported, a fight between the two billionaires could actually happen ... with UFC honcho Dana White telling TMZ Sports both sides are serious about scrapping.

Of course, the weight difference between Elon and Zuck may pose a problem ... but Jones made it clear he'll be at the ready in case things move forward.

Jones' bond with Zuck goes back a few months -- in February, he commented on a video of Mark sparring with UFC champion Alex Volkanovski in the Metaverse ... saying the techy training looked like a blast.

Zuck wished him well ... replying, "Excited for your return!" ahead of Jones' first-round win over Ciryl Gane.

Now that one of the G.O.A.T.s is getting involved, the hype surrounding the potential fight is even greater.
