Oklahoma State dropped out of The Associated college football poll after a controversial loss, and Georgia and Clemson fell after close calls against lightly regarded opposition.
Also on Sunday, Big 12 football coordinator of officials Walt Anderson announced a two-game suspension of the two-person instant replay crew that worked Saturday's Central Michigan at Oklahoma State game.
"The crew missed an opportunity to advise the MAC officiating crew of the misapplication of the penalty giving CMU an untimed down that resulted in its game-winning touchdown," he said. "NCAA rules permit instant replay to correct egregious errors and it is unacceptable that it did not occur in this situation. Additionally, this replay crew will not be eligible for assignment to an end-of-season bowl game."
Alabama is still No. 1, receiving 56 out of 61 first-place votes Sunday. No. 2 Florida State, No. 3 Ohio State and No. 4 Michigan all moved up one spot. The Seminoles got four first-place votes and Michigan received one.
Clemson fell from second to fifth after a four-point win against Troy. No. 16 Georgia dropped seven spots after beating FCS Nicholls by two.
Oklahoma State was ranked 22nd when it lost 30-27 to Central Michigan on a final play touchdown Saturday. Officials admitted after the game they misinterpreted a rule, and the play should not have been granted. The Cowboys were three-touchdown favorites against Central Michigan.
Oklahoma held at 14.
