Below is this week's segment – Concussions - Listen
In all contact sports, the biggest issue of the day continues to be concussions. Game officials play a vital role in keeping athletes safe on the field, court, ice and mat.
While officials are never placed in the position to diagnose a possible concussion, the officials can often see when a player first becomes injured. When that possible injury is noticed by an official, all game rules require the contest be stopped and the student is evaluated by the school’s health care team.
It then becomes the call of the school to determine if the player has suffered a possible concussion. If yes, the player is out for at least the rest of that day. If no, the player can return to the contest.

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.
