6.B.6 AFTER SIGNALLING FOUL PLAY

A match organiser may give authority to the assistant referee to signal for foul play. If an assistant referee signals foul play, the assistant referee must stay in touch and continue to carry out all the other duties until the next stoppage in play. At the invitation of the referee the assistant referee may then enter the playing area to report the offence to the referee. The referee may then take whatever action is needed. Any sanction awarded will be in accordance with Law 10 – Foul Play.
