In a U-19 game today, a fight broke after the game was over. It was at least 8 players from each team. Is it ok for an AR to grab a kid in a head lock and drag him away from the fight?

USSF answer (March 5, 2012):
Under normal circumstances match officials should not touch any player for any reason other than to shake hands before the coin toss or after the game is over. Breaking up fights should normally be left to the teams themselves. In most cases the only justification for an official to “step in” (particularly if that term is meant to include touching or holding a player) is for self-protection … and only to the extent needed for self-protection and only for as long as self-protection is needed.
