Utah moved up two spots to No. 15 in both college football polls Sunday, setting up a potentially high-profile matchup with No. 18 Arizona State in the Pac-12 South in two weeks.

The Sun Devils will come to Rice-Eccles Stadium on Oct. 19. First, though, the Utes (4-1) will play at Oregon State on Saturday, while ASU (4-1) hosts Washington State.

Utah was idle this weekend. The Utes profited from losses by Washington at Stanford and by Iowa at Michigan, moving to No. 15 in the AP Top 25. Michigan remained behind the Utes, even after a 10-3 upset of then-No. 14 Iowa.

The Pac-12 is down to three Top 25 teams, and the surprising development is that two of them are South members, Utah and ASU (also idle). The North's Washington dropped out after falling 23-13 at Stanford. Oregon is No. 13, following a 17-7 win over California.

No. 1 Alabama and No. 2 Clemson held their spots Sunday after a week off for both, while Ohio State and Georgia are tied at No. 3.

The Crimson Tide received 32 first-place votes and 1503 points and the Tigers had 15 first-place votes and 1,433 points. Georgia got three first-place votes and 1,393 points. Ohio State, which was fourth last week, received 10 first-place votes and 1,393 points.

The last time there was a tie in the top three was Sept. 20, 2015, when TCU and Mississippi shared third.

No. 5 LSU received two first-place votes. Oklahoma stayed No. 6.

Florida moved up three spots to No. 7 after beating Auburn on Saturday. The Tigers slipped five to No. 12.
