Offside rule in youth soccer, explained
A player is offside in soccer if they are in the opponent's half of the field and closer to the opposing goal line than both the ball and the second-to-last defender at the moment a teammate plays the ball to them, per IFAB Law 11.
Not offside
- Receiving the ball from a throw-in, goal kick, or corner kick.
- Being level with the second-to-last defender.
- Being behind the ball.
- Being in your own half.
How referees flag it
Assistant referees raise the flag when a player in an offside position touches the ball or affects play. In youth soccer with no assistants, the center referee makes the call.
