Nick Clegg, Meta’s former president of global affairs, reportedly said Mark Zuckerberg insisted that some senior executives join him for an MMA training session at a management offsite. The account describes training and sparring—not a series of closed-door employee fights—and does not establish how many executives attended or whether participation was voluntary.
What did Nick Clegg say happened?
In his book How to Save the Internet, Clegg recounted that Zuckerberg’s commitment to MMA led him to insist that some of his most senior executives join a training session during a management offsite. Entrepreneur reported the anecdote and attributed it to Clegg; the book was published by Penguin on November 11, 2025. Entrepreneur’s account.
TechCrunch reported that Clegg sparred with Meta deputy Joel Kaplan and described Kaplan’s mount as “too close for comfort.” That detail supports an account of sparring during training, not a formal bout or organized match. TechCrunch’s report.
Does this show Zuckerberg made employees fight?
No. The sourced account says he insisted some senior executives join a training session, but the reporting does not establish that employees were compelled to fight, that the session was a formal match, or that similar events happened repeatedly. It also does not say how many executives attended. Clegg’s wording is the basis for the anecdote; it is not evidence of a recurring employee-fight event.

The distinction matters: the reports’ descriptions of training and sparring do not substantiate the stronger headline claim of employees fighting in closed-door matches. The sources reviewed do not include a direct statement from Zuckerberg, Meta, or Kaplan about whether attendance was voluntary.
How is this different from Meta’s risk disclosure?
In a separate matter, Meta’s 2024 investor disclosure said Zuckerberg and certain other management members participate in high-risk activities, including combat sports, extreme sports, and recreational aviation. The filing warned of the risk of serious injury or death and said Zuckerberg’s unavailability could materially adversely affect Meta’s operations. MMA Fighting quoted that disclosure. MMA Fighting’s report.
Rank #2
That statement concerns business-continuity risk from activities involving Zuckerberg and some managers. It does not say that employees took part in the offsite training session or confirm employee matches.

In a separate personal-training episode, Zuckerberg said he tore his ACL while sparring as he trained for a competitive MMA fight planned for early 2024. He said the fight would be delayed while he recovered. MMA Fighting reproduced his Instagram statement. MMA Fighting’s report on the injury.
Rank #3
His injury is not evidence about what happened at the management offsite. The two accounts concern different events: his personal training and Clegg’s recollection of executives joining a training session.
