While there had yet to be a true bracket-busting upset in this year's NCAA Tournament as of Sunday evening, only one registered bracket remained perfect amid tens of millions of entries, according to the NCAA.

Meanwhile, CBS, ESPN, and Yahoo all announced Sunday that they had no perfect bracket predictions remaining.

That's somewhat surprising considering that all top-3 seeds in each region advanced through the Round of 64. The highest seeds to lose on the first weekend were Kansas and Kansas State, both 4-seeds.
