No. 25 Iowa and No. 6 Wisconsin are playing for Big Ten rivalry bragging rights and a miniature statue of a bronzed bull known as the "Heartland Trophy." 

But there's another lesser known but just as important rivalry between the two schools. 

The Rusty Toolbox Game went to Wisconsin again. 

The flag football matchup between each school's student managers precedes the main event each season between the Hawkeyes and Badgers football teams. The Toolbox Tussle resumed when the series between Iowa and Wisconsin restarted in 2013.

Wisconsin's Rusty win on Friday gave the team its seventh straight win and tied the series at 11-all. The momentum carried over to Saturday when the Badgers beat Iowa 38-14 to clinch a trip to the Big Ten title game.
