Auburn and Florida both earned hard-fought victories in the SEC.
CORVALLIS, Ore. -- Turns out No. 3 Southern California was vulnerable.
Oregon State capitalized on four turnovers to upset the Trojans 33-31 on Saturday, snapping USC's 27-game Pac-10 winning streak and breaking the national championship race wide open.
USC (6-1, 4-1) had also won 18 straight road games. However, the mighty Trojans had shown cracks in their last three games, each a victory by seven points or fewer.
John David Booty's 2-yard scoring pass to Steve Smith with 7 seconds left pulled USC to 33-31, but Oregon State's Jeff Van Orsow batted down a pass on the 2-point conversion to preserve the lead.
Oregon State fans celebrated wildly in the second half when Matt Moore hit Joe Newton with a 9-yard scoring pass and Sammie Stroughter ran a punt back 70 yards for a touchdown to give the Beavers (4-4, 3-2) a 30-10 lead.
No. 7 Auburn 23, Mississippi 17
OXFORD, Miss. -- Brandon Cox passed for a season-high 253 yards and a touchdown and John Vaughn kicked three second-half field goals for Auburn.
The Tigers (8-1, 5-1 Southeastern Conference) trailed Mississippi (2-7, 1-5) twice, but Auburn converted two third-quarter interceptions thrown by Brent Schaeffer into 10 points.
No. 9 Florida 21, Georgia 14
JACKSONVILLE, Fla. -- Florida's defense forced two fumbles and intercepted two passes, helping ninth-ranked Florida continue its recent dominance over Georgia.
Florida has won eight of nine and 15 of the last 17 in the series, and with the latest victory, it remained atop the Southeastern Conference East Division and moved a step closer to returning to the conference title game for the first time since 2000. The Gators (7-1, 5-1) need to beat Vanderbilt and South Carolina to make it happen.
No. 19 Oklahoma 26,No. 23 Missouri 10
COLUMBIA, Mo. -- Paul Thompson threw two touchdown passes and ran for another score as Oklahoma turned five Missouri mistakes into points.
Two interceptions, a fumble, a blocked punt and a roughing the kicker penalty set up every score for the Sooners (6-2, 3-1 Big 12), who beat No. 23 Missouri for the 15th time in 16 tries.
Oklahoma St. 41,No. 20 Nebraska 29
STILLWATER, Okla. -- Dantrell Savage ran for 117 yards and two touchdowns, and Nathan Peterson returned a fumble for another score to lead Oklahoma State to the win.
Savage scored his second touchdown of the game on a 20-yard run on the second play of the fourth quarter, capping the Cowboys' comeback from an early 16-point deficit. It's the just fourth win for Oklahoma State (5-3, 2-2 Big 12) in 41 games against Nebraska but the second straight for the Cowboys in Stillwater.
No. 21 Georgia Tech 30, Miami 23
ATLANTA -- Georgia Tech got Calvin Johnson back in the offense and took a major step toward reaching the Atlantic Coast Conference championship game.
One week after failing to catch a pass for the first time in his career, Johnson hauled in a tie-breaking, 1-yard touchdown with 6:18 remaining.
Tashard Choice rushed for 107 yards, including a 24-yard touchdown with 31/2 minutes left in a wild fourth quarter. Georgia Tech (6-2, 4-1) scored 17 straight points.
No. 24 Wake Forest 24,North Carolina 17
CHAPEL HILL, N.C. -- Riley Skinner threw a 39-yard touchdown pass to Ken Moore and Jon Abbate intercepted a pass in the end zone to seal Wake Forest's victory. Abbate picked off Joe Dailey on the game's final play after the Tar Heels drove to the Wake Forest 3 with 41 seconds left. The Demon Deacons (7-1, 3-1 Atlantic Coast Conference) have won seven of eight to start the season for the first time since 1979 and third time in school history.
