Elon Musk says he may need surgery before proposed 'cage match' with Mark Zuckerberg

 NEW YORK (AP) — Elon Musk says he may need to get surgery before a proposed “cage match” with Mark Zuckerberg. 

“I’m ready today. I suggested Aug 26 when he first challenged, but he hasn’t confirmed," wrote Zuckerberg, who is actually trained in mixed martial arts and posted about completing his first jiu jitsu tournament earlier this year. "I love this sport and will continue competing with people who train no matter what happens here.” 

Earlier Sunday, Musk said was training for the fight by lifting weights. He later addressed the timing of the fight — noting the date “is still in flux" due to a scheduled MRI and the potential of surgery. 

"I’m getting an MRI of my neck & upper back tomorrow," Musk wrote Sunday night. "May require surgery before the fight can happen. Will know this week."
