Below is this week's segment – Coaches Responsible for Equipment - Listen

Over the past decade, just about all new playing rules have tended to focus on improving the health and safety of those playing the game. In all sports, it’s the responsibility of the head coach to make sure that his or her players are properly equipped according to the rules of the game.

It’s generally one of the first things the official will ask the head coach before play begins. This can cover everything from bats in baseball and softball, to helmets and face masks in football or ice hockey, or to those sports where mouth guards are required. This is to ensure that each school and the head coach is taking responsibility when it comes to the equipment being worn and keeping those playing the game safe.

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.
