This week, MHSAA officials coordinator Sam Davis explains the differences in high school pass interference rules from those at the college and pro levels.

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 – Pass Interference – Listen 

One of the big differences between high school football and the college or pro game is how pass interference is called.

In high school, there is no such thing as an “uncatchable” pass. If there is illegal contact by the defender while the ball is in the air, that’s pass interference, no matter where the pass ultimately ends up.

Also – in high school – a defender can “face guard” as long as no contact is made with the receiver. That is not pass interference, even if the defender does not look back for the ball. 

Both of those interpretations differ from the college and pro game. Both (of those) levels have an uncatchable exception, and neither allows for face guarding. 

Keep that in mind the next time you think you’ve spotted pass interference at the high school level.

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.
