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.

Be the Referee: Intentional Grounding

This week, MHSAA assistant director Brent Rice explains football intentional grounding at the high school level. 

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 – Intentional Grounding – Listen 

A quarterback is under heavy pressure and immediately throws the ball away. International grounding, right? Maybe. And maybe not.

What goes into an official deciding if grounding has occurred?

First, there is no such thing as a “tackle box” in high school football as it pertains to grounding. A quarterback scrambling outside of the tackle box who throws the ball away could still be penalized for grounding – even if it reaches the line of scrimmage.

Any pass can be penalized for grounding if there is no receiver in the immediate area. Behind the line, inside the tackle box – none of that matters – it only matters if there’s a potential receiver nearby. If there is – no grounding. If there’s not – there will be a flag on the field.
