Alabama is a unanimous No. 1 and LSU slipped another spot in The Associated Press college football poll.
The Crimson Tide received all 60 first-place votes for the first time this season. The Tigers had a second straight sketchy performance, this time against Towson, and dropped a spot for the second consecutive week.
LSU won 38-22 at home Saturday and is ranked No. 4 in the new media poll.
Oregon remained No. 2, and Florida State moved past LSU to No. 3. After beating Stanford on Thursday, Washington moved into the rankings at No. 23.
Stanford followed up its big win against Southern California by losing in Seattle, dropping the Cardinal 10 spots in the poll to No. 18.
The Pac-12 has six teams in the Top 25, including No. 14 Oregon State. The last time the Pac-12 was so well represented in the AP poll was Sept. 15, 2002.
Oklahoma State: After taking another look at the replays, coach Mike Gundy still has questions about Texas running back Joe Bergeron's winning touchdown in the teams' Big 12 opener Saturday.
"I think he fumbled," Gundy said. "I don't know what else to say."
Officials ruled on the field that Bergeron had scored on a 2-yard touchdown run with 29 seconds left. Oklahoma State's Daytawion Lowe came out of a pileup at the goal line with the ball, but the initial ruling was upheld after an instant replay review.
The Longhorns (4-0) won 41-36 and moved
Gundy said he didn't get an explanation of the ruling on the play.
UCLA: Wide receiver Devin Lucien broke his clavicle during Saturday's 42-14 victory at Colorado and will miss eight to 10 weeks, coach Jim Mora said Sunday.
Lucien, a redshirt freshman, will have surgery this week to repair the injury. He has 10 receptions for 188 yards and is second on the team in yards per catch with 18.8.
Lucien's absence opened some playing opportunity for other rising players. Freshman Jordan Payton got his most significant action of the season against Colorado, and walk-ons Jerry Rice Jr. (Menlo-Atherton) and Logan Sweet also got on the field. Rice had three catches for 30 yards.
Auburn: Wide receiver Quan Bray has been suspended after his arrest during a traffic stop in Georgia, Tigers coach Gene Chizik said. Bray won't play Saturday against Arkansas, and Chizik hasn't determined how long the suspension will last.
Bray faces charges of loud music and possession of alcohol under 21, as well as a driver's permit violation. Police said he hadn't been drinking. Chizik praised Bray for his character and strength after Bray's father, Jeffery Jones, was accused of shooting and killing the player's mother, Tonya Bray, in July 2011.
