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 – Fifth-Quarter/Third-Half Rule - Listen

Did you know? ... Many sports now offer student-athletes the opportunity to compete on both varsity and subvarsity teams during the same week or even the same day.

The Fifth-Quarter or Third-Half Rule was instituted to help subvarsity teams with low participation numbers. Now, a student-athlete on the varsity team can participate in part of the JV game – so each level of team can play with a safer number of players.

For example, a football player who plays in three quarters of the JV game may also play in two quarters of the varsity game – for a total of five quarters played.

The rule is not designed for high-caliber players to play down a level and dominate games or pad stats.

The Fifth Quarter is available in basketball, football, and boys lacrosse – Soccer has the Third-Half Rule.

Be the Referee: Illegal Substitution/Participation

By Paige Winne

November 11, 2025

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.
