Penn State and LSU wanted to avoid letdowns after emotional victories last week. Neither did.

Ohio State and Florida wanted to bounce back after losses last week. Both did.

No. 1 Penn State (6-0, 3-0 Big Ten) had to score twice in the fourth quarter to beat lowly Minnesota 16-15 Saturday and keep alive hopes for a national championship.

"It was a win. You shouldn't apologize for it," said Coach Joe Paterno one week after the Nittany Lions beat Ohio State.

LSU, coming off an upset of previous No. 1 Florida, wasn't as fortunate, losing 36-21 at home to Mississippi.

"We were emotionally drained," said LSU cornerback Cedric Donaldson. "Guys just weren't into it this week like they were last week."

No. 7 Florida, playing without suspended quarterback Doug Johnson, used a smothering defense to shut down No. 6 Auburn 24-10.

"With our quarterback situation muddled, we didn't want to put the game in our quarterback's hands," said Florida Coach Steve Spurrier.

Penn State came out flat but survived thanks to two touchdowns by Curtis Enis and a late Minnesota turnover. Chris Snyder's fumble recovery set up Enis' game-winning, 10-yard touchdown run with 3:59 to play.

"It was like a gift from God," said linebacker Jim Nelson. "You couldn't think of a more perfect time for those things to happen. Sometimes championship teams get lucky."

No. 2 Nebraska 29, Texas Tech 0

At Lincoln, Neb., Ahman Green ran for 178 yards and a touchdown and the Cornhuskers' defense recorded its first shutout of the season.

Nebraska (6-0) rolled up 400 yards rushing, while holding Texas Tech to 127 total yards.

No.3 Florida St. 38, No. 21 Georgia Tech 0

At Tallahassee, Fla., Thad Busby threw for 399 yards and three touchdowns and Travis Minor raced 27 yards for a score as Florida State overcame a lethargic start.
