MANHATTAN, Kansas (Ticker) -- Kansas State is making up for years of frustration against Nebraska.
With Ell Roberson rushing for 228 yards and three touchdowns on 30 carries, the 11th-ranked Wildcats handed Nebraska its worst loss in 34 years, 49-13, in a Big 12 Conference contest.
Roberson set a single-game Kansas State rushing record for a quarterback, breaking Michael Bishop's previous mark of 198 against Missouri in 1996.
The highlight of Roberson's day was a 91-yard touchdown scamper late in the first quarter, the longest run by a Kansas State since George Hackney's school-record 86-yard TD in 1948.
The Wildcats (9-2, 5-2) were eliminated from the Big 12 North race when Colorado defeated Iowa State on Saturday night.
"Everyone grew up watching Nebraska, East Coast to West Coast," Kansas State offensive lineman Billy Miller said. "It is so sweet to beat them, they are such an experienced team. Just last year they went to the big show."
The special teams also got into the act as defensive back Marcus Patton blocked a punt that Jerad Johnson recovered in the end zone for a touchdown that made it 21-3 with with five minutes left in the first half.
From 1969-1997, Nebraska won 29 straight against Kansas State, but the balance of power has shifted in recent years. The Wildcats have won three of the last five meetings and Saturday was their most lopsided win ever against the Cornhuskers, who suffered their worst loss since a 47-0 setback to Oklahoma in 1968.
"We played a very good football team," Nebraska coach Frank Solich said. "In order to get it done against them, we knew we had to play well in all three areas. That was our intent and we really did not play well in any of the three areas."
While Kansas State reached nine wins for the ninth time in 10 years, Nebraska's pride suffered another blow.
One of the most impressive streaks in NCAA history is in jeopardy as the Cornhuskers (7-5, 3-4) may need to beat Colorado the day after Thanksgiving to be assured of avoiding their first non-winning season since 1961, the last time they lost as many as five games.
Nebraska's string of 33 consecutive nine-win seasons also is being threatened. The last time the Cornhuskers failed to win at least nine games was 1968, when they went 6-4.
The Nebraska players are at a loss to explain the collapse this season.
"If you would have told me we were going to be like this at the beginning of the season, I would have asked if you had run into a wall or were on drugs because this is not supposed to happen," kicker Josh Brown said.
Kansas, the nation's No. 2 scoring team behind Boise State, wore down Nebraska by rushing for 415 yards on 57 carries.
"I think we've progressed, obviously, since the beginning of the season," Kansas State coach Bill Snyder said. "I think it has been pretty steady and certainly we're playing as well as we have at any point of the season."
Snyder will get no argument from the Cornhuskers.
"They're ranked high in the nation and they showed it today," Nebraska quarterback Jammal Lord said. "We lost it quick. They made the plays when they needed to."
Darren Sproles ran for 159 yards and three touchdowns - all in the second half - and set a Kansas State record with his seventh straight 100-yard game.
"We really like to block four our running backs," Miller said. "We block real well for them because they deserve everything they get. We play hard and they play hard. It goes together real well."
The Wildcats scored 21 unanswered points in the fourth quarter to hand the Cornhuskers suffering their worst loss since a 47-0 drubbing to Oklahoma in 1968.
"It was pretty obvious by the end of the game and they score that they just out-wanted it," Nebraska center John Garrison said. "It's not Nebraska football, we're a better team that that."
Nebraska, which won just one of five road games this season, was held to just 97 yards on the ground, while Lord completed only 9-of-25 passes for 134 yards.
Down 21-6 at the half, Nebraska's defense tried to turn around the game early in the third quarter, forcing fumbles on Kansas State's first two possessions of the second half.
The Cornhuskers converted the first turnover into a 35-yard touchdown run by Lord but could not take advantage of the second as Brown's 29-yard field goal attempt caromed off the right upright.
The Wildcats responded with a seven-play, 80-yard drive, taking a 28-13 lead on Sproles' eight-yard TD run. Nebraska aided Kansas State with 25 yards in penalties during the possession.
Nebraska had one more chance to get back in the game, but the Cornhuskers were turned away when Lord was stopped for a three-yard loss by linebacker Terry Price on 4th-and-1 from the Kansas State 11 with three minutes left in the third period.
The Wildcats put the contest away on Roberson's 25-yard TD run early in the fourth quarter, then continued to pour it on as Sproles added TD runs of 12 and 70 yards to complete the rout.
