The Vanishing Cast

[mikesears]

Player A56 attempts to come into the game with a cast that is properly padded but he does not have a Doctor's written note. Crew won't allow him to play because he doesn't have a note.

A56 goes to the sideline and tells the trainer to cut the cast off. Against her STRONG medical advice, she cuts the cast off.

Do you allow A56 to play?

I'd appreciate any case book support or rule reference that can be provided.

Thanks!
