Oklahoma State dropped out of The Associated Press college football poll after a controversial loss, and Georgia and Clemson fell after close calls against lightly regarded opposition.

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 Football Championship Subdivision-level Nicholls by two.

The Cowboys were ranked 22nd when it lost, 30-27, to Central Michigan on a final-play touchdown Saturday. Officials acknowledged after the game that they misinterpreted a rule, and the play should not have been granted. Oklahoma State was a three-touchdown favorite against the Chippewas.

Here are some other takeaways from the poll.

No. 10 Louisville is in the top 10 for the first time since October 2013, just in time to host one of the biggest games in school history. Florida State plays at Louisville on Saturday.

No. 24 Arkansas is ranked for the first time this season after beating TCU on the road, 41-38, in double overtime. The Razorbacks are ranked for the first time since early last season.

No. 23 Florida is back in the rankings after slipping out after the opening weekend.

TCU is unranked for the first time since September 2014.

Officials suspended for incorrect call: The eight-man officiating crew that botched the end of the Central Michigan-Oklahoma State game has been suspended for two games, the Mid-American Conference announced.

The Big 12 Conference announced that the two-person video replay crew that worked the game also has been suspended for two games. In addition, the replay crew will be prohibited from working postseason games this season.

“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,” Big 12 coordinator of officials Walt Anderson said in a statement. “NCAA rules permit instant replay to correct egregious errors and it is unacceptable that it did not occur in this situation.”

Officials mistakenly gave the Chippewas (2-0) an untimed final play from midfield after the Cowboys (1-1) were penalized for intentional grounding while trying to run off the last four seconds with a three-point lead.

On that play, Central Michigan scored a touchdown on a long pass and lateral to win, 30-27. The referee acknowledged afterward that an error was made by extending the game after a loss-of-down penalty.

“After a thorough review and evaluation of the entire Central Michigan at Oklahoma State contest, we have decided to suspend the officiating crew for the next two consecutive weeks,” Bill Carollo, national coordinator of college football officials, said in statement released by the MAC.

Oklahoma State athletic director Mike Holder voiced his protest, but the result of the game was final.

Big Ten teams avoid nonconference hiccups: Wisconsin badgered Akron. Michigan manhandled Central Florida. Iowa overwhelmed Iowa State.

With Big Ten play looming in a couple of weeks, the conference's top teams took advantage of what on paper at least looked like weaker Week 2 opponents.

These wins are by no means automatic for power-conference schools. Just ask Oklahoma State.

Clemson and Georgia had some nervous moments, too.

“These are limited opportunities you get, and I think you've got to learn to appreciate each opportunity,” Wisconsin coach Paul Chyrst said Saturday. “All we've got to focus on is ourselves and maximize each opportunity.”

Chryst had his team focused and ready. The Badgers led 30-10 at halftime on the way to a 44-point rout of the Zips.

Ohio State got off to what would be considered a sluggish start for the Buckeyes in a 48-3 win over Tulsa. Ohio State didn't score an offensive touchdown until quarterback J.T. Barrett rushed in for a score with 9:42 left in the third quarter.

“But good teams pick up each other,” coach Urban Meyer said.

The Buckeyes defense is in midseason form after intercepting four passes, including two pick-sixes.

Week 3 promises to be a bit more challenging for the Buckeyes, who will face No. 14 Oklahoma and quarterback Baker Mayfield on the road.

“Obviously, the challenge will come next week against a very good team, and we're going to jump on that one early and get ready to go” Meyer said.

Wisconsin has already passed its big nonconference test after defeating then-No. 5 LSU at Lambeau Field in the season opener. So for the Badgers, the two weeks between the Tigers and their Big Ten opener on Sept. 24 against Michigan State are about building momentum and keeping a chip on their collective shoulders.

“We didn't want to show that we were too excited and thinking about [LSU]. We wanted to go and move on to Akron, and we're going to do the same thing next week here,” Wisconsin outside linebacker T.J. Watt said.

Ohio State moved up one spot to No. 3 in AP Top 25 poll. Wisconsin moved up a spot to ninth. The Badgers play winless Georgia State in Week 3.
