Right now looking at the schedule I could see the Utah game being the only one we have gameday for. Of course there not here.
The only other currently ranked vs ranked matchup that weekend is Alabama @ Oklahoma. Which would be my guess would be who they have circled. But both those locations may have already had it by then and Utah/ISU may be a high ranked matchup for the B12 championship at that point. At this point in the season, I would say the Utah/ISU game is the second most important game that Saturday.
I would say both the KU and KSU games could be possible too, but both those Saturdays have some major games on the same day, so my guess is they are lower chances to get it.
