Be the Referee: Field Hockey Substitutions

October 27, 2026

Be The Referee is a series of short messages designed to help educate people on the rules of different sports, to help them better understand the art of officiating, and to recruit officials.

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.

What's My Why: Official Cindy Tyzo

June 8, 2026

Cindy Tyzo, West Bloomfield

Tyzo is one of what surely are only a handful of officials who have been registered for two MHSAA-sponsored sports since their first seasons as part of the championship lineup. She's is completing her 33rd year overall after first registering for the inaugural season of competitive cheer in 1993-94, and she also officiated the first season of MHSAA field hockey this past fall. 

Tyzo also just completed her eighth season officiating girls lacrosse. 

I love officiating because I love working with the young people and providing the opportunity for them to do the sport that they love. Because without officials, there's not game.

“What’s My Why” is a weekly feature telling the stories of MHSAA-registered officials in their own words. If you’re an MHSAA official and would like to share your reason why, please submit a 15 to 45-second video, taken horizontally, to director of officials Sam Davis at [email protected].
