Does IFAB law allow for automatic cards to players and/or coaches for equipment issues?
Recently on a few occasions I've been AR for a game played under USSF auspices (so standard IFAB laws), where the referee has warned players at check-in that equipment problems after kick-off will result in a caution (e.g. "make sure all jewelry is off before we start, otherwise it's an automatic caution"). On at least one occasion the referee put the warning to the coach, saying first card would go to the coach, then to the player. Similarly, on a game I was present at as a spectator, I saw a card given to the away coach for earring that were on during play. All of these were very experienced referees who I've worked with and generally know there stuff.
Now, I know that high school rules in the U.S. under NHFS do specify the "first card to the coach, second to the player" for equipment issues, but that's not explicitly in IFAB laws. I believe the referees in question also do some high school, so may just be mixing systems. That said, is there any justification in IFAB laws for giving cautions to players or coaches for equipment issues discovered after kickoff?
Law 4.1 says that "The players must be inspected before the start of the match and substitutes before they enter the field of play. If a player is wearing or using unauthorized/dangerous equipment or accessories, the referee must or the player to:
- remove the item
- leave the field of play at the next stoppage if the player is unable or unwilling to comply
A player who refuses to comply or wears the item again must be cautioned."
I suppose that could be read as saying that if you warn players at check-in to remove things and they don't, they are wearing the item again or refusing to comply, and must be cautioned, but the mention of "stoppage" implies that if unauthorized/dangerous items are found during play, they get at least one chance to remove them. Nothing in law 4 about coaches, but maybe you could stretch "lack of respect to the game" in law 12?
