NEW YORK (AP) -- LSU was a unanimous No. 1 in The Associated Press college football poll, marking the first time since 2008 a team has received all the first-place votes during the regular season.
The Tigers (10-0), who have been No. 1 since Sept. 25, received all 60 first-place votes from the media panel in the rankings released Sunday. The last unanimous top-ranked team in the regular season was Texas on Oct. 26, 2008.
Oklahoma State (10-0) was No. 2 for the second straight week, but the rest of the top five was scrambled a bit after Boise State and Stanford lost for the first time.
Alabama moved up to No. 3, Oregon jumped two spots to No. 4 and Oklahoma moved to No. 5.
The top five teams in the BCS standings released later Sunday, which use the Harris poll and the coaches' poll, were the same as the top five in the AP poll
LSU had been sharing first-place votes for the last month and a half with Alabama, Oklahoma and Boise State. But as those teams each took a loss, the Tigers picked up support.
Boise State was the only team other than LSU receiving a first-place vote last week, but after TCU upset the Broncos 36-35 at home on Saturday, the Tigers made a clean sweep.
No. 8 Stanford, which lost 53-30 at home to Oregon, and No. 10 Boise State each fell five spots this week.
The rest of the top 10 had Arkansas at No. 6, Clemson at No. 7 and Virginia Tech at No. 9.
The only other undefeated major college team, Houston from Conference USA, was No. 11.
No. 21 Penn State fell nine spots after it lost its first game following the firing of coach Joe Paterno, 17-14 at home to No. 17 Nebraska.
Four teams dropped out of the rankings after losses: Cincinnati, Auburn, Texas and Georgia Tech.
Cincinnati dropping out leaves the Big East with no ranked teams this week.
The teams entering the rankings this week were No. 19 TCU, No. 23 Florida State, No. 24 Notre Dame and No. 25 Baylor.
All had been previously ranked earlier in the season.
Michigan State is No. 12, followed by Georgia, South Carolina and Wisconsin.
No. 16 Kansas State, Nebraska, Southern California, TCU and Michigan round out the top 20.
Penn State and No. 22 Southern Miss are in the final five, along with three of the newcomers.
The Big Ten and SEC have the most ranked teams with five each.
