Doors open at 7:30 a.m., with the first session at 9 a.m. at DeVos Place. The day-long event will feature dynamic speakers and presenters providing knowledge in several sports and all levels including collegiate and professional. We will be highlighting several of those speakers over the next many weeks on MHSAA.com and social media as part of the lead-up to the event.
Cost is $45 if officials register by the end of June, and $50 beginning July 1. More information is on the way; keep posted at MHSAA.com/OMD.
This will be the third Officiate Michigan Day, joining events in 2013 and 2018.
OMD will accompany the annual National Association of Sports Officials (NASO) Summit that will take place July 26-28, also at DeVos Place.
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.
