AP Top 25 poll: Texas reclaims No. 1, Alabama falls, Oregon joins top three in college football rankings

Texas will enter this week's Red River Showdown with Oklahoma as the nation's No. 1 team after the Longhorns claimed the top spot in the AP poll on Sunday following Alabama's Week 6 loss to Vanderbilt . The Crimson Tide had been No. 1 but fell to No. 7 following their stumble against the Commodores.

The Longhorns -- off Saturday -- benefitted from the carnage of a wild week that saw five of the top-11 teams lose. Ohio State crept up one spot to No. 2 following its 35-7 win over Iowa and received nine first-place votes compared to the 52 first-place votes awarded to the Longhorns.

This isn't Texas' first time at No. 1 this season. The Longhorns ascended to No. 1 following an authoritative Week 2 win at Michigan and held the spot for two weeks. They slipped to No. 2 last week, however, as the Crimson Tide claimed the top spot after a Week 5 win over Georgia .

Though Texas rose, it was a rough week for other highly ranked SEC teams such as the Crimson Tide, Tennessee and Missouri . As a result, the Big Ten's top teams came out of the wild weekend in excellent shape as Ohio State, Oregon and Penn State each registered as top-five teams in the new poll. Oregon's climb to No. 3 means that it will officially be a top-three battle when the Ducks host the Buckeyes in a marquee Week 7 showdown.
