For the first time in 10 years, Texas fell out of the Top 25 ranked teams in The Associated Press college football poll.
Meanwhile, after running away from Stanford, Oregon jumped over Boise State and into No. 3. Two more traditional powers tumbled from the rankings, too, with Penn State and Southern California joining the Longhorns in the others receiving votes.
The top two spots in the rankings remained unchanged: Alabama is No. 1 and Ohio State is No. 2, just the way it's been since the preseason.
No. 4 Boise State spent the entire first month of the season ranked third, but the Broncos couldn't hold off the Ducks this week.
Fort Worth's own TCU was No. 5 in the latest poll. The top five in the USA Today coaches' poll was the same as the AP's top five.
But the Longhorns lost their second straight game Saturday, 28-20 to Oklahoma, leaving them unranked for the first time since Oct. 15, 2000. Their streak of 162 consecutive weeks in the rankings was the longest active streak in the country.
Ohio State now has the longest streak at 90 straight poll appearances. Florida is second at 87 straight.
Texas hasn't lost three straight games since closing the 1999 season that way. The Longhorns have a week off before visiting Nebraska.
"We have two weeks of work," linebacker Eddie Jones said. "Work hard as a team, stay up, stay motivated and keep this heart and drive that we had today. We can go back out and win. We can change things around here."
