Well, it's called March Madness for a reason.
Two perennial powerhouse basketball teams, No. 3 seed Syracuse University and No. 2 seed Villanova University, were knocked out during the second round of the NCAA tournament on Saturday night.
And this probably means that your bracket is busted.
No.11 seed Dayton stunned the Orange by a final score of 55-53 and in case you missed it, the game was a nail-biter to the very end. Syracuse freshman Tyler Ennis tried to shoot the potential game-winning three pointer with two seconds left on the clock but the basketball hit the back rim.
The Flyers became the first Cinderella team of this year's tournament. They are also going to the Sweet 16 for the first time in 30 years.
They will face off against either No. 2 seed Kansas or No. 10 seed Stanford.
In another upset, that wasn't nearly as close as the Dayton Syracuse game, No. 7 seed UConn beat Villanova by a final score of 77-65. The Wildcats became the highest seed knocked out of the tournament, so far.
The Huskies will face off against either No.3 seed Iowa State or No. 6 seed North Carolina.
Welcome to the Big Dance, Dayton and UConn.
