Florida had a chance to pull out a win, but was unable to even get a shot off, withXaivian Leedriving to the basket and trying to dump it off to Haugh, only for an Iowa defender to stick his hand in to block the pass as time expired.
With the win, Iowa earned a trip to its first Sweet 16 since 1999, a milestone it reached in just its first season under coach Ben McCollum. It became the ninth No. 9 seed to defeat a No. 1 seed since 1979.
The Gators became the first No. 1 seed to lose in the tournament this season. Since Villanova in 2017, only one reigning national champion — UConn in 2024 — has advanced past the second round of the tournament.
Folgueiras' triple was one of two game-winning shots Sunday, with St. John's guard Dylan Darling giving his team a 67-65 victory over Kansas earlier in the day on a layup as time expired.
