Below is this week's segment – Field Hockey Substitutions - Listen
We’re on the pitch today for a field hockey “You Make the Call.”
The white team is awarded a penalty corner. During the penalty corner, a red team substitute enters the field but does not participate in or affect play.
Should the official stop play immediately or allow play to continue?
If you said allow play to continue, you are correct. Since the illegal substitute has not participated in or affected play, stopping play immediately would give the defending team an unfair advantage by interrupting the attacking team's scoring opportunity.
Under NFHS Rule 4-4-3, substitutions are not permitted during a penalty corner, except to replace an ill, injured, suspended or disqualified goalkeeper. Officials must recognize the violation and know when to hold the whistle to allow for advantage.

Be the Referee: Helmet Comes Off
October 26, 2017
In this week's edition, assistant director Mark Uyl discusses a recent football rules change geared to improve safety in situations after a player's helmet comes off during play.

Below is this week's segment – Helmet Comes Off - Listen
All rule changes in the game of football, at all levels over the past decade, have been geared mainly to improve player safety.
One of the rules that has come recently deals with players and their helmet. Whenever during the course of play a player’s helmet comes off during the down, that player must leave the game for a minimum of one play for an evaluation to take place to make sure that no possible concussion or head injury has occurred.
Plus – when that helmet comes off a player – we treat that just like an injury situation, to where even a timeout can’t buy that player back into the game to make sure that the proper evaluation has taken place.
