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.

What's My Why: Official Robert Williams
July 1, 2026
Robert Williams, Redford
Williams officiated 52 years total through his final football season in 2023, also contributing in basketball, baseball and softball during his highly-respected run. He received the MHSAA's Vern L. Norris Leadership in Officiating Award in 2011 for his contributions not only as one of the best on the field but to mentorship and education of officials, and multiple Norris winners since have recalled his support as they were beginning their own legendary careers making the call.
My dad was a coach, so there had to be some adversity in the house. So I had to become an official, but that actually helped me.
I loved officiating because of the fact that I’m with the kids, I can give back to the game, I’m right there – best seat in the house. You see the best games whenever you officiate, because the kids are there.
It’s just helping the kids out and helping the sports that you officiate.
