Below is this week's segment – Pass Interference - Listen

How well do you know the rules regarding pass interference and passes behind the line of scrimmage? Let’s find out.

The blue team has the ball. The quarterback throws a forward pass to a receiver who is positioned behind the line of scrimmage. Before the receiver can make the catch, a red team defender makes contact with him, and the pass falls incomplete.

Is this defensive pass interference?

The answer is no.

Under high school football rules, pass interference restrictions only apply to forward passes that cross the line of scrimmage. Because this pass was thrown to a receiver behind the line of scrimmage and did not cross it, there is no pass interference.

The same rule applies to backward passes. Pass interference cannot be called on a backward pass, regardless of where the receiver is positioned.

Be the Referee: Illegal Substitution/Participation

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.
