I agree that we want to be cautious and err on the side of safety. But I know that I've been dazed after colliding with a player and clearly not been unconscious. I don't think that being dazed -- which I associate with shaking the cobwebs out of your head -- is automatically the same as being unconscious, as Mark seemed to imply above. JMO.
