When a throw-in is taken incorrectly or from a place other than where the ball crossed the touch-line. A foul throw can be given by the referee with the help of the assistant referee.
What makes a throw-in Illegal in Soccer?
- The player taking the throw-in must be facing the pitch with parts of both feet on or behind the touch-line in the position the opposing team put the ball out. If any part of the player’s feet crosses over onto the field the throw-in is not legal.
- Once the player is in position and ready to take the throw-in they must throw the ball using both hands and the ball must come from behind and over their head. A throw-in is deemed to be illegal if the ball is thrown with one hand, underarm, or sideways .
- The player taking the throw-in cannot touch the ball first once the play is live, it must be a teammate or opposing player. If this happens an indirect free kick is awarded to the opposition.
- A goal cannot be scored from a throw-in unless the ball has touched a player from either team before crossing the goal-line. If the ball crosses the opponent’s goal-line then a goal kick is given to the opposing team. However, if the ball crosses the thrower’s goal-line, the opposing team is given a corner.
- If the player decides to throw the ball back to his goalkeeper then they must not pick the ball up as this breaks the ‘back-pass’ rule, which prevents goalkeepers from handling a ball played by a teammate.
