TOPEKA, Kan. (THE DRIVE) TCU trailed 80-76 with just over a minute remaining, but a parade of free throws closed the gap, and Alex Robinson's driving layup gave TCU the lead back with 31 seconds left
Frank Mason answered with a pair of free throws for Kansas (28-4), but the Horned Frogs got the ball to Bane in the corner and he was fouled by Svi Mykhailiuk while putting up a shot.
Bane calmly drained all three of them, and Devonte Graham's long 3 at the buzzer bounced off the rim as the Horned Frogs leaped off their benched to celebrate a massive upset of the No. 1 seed.
Even with the lose, the Kansas Jayhawks are the 1-seed in the Midwest Region of the NCAA Tournament and will head to Tulsa, OK for the first round.
Kansas will face the winner of North Carolina Central vs. UC Davis in the first round. If the Jayhawks win, their next opponent will be the winner of 8-seed Miami (FL) vs. 9-seed Michigan State.
The Jayhawks finished the season 28-4 and won a 13th-consecutive Big 12 regular season title.
Andy Spencer, a KU Golfer, finished tied for eighth in the Desert Mountain Intercollegiate Tournament. Spencer shot a three-round total of 3-under 213. The team tied for fourth place.
Barry Brown had 21 points, D.J. Johnson added 13 and Kansas State topped ninth-ranked Baylor 70-64 in the Big 12 Tournament on Thursday night, clinching not only a spot in the semifinals but most likely a spot in the NCAA Tournament.
It was the second time the sixth-seeded Wildcats (20-12) have beaten the Bears (25-7) this season, giving them precisely the kind of marquee victory that the selection committee favors.
In the second round against West Virginia, K-State was not able to hold onto their lead and lost 51-50. A foul against Esa Ahmad allowed free throws to give WVU the lead with 20 seconds left. Stokes put up an off-balanced 3-pointer that missed, and was nearly tipped in by Dean Wade, but the Cats would ultimately lose.
These performances were enough to give K-State an opportunity at the NCAA tournament. K-State is the 11 seed and will play Wake Forrest on Tuesday in the play-in game in Dayton, Ohio. The winner of K-State-Wake Forrest will play Cincinnati on Friday.
