On 9/14, networks will be able to select games for Week Four using the 12 day selection process. Networks can choose games as little as six days in advance, negotiated with individual conferences in terms of how many times they can do it during a season.
Generally, the networks won't waste those six day exceptions early in the season. Here's my guesses
3:30pm: Oklahoma at Cincinnati, Bowling Green at Michigan
8pm: UCLA at Texas, Oregon St. at Boise St.
Arkansas at Alabama, 3:30pm
12pm: Ball St. at Iowa
