What happens if my child is bleeding or gets hurt during a game?

Under USA Water Polo Rule WP 27:

• Bleeding: the referee immediately orders the player out of the water, a substitute enters straight away and play continues without stopping. Once the bleeding has stopped, the player can come back in as an ordinary substitute.
• Other injury or illness: the referee may stop the game for up to 3 minutes. Play restarts with the team that had the ball putting it into play where play stopped.
• Coming back: except for bleeding, an injured player cannot return to that game once a substitute has entered for them.
• A player may only leave the water, or sit or stand on the steps or side of the pool during play, because of accident, injury or illness, or with a referee's permission.
