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.

Be the Referee: Field Hockey Substitution

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 Substitution - Listen

We are on the pitch today for a field hockey “You Make the Call.”

During the execution of a penalty corner, the defending goalkeeper is struck on the hand and cannot continue. How is play resumed?

  • Allow a properly equipped goalkeeper to substitute.
  • Disallow any substitution; the injured goalkeeper must remain in the game.
  • The defending team shall forfeit.

If you said to allow the substitution, you are correct. Under Rule 4-4-3, a goalkeeper substitution is permitted during a penalty corner in the event of injury or suspension. Once the new goalkeeper is ready, resume play with the continuation of the penalty corner.

Field players, however, may not substitute until the penalty corner has been completed. This ensures proper game flow while prioritizing player safety.
