How do I indicate when the ball is out of play for a throw-in, goal kick or corner?

Question

Accepted Answer

Under Law 6.1, the assistant referee indicates when the whole of the ball leaves the field of play and which team is entitled to a corner kick, goal kick or throw-in. The flag signals themselves are shown in the approved assistant referee signal graphics in Law 6.6 on the IFAB site.

IFAB's example: if you indicate a throw-in for Team A and a Team B player quickly picks up the ball and throws it in before the referee intervenes, the throw-in is retaken by Team A from the same position, with no disciplinary sanction for the Team B player.
