Mario Cristobal and the Ducks get an extra week to prepare for an unexpected top-15 matchup.

Oregon moved up three spots to No. 13 in the Associated Press poll on Sunday after beating Stanford 21-6 in the Pac-12 opener at Stanford Stadium.

The Ducks (3-1, 1-0) enter a bye week before hosting No. 15 California on Oct. 5 at Autzen Stadium.

The Bears (4-0, 1-0) moved up eight spots and are the only remaining unbeaten team from the Pac-12.

Justin Wilcox’s team has already notched road wins at then-No. 14 Washington (20-19) and Mississippi (28-20).

“I’ve watched them a little bit and saw them on TV again (Saturday),” Oregon coach Cristobal said after the Ducks ended their three-game losing streak on Saturday night against Stanford. “Excellent football team playing at a high level.”

Washington moved up five spots to No. 17 after pummeling BYU 45-19. Utah plummeted from No. 10 to No. 19 after losing at USC, which vaulted the South Division-leading Trojans (3-1, 2-0) back into the poll at No. 21.

Washington State, which was No. 19, fell out of the poll after giving up a 32-point lead in a stunning 67-63 home loss to UCLA.

Auburn, which defeated Oregon 27-21 on opening night in Arlington, Texas, moved up to No. 7 following a road win at then-No. 17 Texas A&M.

The Ducks are also No. 13 in this week’s coaches poll.
