Be the Referee: Blocking Below the Waist
November 13, 2014
This week, MHSAA assistant director Mark Uyl explains the differences between high school and the college and professional games when it comes to blocking below the waist.
"Be the Referee" is designed to help educate people on the rules of different sports, to help them better understand the art of officiating and to recruit officials. The segment can be heard on Mondays, Wednesdays and Fridays during the school year on The Drive With Jack Ebling on WVFN-AM, East Lansing.
Below is this week's segment - Blocking Below the Waist - Listen
Many times the key rules differences between high school football and those rules used at the college and profession levels deal with player safety. One of the best examples of this deals with the rules that cover blocking below the waist.
All of us have watched that game played on Saturday or Sunday; we’ve seen that wide out or the wide receiver blocking downfield, and they block the defender below the waist in springing that runner for a big gain.
At the high school level, the only offensive players that can block below the waist are those on the offensive line, generally positioned from tackle to tackle, and those blocks below the waist must be immediate – at the snap – and within that free blocking zone at the line of scrimmage.

The Michigan High School Athletic Association is accepting registrations online for game officials for the 2026-27 school year.
The MHSAA registered 9,330 officials for the 2025-26 school year, an increase of 4.9 percent from the previous year’s total.
All officials who register may sign up for up to two sports as part of their registration. Officials also will receive membership in the National Association of Sports Officials (NASO), which comes with a variety of educational and training resources and the NASO’s Shield liability insurance that will provide $6 million in coverage for officials while they are working both MHSAA and non-MHSAA events.
For new and returning officials, a $70 fee covers registration for up to two sports. Officials may register for additional sports at $16 per sport.
To avoid a $30 late fee, all fall sport registration applications must be received by Aug. 17, 2026. Winter sports registrations must be received by Nov. 16 to avoid the late fee, and spring sports registrations must be received by March 24, 2027.
Online registration can be accessed on the Officials page. More information about officials registration may be obtained by contacting the MHSAA by phone at (517) 332-5046 or by e-mail at [email protected].
New officials and those who didn’t officiate during 2025-26 must complete an officials' registration test, derived from the MHSAA Officials Guidebook, and the online MHSAA Principles of Officiating course. Additional exams must be taken by those registering for football or basketball for the first time or those who were not registered for those sports during the previous school year. Links to the Officials Guidebook, Principles of Officiating presentation and the football and basketball mechanics manuals can be found by following the “New Officials” link on the Officials page of the MHSAA Website and completing the registration process.
There also are opportunities to officiate for students at least 14 years old and in grades 9-12 through the MHSAA Legacy Program. Juniors and seniors may officiate subvarsity contests, while freshmen and sophomores may officiate contests at the middle school/junior high levels. Mentor officials will work events with Legacy participants to provide guidance and support. Find information on the Legacy Program by clicking “Officials Registration” on the Officials page of the MHSAA Website and reading under “Student Legacy Program Requirements.”
While on MHSAA.com to register for the upcoming school year, officials also can register for Officiate Michigan Day 2026, set for July 25 in Grand Rapids.
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.
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.
