A. An illegally-equipped player scores a goal. The illegality is 1. jewelry; 2. no proper shinguards.
B. An improperly-equipped player scores a goal. The improper equipment is 1. proper shinguards worn on the side of or behind the calf rather than the front; 2. undergarments that are a different color from all the other players undergarments.
Obviously, A should be corrected during pregame inspection, but some referees are less diligent. With regards to B, sometimes players move their shinguards to the outside because they’re more worried about challenges from the side rather than straight on. The mis-colored shorts were rolled up during pregame and then fall down during play and are not discovered until after the goal is scored.
The equipment is pointed out before the restart of play. In all cases, does the goal count? Is the player cautioned? If so, how is this misconduct characterized in the report?
USSF answer (June 11, 2011):
The referee and other officials on a game are expected to maintain vigilance at all times for violations of the requirements all the Laws of the Game. In these cases (both of which we sincerely hope are hypothetical), the requirement of Law 5 for a complete inspection of the players prior to the game was not fully met. The requirement for players to wear proper equipment continues throughout the game; it does not stop after the initial pregame look-see.
The purpose of the game is to score goals. In these particular cases, the referee should first be concerned with whether or not the irregular/illegal equipment had an effect on the opposition. In other words, did it lead to the goals? If not, then the referee should allow the goal(s) and punish the infringements of Law 4 with a caution for unsporting behavior.
