Iowa coach Kirk Ferentz says quarterbacks Cade McNamara and Brendan Sullivan are both doing well in practice, but Ferentz is not making a quarterback change for Saturday’s game against Northwestern.

Ferentz says he has confidence in Sullivan, who transferred to Iowa from Northwestern, but McNamara is the starter.

Ferentz says the Hawkeye offense and defense have to focus on the details of what went wrong at Michigan State as they prepare for this week’s game against Northwestern.

Ferentz says the team’s defensive miscues are uncharacteristic. The Hawkeyes current rank 83rd in pass yards allowed per game.

Saturday’s Iowa-Northwestern game in Iowa City is scheduled to start at 2:30.
