(Radio Iowa) – Northwestern’s Pat Fitzgerald has played and coached in Kinnick Stadium but Saturday will be his first visit without the fans. After a season opening romp against Maryland the Wildcats visit an Iowa team looking to bounce back from a loss to Purdue.

Northwestern rolled up 43 points and 537 yards against Maryland but Fitzgerald says the Hawkeyes are a tougher challenge.

Fitzgerald says the Hawkeye defense causes concerns.

Fitzgerald says two fumbles and 10 penalties were the difference for the Hawkeyes at Purdue.
