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.

Be the Referee: Fixed Obstruction in Tennis

Below is this week's segment – Fixed Obstruction in Tennis - Listen

We’re playing tennis today and due to the rain outside, we’ve moved our match to an indoor court. In the second set, after a couple of volleys, I’m forced to retreat to the back line and hit a high lob shot. Too high in fact … as the ball hits the ceiling and then comes down on my opponent’s side of the net.

What should happen next?

Should my opponent play the ball as they normally would? My shot landed on their side, so it doesn’t matter if it hit the ceiling?

Or, do I lose a point because my shot hit the ceiling?

In tennis, if a ball touches a permanent fixture, like the ceiling, before hitting the proper court, the player who hit the ball loses the point.

In this case, I lose the point since it was my shot hitting the ceiling.
