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.

Be the Referee: Football Review

November 21, 2019

This week, MHSAA officials coordinator Sam Davis explains how video will be used for the first time at this season's MHSAA Football Finals. 

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 - Football Video Review - Listen

For the first time this year, video review of potential scoring plays and potential turnovers will take place at the MHSAA Football Finals at Ford Field for the 11-player games.

Under this system, any play which may or may not result in points being scored or any play which may or may not have resulted in a turnover can be reviewed. Personnel in the press box will look at all such plays and contact the referee on the field if a review takes place – and they give the final determination to the crew on the field.


Review may not be initiated by the officiating crew nor by the head coach of either team. Football joins basketball and ice hockey as sports where limited video review may now take place.
