Below is this week's segment – On the Line - Listen
I’m on the line today … but am I in or out?
Have you ever stopped to think about how the boundary lines of a field or court mean different things in different sports?
In basketball for example, if the ball touches the baseline or sideline, it’s out of bounds. Same if a player is in possession of the ball and touches the line.
Football is the same. A player is out of bounds if that player has the ball and touches the sideline.
But in soccer? The ball is still in play until it completely passes the line. If the ball is sitting on the line, it’s still in play.
A tennis ball on the line? That’s in and a great shot.
Volleyball? Also in.
And then you have baseball and softball – where a batted ball that hits the foul line … is fair.
Know the lines and you’ll always know if you are in … or out.

Be the Referee: Field Hockey Substitution

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.
