Time to play "what if". NF rules. Prior to the start of a game, you notice a player is wearing what seems to be a religious piece of jewelry on a chain around his neck. You inform the coach that it is to come off, but if the player insists that the item is part of his religion and he must wear it, he can - however it must be taped under his uniform onto his body. The coach informs the player of this and the player calls his father out from the stands. The father informs you that the symbol cannot be taken off due to religious reasons and cannot be "taped over" because that would be disrespectful and would be "against" their religion.
Forget bringing into the equation what the player has done in prior games. What would you do, assuming it would be impossible to get the parents of all the players on both teams to sign a liability waiver.
What would you do? And no - this has never happened in one of my games and I have no idea why I was thinking of it.
