I'd like to put on record how we deal with dismissals on the field of play in our sport (we call them "ejections" or "disqualifications") - which I know is going to sound very weird as to how we do things.
Both teams are mandated pre-game to supply a full roster of their team - with numbers and names on them.
19.1 - In the event of a disqualifying foul:
- The official who has penalised the player to be disqualified accompanies the Referee to notify the Head Coach of the number of the player disqualified and the nature of the foul.
- When notifying the Head Coach, the recommended wording is "X just disqualified himself because ..." or "X is disqualified because ...", rather than "I am disqualifying X because ...".
- [REFEREE] If you called the foul, the wing official (Linesman or Line Judge) should accompany you.
- Another official (normally the opposite wing official) should inform the opposing Head Coach of the disqualification.
After this - we announce the penalty and the reason to the rest of the stadium.
