The protocol is VERY clear in the Game Management Guidelines (which we hope every whistle monkey has read):
Verbal abuse by team coaches, team staff or team substitutes directed at match officials or players should not be tolerated and the following process should be followed:
1. The referee will ask the identified person to refrain from their behavior.
2. On the second occasion the referee will EJECT the person from the grounds.
3. Zero tolerance approach should be applied and if the person refuses to leave the referee should request that team’s captain to assist.
4. Failing compliance the referee may abandon the match.
NOTE: The referee must restart the game according to the latest stoppage and must NOT award a penalty due to the sideline behavior.
Review and heed!
