The upsets have begun and the little guys are moving into The Associated Press poll.

After ranked teams started the season 21-0, five fell to unranked opponents this weekend, shaking up the media poll released Sunday.

While No. 1 Southern California and No. 2 Oklahoma had no problems holding on to the top two spots with lopsided wins, four teams fell out of the rankings - Kansas State and Missouri from the Big 12 and Clemson from the Atlantic Coast Conference and Oregon from the Pac-10.

They were replaced by No. 19 Fresno State, which won at Kansas State, No. 23 Boise State from the Western Athletic Conference, and No. 24 Louisville and No. 25 Memphis from Conference USA.

The Tigers are ranked for the first time.

"Mid-majors are starting to come up, and good things are happening," Fresno State defensive end Garrett McIntyre said. "We want BCS bids and we think we can get them, but we have to go undefeated in order to do it. I think it's our time."

For Fresno State, it's looking like a repeat of the 2001 season. That year David Carr and the Bulldogs knocked off three teams from marquee conferences and made a run at breaking into the Bowl Championship Series.

"This team still has a long way to go," Fresno State coach Pat Hill said. "Both teams are different, but they play with the same hunger and aggression. We've just got to keep playing like this."

Saturday's Fresno State win in Manhattan followed a victory at Washington six days earlier.

Boise State extended the nation's longest winning streak to 13 games by beating Oregon State 53-34 on Friday. The Broncos finished last season ranked 16th after going 13-1.

"As every coach will tell you, it's where you end up," Boise State coach Dan Hawkins said Sunday. "But it's not like you don't put any credence in it."

With Kansas State and Missouri, which lost at Troy on Thursday, falling out of the rankings, it leaves Oklahoma and No. 6 Texas as the only Big 12 teams in the poll. It's the first time the Big 12 has had fewer than three teams ranked since the league started in 1996.

Clemson lost in the closing seconds to Georgia Tech and Oregon was upset at home by Indiana.

Back at the top of the poll, USC picked up one first-place vote (52). Oklahoma still has 10 and No. 3 Georgia, which needed to rally from 16 down win at South Carolina, lost a first-place vote and now has three.

Miami is No. 4 after an overtime victory over Florida State, which fell four spots to No. 8.

LSU is fifth, Texas is sixth and West Virginia is seventh.

Ohio State and California fill out the top 10.

While the Buckeyes escaped the upset against Marshall with a last-second field goal, their rivals to the North weren't so lucky. Michigan's loss at Notre Dame dropped the Wolverines nine spots to No. 17.

"You can't give up big plays, you can't have a punt blocked and do the things we did - turn the football over late in the game - and expect to win," Michigan coach Lloyd Carr said.

Purdue's second straight 50-point performance helped the Boilermakers make the biggest jump among ranked teams, seven spots from No. 25 to No. 18.

Completing the second 10 are No. 11 Florida, No. 12 Virginia, No. 13 Tennessee, No. 14 Auburn, No. 15 Utah, No. 16 Iowa and No. 20 Wisconsin.
