UCF almost pulled off the biggest victory in the history of its men's basketball program.
Zion Williamson had 32 points and Canadian RJ Barrett scored on a putback to put top seed Duke ahead in a 77-76 triumph over the Knights in the second round of the NCAA men's basketball tournament.
The Blue Devils trailed 76-73 until Williamson hit a layup over Tacko Fall with 14.4 seconds left.
Williamson was fouled on the play and missed the free throw, but Barrett scored to cap his 16-point performance and put Duke ahead.
Ninth-seeded UCF had a final chance, but B.J. Taylor missed a short jumper and Aubrey Dawkins failed on his tip attempt with less than 2 seconds left.
Duke will play Virginia Tech in the regional semifinals.
