COLUMBUS, Ohio — Fairleigh Dickinson, a No. 16 seed in the N.C.A.A. tournament, defeated top-seeded Purdue on Friday, 63-58, in the most shocking upset in men’s college basketball in half a decade.
The win was just the second time a No. 16 seed had defeated a No. 1, after the University of Maryland, Baltimore County beat Virginia five years ago in a 20-point rout.
F.D.U., located in Teaneck, N.J., just across the Hudson River from Upper Manhattan, had never advanced to the second round of the tournament before Friday. It had to defeat Texas Southern on Wednesday in a play-in game just for the right to play Purdue, the Big Ten champion led by the 7-foot-4 center Zach Edey.
