No question here, only a clear statement of Law, tradition, and common practice for referees, players, and coaches alike.
1. Players and technical staff are not allowed to communicate via any communication devices:
“The use of electronic communication systems between players and/or technical staff is not permitted.”
2. Other than watches, notecards/pens, and whistles, referees are not permitted to wear or carry any equipment other than what has been approved by the IFAB and the U. S. Soccer Federation. Cell or mobile phones are not among those approved items.
3. Why then would this referee, while play is going on, stop to use his cell phone?
