The rarer the play, the more exciting the finish, of course. We witnessed that Saturday night at Kinnick Stadium.

Iowa kicker Marshall Koehn booted a 57-yard field goal as time expired to lift the Hawkeyes to a 27-24 victory over previously undefeated Pittsburgh, coached by former Michigan State defensive coordinator Pat Narduzzi.

It was a great night for Koehn, obviously, who also connected on a 43-yard field goal to get the scoring started and hit three extra points

With the win, Iowa improved to 3-0 and faces North Texas next Saturday in its final tuneup before Big Ten play.
