Ran across this gem(gym) if someone really in need of rehab

viewer discretion advised

(TLDR a Russian lifted attempts a 550lbs back squat and snaps his femur) reading the accompanying article the athlete had apparently been complaining about the pain in his leg previously and was in pain killers to mask it. During his first attempts he wasn’t even able to squat. Thoughts?

Also if an RPE @10 is bone on bone grind what would you rate this?

I think that it may or may not be related as to the reason why this freak accident occurred. It was ultimately his decision to lift or not. Hope he’s ok.
