Games that do not have a set time yet are announced 12 days prior to the game, I am about 90% certain on that (Wisconsin will be announced on Oct 11 and MSU will be announced on Oct 18).
There is a very good chance that these will both be 230 kickoffs. Here are the schedules for those weekends:
October 23- Penn State @ Minnesota TBD
Wisconsin @ Iowa TBD
Indiana @ Illinois 11 AM
MSU @ Northwestern 11 AM
Purdue @ OSU 11 AM
The 230 slot seems to be between our game and PSU/Gophers, that is a sure bet that we will get the 230 kickoff.
October 30- Northwestern @ Indiana TBD
Purdue @ Illinois TBD
MSU @ Iowa TBD
Michigan @ PSU 7 PM
OSU @ Minnesota 7 PM
Again it seems that our game is a sure bet to get the afternoon kickoff because we are clearly the best matchup left that day without a kick time announced already.
I am ready for some afternoon football in Kinnick and I do not think we will have an 11 AM kick for the whole month of October.
