Zion Williamson suffered a mild knee sprain after blowing out his shoe 36 seconds into a rivalry game against UNC. Duke lost the game 88-72.

Mike Kzryzewski said Williamson's knee was stable, and that the team would provide a timetable for his recovery on Thursday.

Williamson was wearing a pair of Nike PG 2.5's, Paul George's signature sneaker from last fall, during the blowout.
