COLUMBIA, S.C. — Zion Williamson took on 7-foot-6 Tacko Fall at the end and won. So did top-seeded Duke — barely — when two last-ditch shots by UCF rolled off the rim.

Williamson had 32 points and helped rally the Blue Devils from behind in the final minute for a 77-76 victory Sunday to reach the Sweet 16.

Aubrey Dawkins finished with 32 points for the Knights, but his tip-in try just missed in the final seconds.

Duke coach Mike ­Krzyzewski “talks a lot about the basketball gods,” a happy Williamson said. “They had our backs today.”

Williamson was key to the comeback. He made a layup over Fall with 14.4 seconds left to draw Duke within a point as Fall fouled out on the play. Williamson missed the free throw, but R.J. Barrett scored on a putback to put the Blue Devils (31-5) ahead.

Barrett said he had watched plenty of NCAA Tournament games where players missed foul shots and an offensive rebound could have made the difference.

“I was going to do whatever I can to get this rebound,” he said.

Ninth-seeded UCF (24-9) had a final chance. Two of them, actually, from in close.

B.J. Taylor missed a short jumper, and Dawkins failed on his tip attempt with less than two seconds left, the ball spinning off the rim. Duke got the rebound, ran out the clock and moved on to the Sweet 16 for 27th time and fourth time in the past five years.

“It was up there forever, I felt like, in slow motion,” Dawkins said.

Dawkins cringed at the miss. His father, Johnny, is the UCF coach and was a former Duke star and longtime assistant under Krzyzewski. The two coaches shared a long embrace at midcourt after it was over.

“It’s tough,” the elder Dawkins said. “I love that man. Without him, I wouldn’t be where I am today.”

Barrett finished with 16 points.

Williamson, the game’s most explosive player, was clearly affected by Fall. Who would not be as the Knights senior stood 11 inches taller than Williamson and has a wingspan of 8 feet 4?

With Fall inside, Williamson went to the perimeter, hitting three 3-pointers after entering with just 18 on the season. When Fall was hit with foul trouble, Williamson charged to the hoop.

Fall finished with 15 points and six rebounds in his final college game.
