What happens when a player is found to be in an offside position at the moment the ball is played?

When a player is found to be in an offside position at the moment the ball is played by a teammate, the appropriate action is to call them offside, which results in the opposing team being awarded an indirect free kick from the spot where the offside violation occurred. The offside rule is designed to prevent players from gaining an unfair advantage by positioning themselves closer to the opponent's goal than both the ball and the second-to-last opponent at the time the ball is played. This helps maintain the flow of the game and ensures fairness in play.

The other options do not align with the rules regarding offside. Showing a yellow card is not warranted unless there is misconduct, such as a deliberate foul, that occurs separately from the offside call. Allowing the play to continue without interruption or permitting the player to play on goes against the enforcement of the offside rule, which is strictly observed during matches. The proper protocol after an offside violation is clearly defined to uphold the integrity of the game.
