Auburn (5-2) at No. 1 LSU (7-0)
3:30 p.m. (CBS-27): LSU seeks to keep pace with unbeaten and second-ranked Alabama in the SEC West. Auburn has a chance to pull within a game of LSU and also clinch bowl eligibility. Auburn sophomore quarterback Clint Moseley, who'll be making his first start, will face an LSU defense that has been among the best in the nation this season but will be missing suspended star cornerback Tyrann Mathieu and fellow defensive back Tharold Simon. With running back Spencer Ware also suspended, Michael Ford is LSU's top remaining rusher, with 369 yards and six TDs. Auburn defensive end Corey Lemonier leads the SEC with six sacks. The home team has won 10 of the past 11 games in the series, the exception being LSU's 26-21 victory in 2008.
No. 4 Wisconsin (6-0) at No. 15 Michigan St. (5-1)
8 p.m. (ESPN): These are two of three teams with unbeaten Big Ten records (Penn State is the other). They're in different divisions, so this could be a preview of the conference's first title game later this year. The Spartans handed the Badgers their only regular-season loss last season. The Badgers are averaging 5.9 yards a rush and have allowed only eight sacks. Wisconsin's starting offensive line (tight end included) averages 301 pounds. Michigan State's starting defensive line averages 282. Wisconsin quarterback Russell Wilson is completing 74 percent of his passes. He's thrown for 14 touchdowns and one interception. The Spartans ran for 175 yards on 45 carries in last year's win over Wisconsin. The home team has won the last six games in the series.
Never miss a local story.
North Carolina (5-2) at No. 8 Clemson (7-0)
Noon (ESPN): Clemson is off to its best start since 2000. North Carolina's Giovani Bernard leads all freshman in the country with nearly 110 yards rushing a game, and he leads the ACC with nine rushing TDs. Clemson receiver Sammy Watkins broke C.J. Spiller's single-game all-purpose yardage school record and had three TDs, including an 89-yard kickoff return, in last week's 56-45 win over Maryland.
Player to watch
Kellen Moore, QB, Boise State: Moore may not have to throw many passes against Air Force on Saturday, but given the Falcons' porous pass defense Moore could get a lot for less. He remains one of the nation's most accurate throwers (75.9 percent) and he has 21 TD passes with four interceptions for the fifth-ranked and unbeaten Broncos. A victory Saturday for Moore would be the 45th of his career, tying him with ex-Texas Longhorn Colt McCoy for most career wins by a QB.
