NEW YORK -- Welcome back, Georgia and Georgia Tech.
See ya down the road, Clemson and Kansas State.
Clemson and Kansas State tumbled in The Associated Press Top 25 College Football Poll on Sunday after losing for the first time this season, and the top five teams in the rankings held their ground heading into the showdown between No. 1 LSU and No. 2 Alabama.
Georgia, meanwhile, climbed four spots to No. 18 after beating Florida, 24-20, The Bulldogs also moved up to No. 20 in the USA Today Top 25 and the Harris polls.
Georgia Tech, which was ranked as high as 12th two weeks ago before losing to Virginia and Miami, reemerged this week at No. 22 in The AP, No. 23 in the USA Today poll and No. 21 in the Harris Top 25.
Clemson slipped five spots after losing 31-17 at Georgia Tech and Kansas fell seven spots to No. 17 after getting thumped 58-17 by Oklahoma.
LSU received 47 first-place votes from the media panel, Alabama had 10 and No. 5 Boise State had one.
No. 3 Oklahoma State and No. 4 Stanford held on to their spots after victories, while the Broncos were idle.
Auburn jumped back in at No. 25.
The losses by Clemson and Kansas State leave six undefeated teams in major college football -- the top five and No. 14 Houston.
The rest of the top had Oregon at No. 6, Oklahoma moving up four spots to No. 7, Arkansas at No. 8 and Nebraska and South Carolina right behind.
Clemson at 11th was followed by Atlantic Coast Conference rival Virginia Tech.
Michigan is No. 13, its best ranking since Nov. 4, 2007.
Michigan State is No. 15, followed By Penn State, Kansas State, Georgia, Wisconsin and Arizona State.
The final five were Southern California, Georgia Tech, Cincinnati, West Virginia and Auburn.
The defending national champion Tigers have fallen out of the rankings three times this season, only to work their way back in.
Falling out after losses were two Big 12 teams.
Texas A&M (5-3) was upset at home 38-31 in overtime by Missouri and is unranked for the first time this season.
Texas Tech moved into the rankings last week for the first time this season by beating Oklahoma. The Red Raiders followed that up with a 41-7 loss at home to Iowa State and are unranked again.
OKLAHOMA STATE HAS CLEAR PATH TO BCS TITLE GAME:
New BCS rankings come out Sunday as No. 1 LSU, No. 2 Alabama remain intact
Stanford's first win of the season against a ranked team helped Andrew Luck and the Cardinal move up in the BCS standings.
While LSU (8-0), Alabama (8-0) and Oklahoma State (8-0) remained locked into the top three spots in the standings released Sunday, Stanford moved up two places to fourth after beating Southern California 56-48 in triple overtime.
Boise State (7-0) slipped a spot to fifth, while Clemson (7-1) fell from fifth to 11th after its first loss.
LSU and Alabama will play Saturday in Tuscaloosa, Ala., for first place and the inside track to the BCS national championship game.
Oklahoma State seems to be in position to win out and reach the title game in New Orleans on Jan. 9. The computer ratings have the Cowboys No. 1.
The BCS standings use the Harris poll, the coaches' poll and computer ratings to determine which teams play for the national championship.
LSU is No. 1 in both polls and Alabama is No. 2 in each. The Tigers and Crimson Tide are tied for the second-best computer rating.
Oklahoma State is No. 3 in the Harris poll and No. 4 in the coaches' poll, and Stanford is No. 4 and No. 3. But the difference between the Cowboys (.9310 BCS average) and the Cardinal (.8615) is the computer ratings.
Stanford is sixth in the computers because of a weak early season schedule. The Cardinal should be getting a boost from here on out.
After a road game Saturday against Pac-12 rival Oregon State, the Cardinal play Oregon, eighth in the BCS standings, at home. They finish with California and Notre Dame at home, and could play in the Pac-12 championship, too -- probably against Arizona State.
It might not be enough to catch Oklahoma State. The Cowboys face Big 12 rival Kansas State, 14th in the BCS standings, on Saturday, have road games against Texas Tech and Iowa State, and finish with a home game against Oklahoma.
The Big 12 no longer has a championship game.
For Boise State, the formula is the same as it has always been. The Broncos' conference schedule -- this year in the Mountain West -- presents few stiff challenges, so Boise State probably needs to go undefeated just to play in one of the four marquee bowl games. The Broncos have done that twice. To reach the national championship game for the first time, Boise State will need the teams ahead of it to lose.
