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.

Below is this week's segment – Tennis Nets - Listen
Let’s talk tennis… specifically, the rules around the net.
First – tennis nets are 42 inches high at the posts and 36 inches high in the center. And nets measure 42 feet wide.
Players and their equipment CANNOT touch the net during a point. However, a player’s follow-through can cross over the net if the ball was hit to the correct side of the court. But no part of the follow-through can touch the net.
Also, the ball must completely cross the net before it can be hit. If your opponent hits a high lob and you are standing at the net ready to smash a return – you must wait until the ball is completely over the net before hitting it.
Making contact with the net during play or hitting the ball before it’s over the net results in a loss of point.
