No, you conclude he was hit in the helmet, twisted 180 as he fell so he could land face first did not move so he was knocked out. Smdh. Back to the basement.
Fella, I have been hit in the helmet just like that on the lower flap. Zero head trauma, sore jaw. Stop reaching podner, you are starting to look really bad. You have ZERO clue if he was concussed, if he was knocked out etc. Stop arguing to argue.
