Elon Musk accepts Georges St-Pierre's offer to train for proposed UFC fight with Mark Zuckerberg.

Elon Musk has accepted Georges St-Pierre's offer to train him for a proposed UFC fight with Mark Zuckerberg. The potential fight came about after Zuckerberg accepted Musk's challenge during a social media spat. UFC president Dana White said both men were "dead serious" about meeting inside the cage and that he welcomed building a UFC pay-per-view event around a headliner of Musk vs. Zuckerberg. Zuckerberg, who has a background in jiu-jitsu, has yet to publicly accept any offers to train.
