Whilst looking over the updated laws, I formulated a few questions which don't necessarily relate to incidents I have faced. It is a list that will probably grow and grow! Law 4--Players' equipment There isn't much specific in the laws about what constitutes dangerous footwear. We are required to undertake pre-match checks, but I am not really sure what I would deem unacceptable. I always notify a player when they have missing studs, but unless the hole has sharp edges, I never have a problem. Law 15--Throw-in As an addendum to the clause whereby a referee shall allow play to continue if the taker throws the ball at an opponent in a manner that isn't reckless or with serious force, it would be useful if they had clarified that either of these two warrants a yellow or red card as appropriate and that the referee should award a direct free kick to the opponent. Currently it could be interpreted that you should order a retaken throw after sanctioning the offender. Law 12--Fouls and Misconduct To turn the classic scenario around, are there any offences (whilst the ball is in play) against players by substitutes, match officials, club officials or outside agents that can result in a free kick, or would it always be a dropped ball?
