LINCOLN, Neb. — Nebraska committed eight turnovers, including four inside the Iowa State 5, and the Cyclones upset the Cornhuskers 9-7 for their first victory in Lincoln since 1977.

Iowa State also ended a 15-game Big 12 losing streak in games played away from Ames, Iowa.

Zac Lee was intercepted by Michael O'Connell and Jesse Smith in the final 3 minutes, ending Nebraska's comeback hopes.

Iowa State (5-3, 2-2), an 18½-point underdog, scored on Grant Mahoney's 52-yard field goal and Jerome Tiller's 47-yard touchdown pass to Jake Williams. Tiller was filling in for regular starter Austen Arnaud, who was out with an injury to his throwing hand.

Tiller ran 19 times for 65 yards and completed nine of 19 passes for 102 yards.

Nebraska (4-3, 1-2) lost its second straight at home. Texas Tech beat the Huskers 31-10 last week.
