Upset alert!
We're onto the Round of 32 in the Ultimate Fan Bracket, and the Round of 64 was a fun one – filled with quite a few surprises.
Let's see where everyone stands:
One of our No. 1 seeds, Duke, went down in the first round!
The Blue Devils fell at the hands of 16-seed, the Lehigh Mountain Hawks.
It wouldn't be the first time the Blue Devils fell at the hands of Lehigh.
Poor, Duke.
But that wasn't the only upset that blew our minds.
The UMBC Retrievers, a 12-seed, had an Iron Man moment over the 5-seed Virginia Cavaliers.
And they loved every second of it.
You know what they say about the NCAA tournament...
However, the Retrievers seem to be a little worried about their next matchup, the 4th-seeded Maryland Terrapins.
Can they channel their inner Super Hero again?
And despite their major upset over 4-seed Arizona, Murray State – a 13-seed – played it relatively cool.
Now that we've got upsets on your mind, head over to our CBBonFOX Twitter to vote for which upset you think stole the show in the Round of 64:
Back to the fans.
The 11th-seeded Dayton Flyers lived up to their name, flying right over 6-seed, the Iowa Hawkeyes.
All it took was a few words of encouragement from Flyers superstar forward Obi Toppin.
And now, Dayton is ready for the Round of 32:
But they're up against some stiff competition in 3-seed, the Wisconsin Badgers, which defeated 14-seed Montana in the Round of 64.
The Wisconsin Badgers were right on Dayton's heels in highest number of votes, and it looks like they won't be going down without a fight.
Still in the Big 10, No. 3 seed Michigan is feeling confident after its first round win over 14-seed UNC Wilmington.
Plus, their competitor, the 6th-seeded Wofford Terriers, are hyped for battle.
The Fighting Illini of Illinois, a 6-seed, had a close call in the first round, but survived 11-seed Loyola Chicago.
Now, they're fired up for their next matchup against 3-seed West Virginia.
Michigan State's mascot Sparty is bringing his warrior mentality to the bracket, and after helping the 2nd-seeded Spartans move past 15-seed Hawaii, Sparty is ready for a Round of 32 matchup with 10-seed BYU.
