Nebraska, after its second consecutive shutout, retained the No. 1 ranking Sunday while Michigan moved up a notch to No. 4 in the Associated Press' Top 25 poll.
The Cornhuskers (7-0), who beat Kansas, 35-0, received 35 first-place votes and 1,704 points from the panel of 70 sportswriters and broadcasters, slightly increasing their lead over No. 2 Penn State.
The Nittany Lions (6-0), who did not play Saturday, had 25 first-place votes and 1,665 points. Last week, when the Huskers replaced the Lions at No. 1, Nebraska led in first-place votes, 33-26, and points, 1,698-1,668.
Florida State (7-0) defeated Virginia, 47-21, and remained No. 3 with eight first-place votes and 1,629 points.
The Wolverines (7-0) beat Michigan State, 23-7, and moved ahead of idle North Carolina (7-0). Michigan did not receive a first-place vote but totaled 1,514 points, seven more than the Tar Heels, who collected two first-place votes.
Sullivan leaving as TCU coach
FORT WORTH, Texas -- Texas Christian coach Pat Sullivan, whose Horned Frogs have been through disciplinary upheaval and controversy since 1996 and are 0-7 this year, said he's leaving after this season.
The former Auburn quarterback and 1971 Heisman Trophy winner led the Frogs to consecutive winning seasons in 1994 and 1995 and an Independence Bowl bid in 1994. But a series of disciplinary problems decimated his roster last year and the team has been hapless in 1997.
"I think it's appropriate that I step down as head football coach at the end of the season," Sullivan said. "This has been a disappointing year."
Sullivan, 47, has two years left on his contract and is 23-39-1 as TCU's head coach.
Report: Mackovic to be fired
DALLAS -- University of Texas officials have reached a consensus that coach John Mackovic should be fired or reassigned after this season, The Dallas Morning News reported.
In its Monday editions, the newspaper cited two school sources it did not identify as saying officials are in agreement about starting the process to reassign or fire the sixth-year coach. Athletic director DeLoss Dodds, however, said Sunday that there is no movement afoot to get rid of Mackovic.
The Longhorns are 40-25-2 under Mackovic, including last season's Big 12 championship. But they have stumbled badly this season, going 3-4 overall and 1-3 in conference play.
Woman kicker sticking with it
PORTLAND, Ore. -- Liz Heaston is getting such a kick out of football that she's decided not to give it up.
The first woman to play college football had expected to retire after her historic pair of conversion kicks in a one-game appearance a week earlier, but Willamette coach Dan Hawkins told her to get in uniform for the second half of Saturday's game against Southern Oregon.
And after going 0 for 2 on extra points in the Bearcats' 41-27 victory, she says she'll keep practicing with the team and hopes to get in a game again somewhere down the road.
