The tradition, started in 1962, is for the Michigan Wolverines football players to leap and touch a maize-and-blue banner as they run onto the field before home games.
The banner, reading "Go Blue: M Club Supports You", is raised at midfield before every Michigan home game.
According to another account, Michigan hockey coach Al Renfrew asked his wife, Marguerite, to make two banners to drape over the football locker room.
[3] During The Ten Year War, the M Club banner was the focus of two incidents involving the Ohio State Buckeyes.
In 1973, the Ohio State players ran onto the field first and, led by Outland Trophy winner John Hicks, unsuccessfully attempted to destroy the banner.
