NCAA Football Rankings, Week 6: Northwestern joins Ohio State as only Big Ten teams in poll

The Big Ten's Northwestern Wildcats entered the Associated Press Top 25 Poll with a victory over the Indiana Hoosiers that earned Pat Fitzgerald's team the No. 24 spot in the rankings. It is the first poll appearance for Northwestern since 2008, and at 5-0, the Wildcats join the Ohio State Buckeyes as the only undefeated and ranked teams in the Big Ten to make the AP poll.

The Buckeyes' victory over the Michigan State dropped the Spartans out of the poll and obviously the Minnesota Golden Gophers are still unranked -- though even moreso after Saturday afternoon's loss to the Iowa Hawkeyes.

The Pac-12's No. 23 Washington Huskies and No. 25 UCLA Bruins were the other two teams to enter the AP poll this week. Stanford's' loss to the Huskies was the only major change in the poll as the Cardinal fell 10 spots from last week's No. 8 ranking.

The Alabama Crimson Tide unanimously found themselves atop the Associated Press Top 25 Poll, earning all 60 first-place votes after the team's victory over Ole Miss on Saturday. In the top five, the Florida State Seminoles leaped the LSU Tigers for the third spot. The Oregon Ducks remained in second while LSU came in No. 4 and the Georgia Bulldogs retained the No. 5 slot.
