I got jumped and robbed last night. Knocked upside the head by something, a brick maybe. Have a minor jaw fracture, cheekbone fracture and sustained a mild concussion. Don't remember anything from 30 minutes before til 3-4 hours later. Apparently I was conscious though. How can guys be put back on a football field after that I don't know. Granted, maybe he didn't get hit as hard as me but it looks like he had similar symptoms.
