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: 40-Second Play Clock

August 29, 2019

This week, MHSAA Assistant Director Brent Rice explains the change in football to a 40-second play clock.

Below is this week's segment - 40-Second Play Clock - Listen

One of the rules changes in high school football this year involves timing between downs.

All varsity games will be played with a 40-second play clock that begins after the conclusion of the previous play, with exceptions for things like timeouts, penalties, measurements and at the start of a period – when a 25-second count will be used.

In experiments in Michigan over the past few seasons, the 40-second play clock proved to improve the pace of play and consistency between plays because it is not dependent on the referee’s subjective signal. And while some schools may choose to purchase visible play clocks for their fields, it is not required. The Back Judge, who has the primary responsibility for the play clock, will signal at 10 seconds and count the last five seconds.
