Duke Freshman sensation Zion Williamson is day-to-day with a Grade 1 knee sprain he suffered less than a minute into Wednesday's loss to North Carolina, the school announced on Thursday.
Williamson grabbed his right knee in pain after slipping awkwardly and falling when his left shoe fell apart as he planted hard while dribbling near the free throw line. The blue rubber sole ripped loose from the white shoe from the heel to the toes along the outside edge, with Williamson's foot coming all the way through the large gap.
Williamson, the ACC's second-leading scorer at 22.4 points per game and arguably the most exciting player in college basketball, walked off with a slight limp but under his own power before heading back to the locker room with no shoes on his feet.
North Carolina took advantage of Williamson's absence to beat the Blue Devils 88-72.
Duke is four years into a 12-year deal with Nike as the exclusive supplier of uniforms, shoes and apparel. The private school didn't disclose terms of the 2015 contract extension.
Nike has had an exclusive deal with the university since 1992.
