Can a captain who was ejected in the first quarter participate in the overtime coin toss?

A captain who has been ejected from the game cannot participate in any further activities, including the overtime coin toss. According to NFHS rules, once a player is ejected, they lose their right to be involved in all aspects of the game for its duration. This maintains a standard of conduct and discipline within the game, ensuring that players who have been dismissed due to penalties do not influence the game's outcome afterward. Therefore, the correct answer reflects the rule that ejected players are barred from all further participation.
