Mark Zuckerberg, founder of Meta (Facebook), injured his cruciate ligament in his knee and was hospitalized. Zuckerberg published corresponding photos.

“I injured my knee tendon during sparring (training fight). There was a need to replace it, the operation was successful. I was preparing for the fight, but I will have to postpone it," Zuckerberg wrote.

For reference: Zuckerberg was supposed to fight Elon Musk in MMA (mixed martial arts). This fight was supposed to take place in the first half of 2024, and the proceeds were to be spent on charity. The fight was planned to be broadcast on social networks.
