Manhattan ? After his record-setting performance as a ballcarrier, Kansas State quarterback Ell Roberson stayed in the game to help a teammate break two more school marks.

Roberson ran for 228 yards – the most ever by a Kansas State quarterback – and three touchdowns as the 11th-ranked Wildcats handed Nebraska another humiliating loss Saturday, 49-13.

With just more than two minutes left, Roberson rolled right on the option, then pitched to sophomore tailback Darren Sproles. The resulting 70-yard touchdown run – Sproles’ third of the game – finished off K-State’s most lopsided victory ever against the Cornhuskers.

It also gave Sproles 155 yards, his seventh straight 100-yard game and eighth of the season. Josh Scobey set the school record last season with seven 100-yard games, and Isaac Jackson had six straight in 1973.

“I really wanted the guy to bite on me, so I could get the ball to (Sproles) and he could go around on the outside,” Roberson said. “He did, and I pitched it, and Sproles just took over.”

Roberson’s 91-yard first-quarter touchdown run was the second-longest run against Nebraska, topped only by Gale Sayers’ 99-yarder for Kansas University in 1963. It was also the longest Kansas State run since Gerald Hackney’s 96-yarder against the Jayhawks in 1948.

“It looked like the Red Sea,” Roberson said. “I spotted the goal line and I just ran away.”

With one game left, against Colorado, Nebraska (7-5, 3-4 Big 12 Conference) is assured of its first non-winning conference record since its 3-4 Big Eight mark in 1968. The Huskers’ five regular-season losses already are the most since the 1961 team went 3-6-1, and Saturday’s loss dropped their road record against ranked teams to 1-7 under coach Frank Solich.

Nebraska still leads the series 72-13, with two ties, but Kansas State’s previous largest margin was a 27-0 shutout in 1953.

The Wildcats (9-2, 5-2) had their largest margin against a longtime opponent for the third straight week. They beat Kansas 64-0 and Iowa State 58-7.

The Wildcats’ defense shut down a Nebraska running game that had gone over the 300-yard mark in five of the Huskers’ previous six games.

Nebraska managed just 97 yards on the ground, 38 in the first half. Quarterback Jammal Lord was sacked six times and held to 21 yards on 47 carries.

“Anything is better than 97 yards rushing,” Cornhuskers center John Garrison said. “That’s just sick.”
