1. A game was being played during hot weather. A player came to the sideline for a drink of water without leaving the field of play. As he was taking a drink the ball came his way and he took off dribbling the ball with water bottle (plastic) in hand.
Which Law has he broken?
Should the player be cautioned?
What would the restart be?

2. During a game the ball had been hit hard and was certainly going out of play with no players ever getting a chance of making it to the ball to stop it. As the ball headed towards a coach he put his foot on the ball to stop it from going way beyond the field of play. The problem is that the coach stopped the ball before it had gone out of play.
Has the coach entered the field illegally? And should he be cautioned as such? And a Free Kick awarded to the opposing team?
Is the coach treated as an “outside agent” in this instance and a drop ball used to restart play?
Or do we recognize it as a glaring error by the coach who had good intentions and award the throw as if the ball had gone out of bounds?

USSF answer (October 10, 2011):
1. As he had not left the field, the player committed no offense by playing the ball; however, by carrying the unauthorized bottle of water with him, he was playing in violation of the requirements of Law 4. If a player is discovered to be wearing (in this case “carrying”) unauthorized equipment during play, the referee need not stop play, but should immediately inform the player that the item in question must be removed from the field. The player must leave the field only if he is unable or unwilling to comply and could be cautioned if he willfully refuses to comply or, having been told to remove the item, is discovered to be carrying the item again.

2. No, the coach (or any other team official) is not regarded as an outside agent. Team officials are in a separate category under the Laws. (See the Interpretation of the Laws of the Game and Guidelines for Referees in the back of the book.)

Despite the coach’s good intentions (keep this in mind), he has entered the field without the permission of the referee. Under the Laws of the Game coaches cannot and must not be cautioned or sent off and shown any card at all (unless the rules of the competition require it); however, they can be expelled for irresponsible behavior, one example of which is entering the field without permission. If, as in this case, we recognize the coach’s act as motivated by good intentions, rather than any base desire to aid his team (and his earlier actions in the game will provide a good gauge for this decision), the referee will stop play immediately, because the coach has interfered with play. If the coach’s behavior is irresponsible the referee must expel him from the field of play and its immediate surroundings. In this case, the referee will have a quiet word with the coach and restart play with a dropped ball in the position where the ball was at the time when the match was stopped.
