BROOKLYN CENTER, Minn — The governing board of the Minnesota State High School League approved girls wrestling provisionally as an interscholastic sport. The decision gives organizing schools as many as five years to demonstrate stability prospects and logistics. Meanwhile the Minnesota Wrestling Coaches Association is continuing on its own with schools that include Chatfield. On the issue of girls flag football, the State High School League delayed action until organizers, which include the Minnesota Vikings, develop rules and a system of scheduling games.
