I haven't seen official word on this yet (though there was a supposed email sent out to certain Alumns) but Marc Morehouse has it on his blog, so that's good enough for me. When Iowa and Penn State play on October 2 in Kinnick Stadium it will be under the lights. The game is slated for roughly a 7:05 kickoff and will be on ESPN, ESPN2 or ABC.
The Iowa vs. Penn State match up the past few years has provided huge games and started building a pretty big rivalry between the schools (a one-sided rivalry as of late). If Iowa gets by Arizona and Penn State manages an upset over Alabama, this game could be huge on a national level featuring two top 10 teams. I don't think it would get Game Day (there are other big games that weekend), but is big nevertheless. Even if Penn State falls to Alabama this game could have a significant impact on the Big Ten race.
The last Iowa night game in Kinnick was against Michigan last year and it was also Homecoming. Let's hope this year's game mirrors last's with a Hawkeye victory (hopefully it won't be so cold though).
