The first week of the high school football season is always exciting … and sometimes confusing. Here are some – not all – differences between the high school game and what you see on Saturdays and Sundays.
In high school, there is no such thing as an uncatchable ball when judging pass interference. It is a penalty if there is illegal contact, whether the ball is catchable or not.
In overtime, high school teams start with the ball at the 10-year line – not the 25 like in college. And in high school overtime, you are only able to get a first down via penalty. And, at no time is a high school team required to go for two points.
And on extra point plays, if the defense gains possession, the try is over. The defense cannot return the ball for two points.

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.
