What are team officials allowed to do during a football/soccer game?
What happens if…
The head coach is shown a red or yellow card (depending on the offence).
This is allowed.
This is allowed, as long as it does not cause arguing, dissent, protests, etc.
They must be shown on the team list as a substitute and not as a team official. They are allowed to act as a coach until they go onto the pitch to play.
