IOWA CITY, Iowa (AP) — Iowa plans to wear throwback uniforms from the 1920s during next season’s home opener against Iowa State.  The Hawkeyes will wear uniforms resembling those of their 1921-22 teams, which both went 7-0.  Iowa will wear gold helmets with gray facemasks and gold pants.  The jerseys will be black with white numbers and no names, and the Hawkeyes will also wear black socks and shoes.  The Kinnick Stadium opener on Sept. 8 will mark just the third time Iowa has worn throwback uniforms.
