LEWES, Del. – An atheist group is questioning a Delaware school district after it says a high school football coach joined players in a prayer after the game.

The Freedom From Religion Foundation sent a letter to the Cape Henlopen School District, saying Cape Henlopen football coach Bill Collick committed a constitutional violation by praying with his team.

The foundation’s president says that a coach has to be religiously neutral while acting in an official capacity.

WXDE-FM in Lewes reports that the school district did not return a call seeking comment.

The Madison, Wisconsin-based foundation says it is an educational group committed to maintaining a separation of church and state.
