Oregon led the Pac-12 at No. 5 in the latest BCS standings, but the Ducks and the conference have no chance to play for the national title.
Stanford, which ended Oregon's national title hopes with a win in Eugene on Nov. 17, is eighth. Oregon State is 15th and UCLA is 16th.
Stanford plays host to UCLA on Friday in the Pac-12 championship game. The winner goes to the Rose Bowl.
Oregon is a likely at-large selection for a BCS bowl, most likely the Fiesta Bowl against the Big 12 champion.
The BCS national title game will match unbeaten, top-ranked Notre Dame against the once-beaten SEC champion, which will be decided on Saturday when No. 3 Georgia plays No. 2 Alabama.
