I would keep him quiet in case he's got a slow bleed. Activity could increase the tear/rupture in any injured brain vein/small artery. You know of people that die from a slow bleed from the tear of a small vein in the brain a day later after the head injury that seem fine at first. Hate to scare you but you have to consider that right now and just face that with any head injury. Not saying he's got that but you want to consider it. Just watch him, watch his pupils to be sure they stay equal in size and react to light and one doesn't get irregular, that he doesn't throw up or act dizzy or lethargic. Wake him frequently and check his pupils, breathing, pulse rate and whether he's walking normally and coordinated. You have got to have a vet see him if he starts to go down and shows there is something wrong, say the bleed is large enough to cause swelling and pressure on the brain. Get him in to the vet as soon as you can tomorrow to be sure he's really okay.
