Oklahoma vs North Dakota State: Live Score, Highlights for Round of 64

The North Dakota State Bison became the latest No. 12 seed to upset a No. 5 seed in the NCAA tournament, knocking off the Oklahoma Sooners 80-75 in overtime on Thursday night in Spokane.

With the win, the Bison advance to Saturday’s third round, and they’ll await the winner of No. 4 seed San Diego State and No. 13 seed New Mexico State for a chance at the Sweet 16.

North Dakota State (26-6) led for most of the way, but they blew their lead late in the second half and trailed the Sooners by three with just over 18 second to play in regulation.

Oklahoma (23-10) had just missed a chance to ice the game away when Isaiah Cousins couldn’t connect on his second free throw—which would’ve made it a two-possession game—and the Bison snagged the rebound.

And then we saw one of those moments, and one of those plays, that define March Madness.

Lawrence Alexander—who finished with a career-high 28 points—nailed a clutch three with just 11 seconds left to tie the game.

Oklahoma had several chances to win the game on the other end, but failed to convert, and the game headed to overtime.

The extra frame belonged to the Bison, who outscored the Sooners 14-9 and overcame a tremendous individual effort from Oklahoma senior guard Cameron Clark.

Clark, who finished with 25 points, scored 22 in the second half and overtime, but it just wasn’t enough to extend his career in Norman.

With results like these, it’s only going to be so long before it’s considered an upset when the No. 5 seed defeats the No. 12 seed.

North Dakota State joins Harvard—who defeated Cincinnati earlier on Thursday—as the second No. 12 seed to advance to the third round in this year’s tournament.
