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: Clipping Clipped

August 25, 2016

MHSAA assistant director Mark Uyl opens a new year of “Be the Referee” by explaining the latest rules change affecting blocking in football.

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 – Clipping in the Free Blocking Zone - Listen

Most of the recent rules changes in high school football have all dealt with increasing player safety. The most significant change for the 2016 season focuses on safety, especially for offensive and defensive linemen.

For many years, the free blocking zone (the area between the two offensive tackles) was an area where two types of blocks – blocks below the waste and clipping, that are illegal on other parts of the field – were legal if done by linemen initially at the start of a play. For this season, clipping is now an illegal block, even in the free blocking zone, while blocks below the waste continue to be legal from in front.
