What action must a head coach take when an administrative yellow card is issued for unnecessary delay?

When an administrative yellow card is issued for unnecessary delay, the head coach is not required to remain seated during play. This situation typically arises as a penalty for actions that affect the pace of the game, but it does not impose a restriction on the coach's ability to stand and actively engage with their team or the match situation. Coaches have the flexibility to move around and communicate with players, ensuring that they can motivate and give feedback despite the penalty. This understanding allows for more dynamic coaching during the match while still acknowledging the infraction that led to the yellow card.

The other aspects related to the consequences of an administrative yellow card, such as requiring the coach to leave the coaching area or to lose the opportunity to call timeouts, do not apply in this context, hence reinforcing that the coach remains permitted to stand.
