In Sunday afternoon’s third heart-pounding NCAA tournament game, Iowa State’s DeAndre Kane made a layup with two seconds left to give the third-seeded Cyclones an 85-83 victory over sixth-seeded North Carolina in San Antonio.

The Cyclones and Tar Heels battled through nine ties and 11 lead changes, both looking ready to run away with the game at points, both pulled back toward scoreboard equilibrium again and again.

Confusion reigned in the 1.6 seconds following Kane’s go-ahead score, as the clock failed to start when North Carolina attempted to inbound the ball, meaning the horn — which would have sounded as the Tar Heels carried the ball over half court — had yet to buzz when North Carolina reached the half-court line. The Tar Heels tried to call timeout, hoping to create a play that would yield a shot in the scant remaining time, but officials reviewed the replay to assess the clock glitch, and ultimately declared the game over.

Kane did it all for the Cyclones, scoring 24 points to lead his team while dishing seven assists and grabbing 10 rebounds. His play helped Iowa State through its first game without third-leading scorer Georges Niang, who was injured in the Cyclones’ round-of-64 win over North Carolina Central. The Cyclones are making their first Sweet 16 appearance since 2000.
