THEREFORE you are reminded that you should not sign up for any games that are of the same age and gender as your relative.
The exception to this rule is that a player MAY be substituted if they are injured. If they are replaced because they are injured, they may not re-enter the match.
An important little twist does exist on this rule. Imagine that you notice a player is bleeding. You know that a player may not remain on the field if they are bleeding. Therefore, you stop play and ask the player to leave the field. If the coach chooses, they MAY play short, take care of the bleeding player, and the player MAY reenter the game (when you give permission), because the player has never been substituted. The same thing holds true in the case of any injury. The player has not been substituted out of the game until the coach sends in a replacement player. If the Overtime period ends while the player is still being treated, the coach still has the option to either substitute the player (as an injured player), or allow the player to participate in the shoot out.
