According to legend, they assumed that nickname upon acquiring some reddish hand-me-down jerseys from the University of Chicago football team, the Maroons.
The Cardinals joined the new American Professional Football Association (soon renamed to what is now the National Football League) and continued to use Normal Park as their home field for several years and continued to be called the Racine Cardinals for a while.
They changed their name again, to "Chicago Cardinals", to avoid confusion after the National Football League fielded a team in Racine, Wisconsin.
On the eastern portion of the site along Racine sits a Chicago Police Department facility which was built in 1952.
[1] The western portion of the site is occupied by single family homes built on a cul-de-sac where the field once was.
