Elon Musk said he will receive an MRI of his neck and upper back tomorrow and may require surgery, according to a post on his X platform, formerly known as Twitter.

Musk, the world’s richest person, said he will know this week whether surgery will be required. He challenged Meta Platforms Inc. co-founder Mark Zuckerberg to a fight in June.
