Elon Musk bragged about lifting ’45 lb weights’ on Friday. Now he says he has to get an MRI on his neck and back and may need surgery before his cage match with Zuck.

• Elon Musk said he couldn’t confirm a date for his fight with Mark Zuckerberg just yet.
• Musk said he was getting an MRI of his neck and back, and might even require surgery before the fight.
• It looks as if the cage match isn’t going to happen anytime soon if Musk’s got to go under the knife.

Elon Musk may be set on live-streaming his fight with Mark Zuckerberg, but he wants to get his neck and upper back checked before fixing a date.

“Exact date is still in flux. I’m getting an MRI of my neck & upper back tomorrow,” Musk wrote on Sunday night, responding to a tweet about Zuckerberg waiting for his confirmation to set a date for fight night.
