Oregon's tenure in the AP Top 25 was short lived.
Following the Ducks' 37-35 loss to Arizona State Saturday night in Tempe, Oregon fell out of the latest college football rankings just a week after entering the rankings for the first time this season at No. 24.
The Ducks fell to 3-1 on the season and 0-1 in Pac-12 play.
The top five remained the same, with Alabama, Clemson, Oklahoma, Penn State and USC occupying the top spots.
In the Pac-12, Washington improved a spot to No. 6, Washington State rose two spots to No.
