Oklahoma dropped out of The Associated Press college football poll for the first time since September 2016 and No. 24 Iowa State jumped back into the Top 25 after a day of upsets.

The 22nd-ranked Longhorns managed to hold on to a spot in the rankings, falling 13 spots after losing at home to TCU.

This season, it took one massive win against the defending AAC champions to convince voters that the 4-0 Mustangs were among
