Is there a quarterback controversy now in Iowa City? Sophomore Alex Padilla replaced Spencer Petras on the fourth drive of a 17-12 win at Northwestern and led the Hawkeyes to a pair of first-half touchdown drives. Ferentz says Petras was nursing an injury suffered at Wisconsin.

He also says he is not ready to name a starter for the upcoming clash with Minnesota.

The Hawkeyes are 7-2 and remained 19th in the latest AP Poll.
