Oklahoma (3-1) at Dallas
The Longhorns and Sooners go on a carnival elimination ride at their annual State Fair of Texas showdown at the Cotton Bowl. Texas lost at home last week to West Virginia; Oklahoma dropped an earlier home game to Kansas State. This is the 14th time coaches Mack Brown and Bob Stoops have squared off in the series and the first time since 2007 both teams enter with a conference loss. Texas has lost eight straight games against ranked teams since defeating No. 5 Nebraska in 2010.
Kansas State (5-0)
at Iowa State (4-1)
This is an official watch-out Wildcats warning: Iowa State has a history of ruining perfect seasons. Last year, the Cyclones knocked Oklahoma State out of the national title game with a stunning win in Ames. Iowa State is coming off an upset win at Texas Christian.
11 a.m.: Louisville at Pittsburgh, ESPNU.
Noon: Iowa at Michigan State, ESPN; Northwestern at Minnesota, ESPN2; Wisconsin at Purdue, BTN; Brown at Princeton, NBCSN.
Alabama (5-0) at Missouri (3-3)
3:30 p.m., CBS-3
At last check, there was no law against being the nation's top team and catching a few breaks. Alabama's potentially tricky trip in to Columbia got easier because Missouri quarterback James Franklin will miss the game with a knee injury. Alabama already has faced Michigan without star running back Fitz Toussaint (suspended) and Arkansas without quarterback Tyler Wilson (head injury). Missouri is seeking its first Southeastern Conference win and is 0-12 all-time against top-ranked opponents, including a 1978 defeat to Alabama.
Stanford (4-1) at Notre Dame (5-0)
3:30 p.m., NBC-54
Memo to headline writers: It will not be a "shock" if Stanford wins this important game in South Bend. Chroniclers made that mistake earlier this year when Stanford "stunned" USC with its fourth straight win over the Trojans. Stanford similarly has won three straight against Notre Dame, so why would the Cardinal winning another fourth be a big deal?
Florida (5-0) at Vanderbilt (2-3)
6 p.m., ESPNU
This has all the makings for a Florida letdown as the Gators go on the road a week after upsetting Louisiana State in Gainesville. History suggests a Florida victory over Vanderbilt, as the Gators have won 21 straight in the SEC series. But South Carolina could vouch for how tough Vanderbilt is in Nashville after the Gamecocks squeaked out a 17-13 win earlier this season.
7 p.m.: Kentucky at Arkansas, FOXSN.
South Carolina (6-0) at Louisiana State (5-1)
8 p.m., ESPN
Now we find out: Is South Carolina, coming off a dominating 35-7 home win over Georgia, a legitimate national title contender? A two-week SEC road swing through LSU and Florida should answer that question. Now we find out: Does LSU have anything more than a strong defense? The Tigers must win this game to make sure Alabama's Nov. 3 arrival in Baton Rouge has national implications for both schools.
Texas A&M (4-1) vs. Louisiana Tech (5-0) at Shreveport, La.
9 p.m., ESPNU
Hurricane Isaac forced the postponement of this game from Labor Day weekend, but now it's a good-looking matchup with national implications. Texas A&M's only loss came at home to Florida; undefeated Louisiana Tech has wins over Illinois and Virginia. A win for Louisiana Tech would give the Bulldogs an outside, but not impossible, chance to earn an automatic Bowl Championship Series bid.
8 p.m.: Ohio State at Indiana, BTN; Southern Mississippi at Central Florida, CBSSN.
9 p.m.: Tennessee at Mississippi State, ESPN2.
