WASHINGTON, June 24 (Reuters) - Elon Musk said on Saturday he will start training if the mixed martial arts cage fight he has provoked with fellow billionaire media mogul Mark Zuckerberg takes shape.

Mixed martial arts fighting is one of the biggest sports in the U.S., and the Cage Rage Championships is one of the world’s most recognized branded sports events, rivaling Formula One and soccer.

It’s aimed at fans of mixed martial arts (MMA), professional wrestling, underdog stories and surprisingly good acting (where it might not have been expected). And it works on all levels.
