Oklahoma, LSU Top College Football Rankings

Oklahoma held on to its spot at No. 1 while LSU moved up to No. 2 in the most recent Associated Press Top 25 poll.

After defeating Oregon in the most anticipated game of the weekend, LSU got a bump up ahead of No. 3 Alabama in this week's poll.

Oklahoma checked in with 32 of 60 first-place votes, LSU had 17 votes, Alabama had nine votes, and No.4 Boise State had two.

Rounding out the Top 10 were No. 5 Florida State, No. 6 Stanford, No. 7 Texas A&M, No. 8 Wisconsin, No. 9 Oklahoma State, and No. 10 Nebraska.

Oregon -- who made it to the national championship game in 2010 -- dropped nine spots to No. 13 after losing 40-27 on Saturday night. The other participant of that game, defending national champion Auburn, dropped out of the rankings altogether despite winning its game on Saturday.

Auburn narrowly defeated Utah State 42-38 and fell from its spot at No. 23 out of the Top 25. According to the Associated Press, Auburn becomes just the second defending champion since 1950 to fall out of the rankings after the first week of the season.

Notre Dame, Georgia, and Southern California also dropped out of the rankings after the first week of games. Notre Dame, initially ranked No. 16, lost to South Florida 23-20; Georgia lost to No. 4 Boise State 35-21; and USC dropped out despite defeating Minnesota 19-17.
