9. Ball In and Out of Play - According to the official soccer rules, the ball is in play all throughout the match duration, except when it passes a bounding line (goal lines and touch lines), when an offence occurs or when play is stopped by the referee. In these particular cases, the ball is out of play and the soccer players cannot score goals or interact with the ball. In addition, substitutions can only occur when the ball is out of play according to the rules for the game of soccer.
