The MHSAA has adopted the national replay rule that will be used at the scholastic level for the first time in the 2009-10 season. The rule, however, will only be applied during state tournament games. It allows referees or replay officials to decide if a made field goal at the end of the fourth quarter or overtime went in before the final buzzer, and/or to determine if the made basket was a two- or three-point field goal. The replay rule does not apply to baskets made at the end of the first, second or third quarters, nor can it be used for regular season games.
Some MHSAA member schools have red or LED lights on top of their backboards that, along with a buzzer, signify the end of a quarter. For the first time, the MHSAA will allow these lights to be used to officially signal the end of a period or overtime. In the event these lights are not present, the end of quarters or overtimes will continue to be signaled solely by the automated buzzer.
Along with the new rules, the MHSAA has made a few clarifications to its previous guidelines. One of these clarifications states that any item that a referee determines to be a safety concern will not be permitted. This includes jewelry or protective gear worn by players. The referee may make such a judgment at any time during the course of a game, or as early as 15 minutes before the game.
Free-Throw Lane Rules
Another clarification to the 2009-10 MHSAA rule book involves the free-throw lane, or more specifically, the sides of the lane occupied by players other than the shooter. The clarification states that a player has left his marked space (36-by-36 inches) as soon as he contacts any part of the area outside the space. This is considered a violation if the free-throw shooter has been handed the ball by the referee. Also, the MHSAA clarified that a player along the outside of the free-throw lane must have one foot "positioned near the outer edge of the lane." The other foot can be anywhere within the 36-by-36-inch area.
