You are the sideline physician for a local high school football team. During a district playoff game, the starting quarterback is sacked for a loss on third down. As the punter heads out onto the field, the quarterback is slow to come to the sidelines. He seems confused and dazed. Aside from his confusion, his examination is normal. After 10 minutes, he is lucid and wants to get back into the game. Based on published guidelines, which of the following is your correct course of action?
a) Allow him to return to play
b) Monitor him for the rest of the game
c) Refer him to the emergency room
d) Withhold him from play for the remainder of the game
