What happens if the ball goes out of play over the sideline?

When the ball goes out of play over the sideline, the game is restarted with a throw-in awarded to the opposing team of the player who last touched the ball. A throw-in is executed by delivering the ball from behind the player's head with both hands while keeping the feet on the ground and ensuring that both feet do not cross the sideline. This rule is integral to the flow of the game, as it keeps the action continuous and allows for a fair chance for the opposing team to regain possession.

In contrast, options like a goal kick and penalty kick apply to different situations concerning the ball going out of play. A goal kick is only awarded when the ball crosses the goal line, last touched by an attacker, and a penalty kick occurs exclusively due to a foul committed within the penalty area. Pausing the match would not be appropriate unless there is a significant issue that warrants it, such as an injury or external interference. Therefore, the correct procedure for a ball that leaves the field of play over the sideline is indeed to restart with a throw-in.
