LINCOLN, Neb. -- Ameer Abdullah ran for a career-high 225 yards and two touchdowns and Nebraska's maligned defense was much improved in a 39-19 victory over Illinois on Saturday.
Tommy Armstrong, starting his second straight game in place of injured quarterback Taylor Martinez, led the Cornhuskers (4-1, 1-0 Big Ten) to touchdowns on his first three series and was solid throughout.
Armstrong was 8 of 13 for 135 yards.
Just as big as Armstrong's performance was that of Nebraska's defense, which had been one of the nation's worst through four games.
Illinois (3-2, 0-1), which came in averaging 40 points a game, didn't score its first touchdown until the middle of the third quarter. Twice when the Illini looked as if they would make a game of it, the Huskers made big stops.
Josh Ferguson led the Illini with 114 yards on 19 carries and another 82 yards on eight catches.
Will Grier threw four touchdown passes to four receivers -- all in the first half -- and No. 25 Florida downed third-ranked Mississippi 38-10 on Saturday night.
Leonard Fournette highlighted his SEC-record third straight 200-yard game with a 75-yard touchdown run, and No. 9 LSU overcame Eastern Michigan 44-22 on Saturday night.
An officiating error led to an Oklahoma State touchdown Saturday in the Cowboys' 36-34 win over Kansas State.
Texas A&M receiver Ricky Seals-Jones, who was ejected for targeting midway in the second quarter of Saturday's game, took to Twitter late in the game, retweeting a tweet that questioned the call.
Florida State running back Dalvin Cook exited in the first quarter of the Seminoles' 24-16 win over Wake Forest with a left hamstring injury. He is day-to-day.
As if things weren't going bad enough at Texas, the Longhorns appear to have players on Twitter during lopsided losses and jabs at their coach accidentally being sent from other nearby teams.
