The Dr. Note for an Unconscious Player

[WooPigSooie]

I have a question about the Dr. note procedure to allow an unconscious player back into the game. Ok, player knocked out. Unconscious. After halftime, the coach hands me a note from a physician stating player can come back in.

First of all, do I accept this note from a coach, player, or parent? For all I know, the school janitor could have thrown the letters DR in front of his name and said 'sure, you can go back in'. Or, do I accept this from a physician hand to hand.

Second, disregarding worrying about the above scenario, once I get this Dr's note, what do I do with it? Do I keep it and file it in a safe place after the game for liability issues? Do I give it to someone else?

Where, if any, does liability lye with the official? Once I see doctor's note signed by 'Dr. John Doe, MD', I just accept it and go on, or do I need to worry about authenticity? Do I keep the note and put it in safekeeping?

Any clarification would be great. Maybe I am overly scared over this, but having a background in the medical field, we take an entire course in legal liability and I have seen how stringent the law can become as far as determining liability.
