After another win, the Ducks remain in the second spot in the College Football Playoff rankings.
The latest rankings announced Tuesday remain unchanged at the top, with Alabama first, Oregon second, Florida State third and Mississippi State fourth.
The Ducks are coming off a 44-10 trouncing of the Colorado Buffaloes on Saturday, in what may have been Heisman hopeful Marcus Mariota's last game at Autzen Stadium.
Mariota left the field, after throwing three touchdowns and running for an additional score, to the crowd chanting "Mar-i-o-ta!"
Mariota is expected by many experts to enter the NFL draft following the college football season.
