At the finals, there are always 6 officials in uniform, although only a 5 man crew works the game. The alternate is used if anyone goes down during the game. The alternate also serves as the 6th official on any scoring kicks, going under the crossbar with the back judge, so that both wing officials can maintain their positions on the line of scrimmage. For the first time this year, the IHSAA mandated the use of an alternate at the Regionals and Semistate, in addition to the State Finals. Also, for the first time this year, the crews are allowed to choose their own alternate (within limitations). Previously, the crew was stuck with whomever the IHSAA decided to designate as the alternate official. The present system is a big improvement. True story: I worked the Penn - Warren Central final in 2003, and my linesman went down late in the first quarter with a pulled hamstring. We had to work 3/4 of the game with the alternate official, whom we had laid eyes on for the first time about an hour before kickoff. Fortunately (or unfortunately, depending on your point of view), the game was not close.
