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: 40-Second Play Clock

August 29, 2019

This week, MHSAA Assistant Director Brent Rice explains the change in football to a 40-second play clock.

Below is this week's segment - 40-Second Play Clock - Listen

One of the rules changes in high school football this year involves timing between downs.

All varsity games will be played with a 40-second play clock that begins after the conclusion of the previous play, with exceptions for things like timeouts, penalties, measurements and at the start of a period – when a 25-second count will be used.

In experiments in Michigan over the past few seasons, the 40-second play clock proved to improve the pace of play and consistency between plays because it is not dependent on the referee’s subjective signal. And while some schools may choose to purchase visible play clocks for their fields, it is not required. The Back Judge, who has the primary responsibility for the play clock, will signal at 10 seconds and count the last five seconds.
