First-round action begins with Cache, which has reached the state finals the last two years and won it all in 2010, taking on Weatherford at noon. Copan vs. Okay and Oklahoma Union vs. Verdigris will follow.
The semifinals and finals will be held Saturday at Chickasha.
East Central may have to forfeit
Class 5A No. 2 Tulsa East Central may have to forfeit its Sept. 21 win over Tulsa Central for using an ineligible player.
Tulsa Public Schools will make the determination of whether the Cardinals will have to forfeit the game, which East Central won 33-12, Monday morning.
The situation was first reported by the Tulsa World.
The determination will be made by TPS and not the Oklahoma Secondary School Activities Association because the game involved two TPS schools and is a district eligibility matter.
