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: Concussions

September 15, 2016

This week, MHSAA assistant director Mark Uyl discusses the official's role when an athlete experiences a possible concussion.

Below is this week's segment – Concussions - Listen

In all contact sports, the biggest issue of the day continues to be concussions. Game officials play a vital role in keeping athletes safe on the field, court, ice and mat.

While officials are never placed in the position to diagnose a possible concussion, the officials can often see when a player first becomes injured. When that possible injury is noticed by an official, all game rules require the contest be stopped and the student is evaluated by the school’s health care team.

It then becomes the call of the school to determine if the player has suffered a possible concussion. If yes, the player is out for at least the rest of that day. If no, the player can return to the contest.
