Iowa Hawkeyes Playing At Wrigley Field This Year

I'm confused. I didn't know you could play football in a baseball stadium, no matter how iconic the stadium to be. It was announced today that the Iowa Hawkeyes football team will be facing off against Northwestern at Wrigley Field in Chicago. The game has been scheduled for November 4th in Chicago. There is no ticket information available yet. According to KCCI, a release from Northwestern revealed that Northwester season ticket holders will have priority in purchasing tickets for this game.
