What happens if you get knocked out at school? For a book?

LOL,, doors are like that at my school too,,buhh probably 5 mins or less, & th if he is even unconscious your skull can take alot more damage then you think,, & you said he's spring so he would get hit in the forehead/ face area & the back of the skull is the weakest area of the head so I doubt he'd be knocked out,,, & the teachers would take him to the office & call his parents and or an ambulance depending on sustained injuries.
