Summer Football Safety
July 23, 2018
(This blog first appeared on MHSAA.com on June 23, 2017.)
Across the U.S. this summer, school-age football players are flocking to camps conducted by colleges and commercial interests. They get outfitted in full gear and launch themselves into drills and skills work.
Unlike the start of the interscholastic football season, the players usually do this without several days of acclimatization to avoid heat illness, and without limits on player-to-player contact to reduce head injuries.
Required precautions of the school season are generally ignored at non-school summer camps.
One notable exception to this foolish behavior is found in Michigan where the Michigan High School Athletic Association prohibits member schools’ student-athletes from using full equipment and participating in full-contact activities outside the high school football season. This is not a recent change; it’s been the MHSAA’s explicit policy for more than four decades.
And it’s a policy that has never been more in style and in favor than it is today.
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.
