A Leading Official
July 29, 2014
For more than a decade, Mark Uyl has been the MHSAA’s leader of service and support to officials. Mark’s calm demeanor and subtle sense of humor have much to do with his successful leadership of what we sometimes call “the complaint department;” but because he has been both, Mark has a good feel for and the respect of both school administrators and officials.
Since joining the MHSAA staff in January of 2004, Mark has continued to referee college football and baseball. Last month Mark worked the NCAA College World Series in Omaha which had been a long-time goal for this still very young man.
This week Mark ascends to chair of the board of directors of the National Association of Sports Officials (NASO).
It’s clear that Mark has as fine a reputation nationwide as he enjoys here in his home state.
Be the Referee: Volleyball Libero Uniforms

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 – Volleyball Libero Uniforms - Listen
Before the match begins, a volleyball team takes the court wearing super-stylish, brand-new jerseys. The libero is in a bright neon top, but two other teammates also have the same neon sleeves.
At first glance, it looks like multiple liberos are on the floor. As the referee, you must check carefully: Under current NFHS uniform rules, the libero’s jersey must clearly contrast from all other teammates in color, design, and trim.
Accessories like sleeves or leggings are permitted, but they cannot confuse the identification of the libero. In this case, because the libero’s jersey color is the same as teammates’ sleeve color, the contrast is not sufficient, and the coach must correct it before play begins.
This ensures quick identification for substitutions, scoring, and libero actions.
