October 15, 2015
This week, MHSAA assistant director Mark Uyl explains the difference between high school and college/pro rules when it comes to intentional grounding.
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 - Make the Call: Intentional Grounding - Listen
A QB is rolling out wide toward the sideline and is being chased by two large defenders. To avoid a certain sack, the QB throws the ball away deep down the field where no offensive receiver is even in the same zip code of where the ball hits the ground.
What’s the call?
Under high school rules, this is intentional grounding as there always has to be a receiver in the general area of the pass. At the college and pro levels, all the QB has to do is throw the ball beyond the line of scrimmage if he has scrambled outside of the tackle box. When at your next game, know this important difference when it comes to intentional grounding.
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.
