Boston College, Kentucky and Maryland escaped. Big Ten powers Indiana, Ohio State and Wisconsin did not.
The NCAA Tournament opened Thursday with a series of close calls and stunning losses.
Georgia State, led by former Maryland coach Lefty Driesell, knocked off the sixth-seeded Badgers 50-49 earlier in Boise, Idaho, to set up a second-round showdown with the Terrapins.
"I told my team this might be the greatest win I've ever had," said Driesell, fired by Maryland 15 years ago. "We came back in the second half and showed what kind of club we have."
Georgia State's Darryl Cooper made a four-point play and a steal to set up the game-winning basket in the final minute. The win wasn't sealed until Wisconsin's Mark Vershaw missed two free throws with 3.2 seconds to play.
Kevin Morris led Georgia State (29-4) with 18 points. Mark Vershaw had 19 for Wisconsin (18-11), which played in the Final Four last year.
Maryland, seeded third, beat George Mason 83-80.
The Terrapins (22-10) used Steve Blake's late three-pointer and Juan Dixon's two free throws with 4.9 seconds left to beat George Mason (18-12).
Dixon and Byron Mouton scored 22 points each for Maryland.
"We dug down deep in the second half," said Maryland coach Gary Williams. "It was a struggle, but we won."
