I don’t think it was the MOB...they don’t beat the crap out of someone, they kill them and hide their bodies for finding later...
But he does look like he’s been beaten pretty badly, and I didn’t agree with the ‘car accident’ either...there is someone after him for something, but the MOB doesn’t just beat you up....

If they are able to USE you and need ‘adjusting’, they will slap you around pretty good.
You only get whacked if you’re beyond usefulness.
