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.

A Leading Official
July 29, 2014
For more than a decade, Mark Uyl has been the MHSAA’s leader of service and support to officials. Mark’s calm demeanor and subtle sense of humor have much to do with his successful leadership of what we sometimes call “the complaint department;” but because he has been both, Mark has a good feel for and the respect of both school administrators and officials.
Since joining the MHSAA staff in January of 2004, Mark has continued to referee college football and baseball. Last month Mark worked the NCAA College World Series in Omaha which had been a long-time goal for this still very young man.
This week Mark ascends to chair of the board of directors of the National Association of Sports Officials (NASO).
It’s clear that Mark has as fine a reputation nationwide as he enjoys here in his home state.
