Duke coach Jon Scheyer is practicing extreme caution with all-American Cooper Flagg as the Blue Devils seek an ACC title. But the 6-9 freshman should be back for NCAA Tournament.

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.
