The Cougars had only 9 yards rushing on 22 carries.The second interception came on fourth-and-7 from the Kansas 34 late in the third quarter. The Jayhawks took full advantage, as Daniels again went to Grimm, this time for 13 yards, to end a seven-play drive and push the lead to 35-20.BYU closed to within 35-27 with 8:02 left to play on Keelan Marion’s 6-yard run, but Kansas chewed 6:26 off the clock before getting a 23-yard field goal from Seth Keller to ice the victory.
