So much for the top-15 matchup at Autzen Stadium.

Idle Oregon remained at No. 13 in the Associated Press poll released on Sunday.

The Ducks (3-1, 1-0), who had an open date after defeating Stanford 21-6 in the Pac-12 opener on Sept. 21, host California on Saturday at Autzen (5 p.m., Fox).

The Bears (4-1, 1-1) were ranked No. 15 last week before Friday’s 24-17 loss to Arizona State dropped them out of the rankings.

Cal also lost starting quarterback Chase Garbers to a right (throwing) shoulder injury against the Sun Devils. Coach Justin Wilcox said he would know more about Garbers’ status on Monday.

The other Pac-12 teams in this week’s AP poll are No. 15 Washington (up from No. 17), No. 17 Utah (up from No. 19) and No. 20 Arizona State (reentered poll).

Auburn, which defeated Oregon 27-21 on opening night in Arlington, Texas, remains No. 7 after blowing out Mississippi State.

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

Alabama is No. 1 in the APl poll for the first time this season, replacing preseason No. 1 Clemson after the Tigers had a close call against North Carolina on Saturday.

Alabama received 29 of 61 first-place votes as Clemson slipped to No. 2 with 18 first-place votes.

The last time a No. 1 team won and dropped was Ohio State on Nov. 7, 2015, after the Buckeyes beat Minnesota 28-14 at home.

No. 3 Georgia received four first-place votes. Ohio State moved up to No. 4 and received seven first-place votes. LSU was No. 5 and Oklahoma sixth. No. 7 Auburn received three first-place votes.

At the other end of the rankings, No. 24 SMU is ranked for the first time since the program received the so-called death penalty for NCAA rules violations in 1987 and did not compete for two seasons.
