After Langford missed a jumper with 37 seconds left, Texas Tech's Jarrius Jackson rushed a 3-pointer, but Kansas' Aaron Miles traveled trying to keep the rebound away from three Red Raiders.

Langford, who tied the game at 69-69 on a driving layup with 4.1 seconds left in regulation, scored 24 points on 10-of-22 shooting.
In the first overtime, Dora's free throw with 15 seconds left gave the Red Raiders a 74-72 lead. But Christian Moody tied the game on a follow of Wayne Simien's missed layup with a two seconds remaining. Zeno missed a desperation shot at the buzzer.
