Nothing. No bruise. Nothing. It turns out, he got headbutted, thrown into a fence, fell down, got thrown a little, THEN got stepped on. Sure he's sore and it hurts to move, sit down or stand up, but there is no physical evidence of getting his ass kicked (pun?) by a thousand pound creature. If that had happened to me, I would be radiating black and blue from my butt over my entire body.
