The Red Raiders jumped four spots and past No. 3 Penn State to No. 2. The unbeaten Nittany Lions were idle.
No. 4 Florida moved up one place after its 49-10 rout of Georgia, and Texas dropped four spots to No. 5.
The Crimson Tide, which beat Arkansas State 35-0, received 46 of a possible 65 first-place votes from the media panel and 1,600 points. Texas Tech got 12 first-place votes and 1,528 points, and Penn State had six and 1,525. The Gators received the other No. 1 vote.
The top spot in the poll hasn't been held by this many teams since 1990, when Miami, Notre Dame, Colorado, Michigan and Virginia all had a turn at No 1.
Georgia started this season No. 1 and was replaced by Southern California after the opening week.
USC lasted four weeks before being upset by Oregon State, and Oklahoma took the top spot. The Sooners were No. 1 for two weeks, then lost to Texas, which held the top spot for three weeks.
Alabama hasn't been No. 1 since finishing that way after the 1992 season, the last of the Crimson Tide's six AP national championships.
Alabama's first game as a No. 1 team will be Saturday at Louisiana State. Tide Coach Nick Saban will be coaching in Baton Rouge for the first time since he left the Tigers for the NFL after the 2004 season. Saban led LSU to a BCS national title in 2003.
Penn State next plays at Iowa.
