Iowa knocks out No. 1 seed, defending champion Florida in 2nd round of men's March Madness

Alvaro Folgueiras nailed a 3-pointer with 4.5 seconds remaining and Iowa eliminated defending national champion Florida, sending the top-seeded Gators home with a 73-72 victory on Sunday in the second round of the NCAA Tournament.

Under first-year coach Ben McCollum, Iowa reached the Sweet 16 for the first time since 2015, while Florida (27-8) became the first No. 1 seed to be knocked out of this year's March Madness.

The ninth-seeded Hawkeyes (23-12) wasted a 12-point lead in the second half but rallied in the final minutes.

Xaivian Lee's driving layup put Florida ahead 71-68 with under two minutes left. Bennett Stirtz answered with a floater to cut it to 71-70 with 57 seconds remaining.

After Thomas Haugh missed a 3-pointer, Stirtz missed a running layup and Isaiah Brown grabbed the rebound with 8.9 seconds left. Brown made his second free throw.

But Iowa easily broke Florida's full-court press and Folguerias was wide open in the corner for his 3. Florida didn't get a shot off before the buzzer, with Lee's desperate drive ending with a pass that Haugh couldn't handle.

On the women's side, Syla Swords and Olivia Olson started slow against N.C State. Eventually, Michigan's star sophomores bounced back with fantastic performances.

Olson had all 27 of her points in the second half and Swords bounced back to score 26 and help the second-seeded Wolverines rout the short-handed Wolfpack 92-63 on Sunday and earn a spot in the women's Sweet 16.

"They're hard to contain for 40 minutes," N.C. State coach Wes Moore
