1st time this occurred, I would issue a sideline warning, not a verbal an actual warning, during administration I would advise coach, I gave you the warning so I didn’t have to give you an illegal substitution.
I would advise the coach if you want to huddle like this only 11 players and stay in the coaches box. If there are 12 in the huddle longer than 3 seconds it will be a illegal substitution.
Problem solved without a yardage penalty, play on, stick to your word.
