The Sooners (5-4, 3-2 Big 12) failed to score a touchdown for the first time since a 29-0 loss to Texas A&M in 1998.
The Cornhuskers (6-3, 3-2) won despite getting just seven first downs and 180 total yards. They were able to get a yard when they really needed it, after Prince Amukamara returned an interception to the OU 1 in the second quarter. Zac Lee threw a short pass to Ryan Hill for the only touchdown of the game.
Oklahoma's last two possessions ended on interceptions, including O'Hanlon's third.
O'Hanlon ran back his first interception 30 yards to set up Alex Henery's 28-yard field goal.
Roy Helu Jr. ran for 138 yards on 20 carries for Nebraska.
