Duties

Two assistant referees may be appointed whose duties, subject to the decision of the referee, are to indicate:

• when the whole of the ball leaves the field of play
• which team is entitled to a corner kick, goal kick or throw-in
• when a player may be penalised for being in an offside position
• when a substitution is requested
• when misconduct or any other incident occurs out of the view of the referee
• when offences have been committed whenever the assistant referees have a better view than the referee (this includes, in certain circumstances, offences committed in the penalty area)
• whether, at penalty kicks, the goalkeeper moves off the goal line before the ball is kicked and if the ball crosses the line
