About 10 minutes into a game, it was noticed that one of the players was not wearing shin guards. The laws state that the ref can either wait for the next stoppage or go ahead and make a stoppage and order the player off the field to fix the problem and that player cannot return without the ref’s permission.

The laws do not talk about subs in this situation so I interpreted that to mean that a substitution could not happen. Is that right?

Does the team remain down one player until the next stoppage and the ref calls on the sub or can the team immediately send in a sub while the one without the proper equipment is being sent off? It seems as though if the team is allowed an immdiate replacement on the fly, it would give them a tactical advantage if allowed since the other team would not be able to piggy back on it or sub in a one for one sub like with injuries.
Lastly, if the ref stops the game for the equipment infraction, is the restart a dropped ball or an indirect for the opposing team at the spot of where the sent off player was seen with the missing gear?

My decision at the time was to stop the game, I sent off the player (I cautioned the player but did not show the yellow), the coach tried to send another on in the meantime and I denied it, restarted with a dropped ball where it was when I stopped the game, and the team played down one until the next stoppage.

Thanks in advance for any advice on such a situation.

Answer (November 17, 2013):
I cannot guarantee what your local rules may say, as some local rules are—like high school rules—from another planet. However, under the Laws of the Game a team may substitute at ANY stoppage of play with the referee’s permission. It cannot be done on the fly, as that is not the way substitutions are handled—again unless your local rules are from another planet. To caution the player, you must believe that he willfully broke the Law. See this quote from the back of the book, Interpretation of the Laws of the Game and Guidelines for Referees (Law 4):

Disciplinary sanctions
The players are to be inspected before the match begins and substitutes before they enter the field of play. If a player is discovered to be wearing unauthorized clothing or jewelry during play, the referee must:
• inform the player that the item in question must be removed
• order the player to leave the field of play at the next stoppage if he is unable or unwilling to comply
• caution the player if he willfully refuses to comply or, having been told to remove the item, is discovered to be wearing the item again
If play is stopped to caution the player, an indirect free kick must be awarded to the opposing team from the position of the ball when play was stopped (see Law 13 – Position of free kick).
