Iowa coach Kirk Ferentz says the Hawkeyes feel fortunate to have played their full compliment of games.
Half of the teams in the Big Ten have had one or more games cancelled and the Hawkeyes take a 4-2 record on the road to Illinois.
After two frustrating losses to open the season the Hawkeyes have won four straight.
Ferentz says the Hawkeyes take on an Illinois team that has also improved after a slow start.
A concern is an Illinois run game that is averaging 222 yards per game.
