The Top 25 was shaken Sunday after seven ranked teams lost, including five to teams that were unranked or lower ranked. Stanford dropped eight spots and Michigan fell from the poll.
The top four was unchanged, with No. 1 Alabama receiving 55 of 60 first-place votes. No. 2 is Oregon, followed by Clemson and Ohio State. Florida State moved up to No. 5 to set up a top-five matchup at Clemson next week.
Stanford, which had been top-five all season, lost 27-20 at Utah and dropped eight spots to No. 13. The Cardinal's Pac-12 and national title hopes took a serious hit, though they'll be able to get right back in the conversation next week by beating No. 9 UCLA at home.
No. 24 Auburn moved into the rankings for the first time this season to join No. 6 LSU, No. 7 Texas A&M, No. 11 South Carolina, No. 14 Missouri, No. 15 Georgia and No. 22 Florida from the SEC.
Missouri (6-0) jumped 11 spots with its first statement victory since joining the SEC, a 41-26 win against banged-up Georgia. But the Tigers lost quarterback James Franklin to a separated throwing shoulder. The senior will miss the rest of the regular season, a source told ESPN's Brett McMurphy on Saturday. Franklin's replacement is Maty Mauk, a redshirt freshman and big-time recruit.
The record for most teams from one conference in a regular-season poll had been seven, done many times, including this season by the SEC. The ACC and Big Ten have also reached seven ranked teams in season.
The SEC also had eight teams ranked in the 2011 preseason poll.
No. 12 Baylor is the highest ranked team in the Big 12 for the first time since the league started in 1996, taking advantage of Oklahoma's surprising loss to Texas. The Sooners fell six spots to No. 18.
