The Longhorns would score in three plays on their first possession, but a unsportsmanlike conduct penalty would give the Jayhawks a short field to start their possession. A two yard run from Devin Neal made the score 56–55 Texas. Kansas coach Lance Leipold would take the risky play and go for the two point conversion. The risk would prove successful as Jared Casey would catch the pass in the end zone giving KU the win 57–56. The win ended multiple losing streaks for Kansas: 8 straight overall losses, 18 straight within the Big 12, 20 straight to FBS opponents, and 56 straight in road conference games.
