Sylvester Stallone is advising other actors against doing their own stunts. The Rambo actor revealed on the new season of his reality show, The Family Stallone, that he had to have seven major surgeries after former professional wrestler Steve Austin body slammed him while filming The Expendables in 2010.

“I did stupid stuff. I was directing ‘Expendables‘ and, like an idiot, I’m doing take 10, take whatever, and I remember one slam and I could actually feel one bang,” the Rocky actor said. “Steve knew … I never recovered from ‘Expendables 1.’ After that film, it was never physically the same. I’ve warned people: Don’t do your own stunts.”

Stallone ended up needing a metal plate in his neck, spinal fusions, and treatment for dislocated shoulders.
