Oklahoma fell to Texas Tech. Wisconsin took its second loss of the year.
The BCS is not in a state of upheaval yet, but just give it time.
With a handful of weeks to be played before conference championships there is sure to be some drama.
Here are 10 teams with strong opportunities to be BCS spoilers down the stretch.
Texas Tech has done it once already. The Red Raiders went into Norman and handed the Oklahoma Sooners their first loss of the season.
The upset opportunities will keep coming. Their next two games are against the Texas Longhorns and the Oklahoma State Cowboys.
The question is which Texas Tech team will we see. Will it be the one that took down the Sooners, or the team that got crushed by Iowa State a week later?
Regardless of wins and losses, Texas Tech has already proved it is a team capable of upsetting anybody.
The Longhorns and Cowboys need to be ready for the Red Raiders' best shot.
Andrew Luck and his Stanford teammates are still undefeated after surviving a triple-overtime scare against USC.
If the Cardinal are able to get past Oregon, an undefeated season and BCS berth will be within their sights.
The spoiler alert on this schedule comes in Stanford's final regular-season game when it plays the Notre Dame Fighting Irish.
Brian Kelly doesn't have Notre Dame all the way back to its previous glory, but this 2011 team is more than capable of pulling off an upset.
Texas A&M will look to do even more damage to the Big 12 before heading off to join the SEC.
The Aggies still have games at Oklahoma and Kansas State prior to closing out the regular season at home against Texas.
Texas A&M could be the most talented three-loss team in the country.
It comes into this stretch unranked, but keep in mind that this was a top-10 team in the preseason polls. The season hasn't gone according to plan, but the Aggies would love to tarnish the season of their conference rivals.
The Houston Cougars are steamrolling through Conference USA and putting up more than 50 points per game in the process.
Case Keenum's squad needs to finished undefeated and hope for some respect in the polls in order to reach a BCS game.
A singles loss for Houston would truly spoil its season.
Undoubtedly, Houston will be a significant favorite when it travels to Tulsa to close out the regular season against the Golden Hurricanes.
Tulsa is only 5-3, but those losses have come at the hands of Oklahoma, Boise State and Oklahoma State. The toughest game that the Cougars have played in was their opener, in which they beat a mediocre UCLA team.
Playing at home and having experience against top teams this season give Tulsa a very real chance of handing Houston its first and only loss.
Due to the Prior-Tressel fiasco and a 3-3 start, Ohio State fell off the national radar.
Things in Columbus are starting to look up after consecutive wins against Illinois and Wisconsin.
Regardless of the state of the program, Ohio State promises to be a tough game for any Big Ten opponent.
The Buckeyes will finish their season with games against Penn State and Michigan. A talented, prideful underdog playing in a rivalry game is scary for the opposition.
The Buckeyes are still in the thick of a divisional race in the Big Ten and will have plenty of motivation.
Throw out wins and losses when Pitt and West Virginia meet in the Backyard Brawl.
The Panthers are heading off to the ACC and the Mountaineers have recently been accepted into the Big 12. With the future of this rivalry uncertain both teams will be amped up to win this year.
West Virginia is poised to climb into the Top 20 during its final games unless Pitt can get in the way.
Panthers' star running back Ray Graham is on the shelf with an injury, but that wont stop them from trying to take down their most hated rival at least one more time.
Iowa has ample opportunity to shake the Big Ten race during its final games.
The Hawkeyes will host each of the Michigan schools during the next two weeks and close the year out in Nebraska.
The back-loaded schedule means that while the Hawkeyes are out of any BCS consideration, they still have a chance to make some waves in the rankings.
You can expect Iowa to come away with an upset victory in at least one of these games.
The Auburn Tigers were the only ranked team to make the spoiler list.
The game to watch on their schedule is the Iron Bowl to close out the season. The Alabama Crimson Tide will have to travel into enemy territory, possibly with an undefeated season on the line.
Nobody will confuse this Auburn team with last year's, but as has already been said several times, in a rivalry game all bets are off.
Look for Auburn running back Michael Dyer to give the strong Alabama defense all it can handle.
Like Auburn, TCU is another team that has taken a step back after losing a quarterback to the NFL.
The Horned Frogs are 6-2 but have not beaten any particularly strong opponents.
The odds will be long, but TCU has a chance to play spoiler when it heads to Boise State on Nov. 12.
As it transitions to a power conference, TCU would love to knock down Boise State and stop the Broncos' national championship push.
This has not been Florida's year, but Will Muschamp will have the Gators back on top soon enough.
In the meantime, the Gators get a rare opportunity to play spoiler.
On Nov. 12 they will take on a South Carolina Gamecocks team that has struggled to score the past two weeks. It would be little consolation in a disappointing season, but there is always something sweet in taking down a rival, especially one run by "the old ball coach."
