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.

Below is this week's segment – 40-Second Play Clock - Listen
There’s an experiment taking place on a number of high school football fields across the state again this year. Michigan is experimenting with a 40-second play clock in football.
This is designed to provide more consistency from play to play as the ball must be snapped 40 seconds after the end of the previous play and is not dependent on the referee’s subjective signal.
When play is continuing without a stoppage, the 40-second play clock will be used. If play has been stopped for a time out or penalty, the play clock will be set at 25 seconds.
After two seasons, the feedback received from coaches and officials has been very positive, and there’s a possibility the Michigan experiment may become a new national playing rule soon.
