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.

Be the Referee: Illegal Substitution/Participation

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 – Illegal Substitution/Participation - Listen

We’re on the football field this week with 23 players.

Twenty-three is one too many; there should only be 22 on the field at once – 11 on offense, 11 on defense.

But on this play, the offense had a 12th player lined up on the field.

What’s the call?

It depends on when the penalty is spotted.

If the officials catch it before the play is run, that’s an illegal substitution and a 5-yard penalty.

But if the ball is snapped and a play is run with 12 on the field – and the 12th player is not attempting to get off the field – then it’s illegal participation and a 15-yard penalty. It’s also a 15-yard penalty if the offense uses a substitution to create a deception.
