Florida State and Alabama remained in the top two spots in the Associated Press Top 25 poll released Tuesday afternoon.

Defending national champion Florida State beat Oklahoma State in the Cowboys Classic at AT&T Stadium despite some uneasy moments in the second half. Alabama also won in a neutral site game, downing West Virginia 33-23 at Atlanta.

The Seminoles received 46 first-place votes, with Alabama (1), No. 3 Oregon (5) and fourth-ranked Oklahoma (2) also getting votes for the top spot. Surprisingly, LSU, which is 12th, received a first-place vote. The Tigers survived in Houston to beat Wisconsin but trailed most of the game.

Texas A&M was the biggest climber in the latest poll. The Aggies were 21st in the preseason poll but land at ninth this week. Texas A&M's 52-28 win over South Carolina last Thursday pushed South Carolina to the Aggies' old spot in the poll (21). Louisville broke into the poll at No. 25 after the Cardinals' ACC victory over Miami (Fla.) on Monday night.

---Southern Cal redshirt junior quarterback Cody Kessler had toe surgery on Tuesday to help treat a staph infection, but he said the procedue was minor and that he plans to return to practice and play Saturday against Stanford in a key Pac-12 matchup.

Kessler missed Tuesday's practice but expected to be back on the field Wednesday. Coach Steve Sarkisian said Kessler was unable to have the procedure done until Tuesday.

Despite playing with a painful toe, Kessler passed for a career-high 394 yards, threw four touchdown passes and ran for a score in the Trojans' 52-13 victory over Fresno State in the season opener last Saturday.

---Wisconsin quarterback Joel Stave has been shut down indefinitely due to lingering "issues with his shoulder."

Stave started for the Badgers last season, but Tanner McEvoy was given the nod in Houston last week against LSU.

Stave started every game and completed 61.9 percent of his passes for 2,494 yards with 22 touchdowns and 13 interceptions in 2013.

---Tennessee will be without starting left tackle Jacob Gilliam for the rest of the season after he suffered a knee injury in the Volunteers' 38-7 victory over Utah State on Sunday.

Gilliam is a fifth-year senior and former walk-on who started for the first time in his career. He had just received a scholarship during the summer.

---Minnesota junior defensive tackle Scott Ekpe suffered a knee injury during the opener and might miss the remainder of the season.

Coach Jerry Kill called the unspecified injury to Ekpe's right knee a major blow for the Gophers, who defeated Eastern Illinois in their first game of 2014 last Thursday. The St. Paul Pioneer Press reported that Ekpe tore the anterior cruciate ligament.

Defensive linemen Alex Keith and Yoshoub Timms also left Thursday's game with leg injuries, but Kill did not indicate whether the two would be available for Saturday's home game against Middle Tennessee.

---A day after putting running back Mike Davis in the "sort of doubtful" category for Saturday's game against East Carolina, South Carolina Gamecocks coach Steve Spurrier said Tuesday that he now expects Davis to be available.

Davis was limited to four carries because of a rib injury in the Gamecocks' season-opening loss to Texas A&M.

---Texas starting quarterback David Ash, the player Texas was depending on to manage the offense with an experienced hand, will not play this week as he suffered concussion-like symptoms following Texas' 38-7 victory over North Texas.

Ash, who missed most of last season with a concussion, might be on the shelf long term and there's speculation he could even call it a career. He was injured on the first hit he took in the win over UNT.

For the moment, Texas hands the offense to sophomore Tyrone Swoopes, who will start against BYU on Saturday. Swoopes became the backup quarterback last season when Case McCoy took over the offense after Ash was initially sidelined with a concussion. Swoopes played in six games but only attempted 13 passes. He completed five for 26 yards. He also rushed 20 times for 79 yards, all in mop-up duty.

---Losing quarterback Bryce Petty would be a backbreaker for the Bears, but the record-setting passer said he plans to play with two cracked bones in his back.

Petty was diagnosed with fractures in the transverses processes -- tiny bones in the back -- but listed as day to day and might play in Saturday's game against Northwestern State.

Petty, considered a preseason contender to win the Heisman Trophy, left at halftime of Baylor's 45-0 victory over SMU on Saturday. He completed 13 of 23 passes for 161 yards.
