Iowa quarterback Mark Gronowski says the Hawkeyes know they face a big challenge on Saturday. The Hawkeyes host an 11th ranked Indiana team that is coming off a 63-10 demolition of Illinois.

Indiana’s explosive offense gets much of the attention but the Hoosier defense has given up less than nine points per game and an averaged of 87 yards of rushing.

Gronowski says he was able to watch the Indiana-Illinois game.

Gronowski says the offense is making progress and that will need to continue this week.
