Duke University’s men’s basketball success over the years—the national championships, the Final Four appearances, all the NBA players who’ve honed their craft down in Durham—has created a blue-chip brand.

Duke’s Cooper Flagg, the ACC’s player and rookie of the year, appeared to injure his left ankle Thursday during the top-ranked Blue Devils’ ACC tournament opener in Charlotte. Flagg came down awkwardly on the foot of Georgia Tech’s Baye Ndongo while pulling down a rebound late in the first half.
