Duke freshman Cooper Flagg appeared to injure his left ankle after slipping under the basket and was helped to the locker room by two teammates late in the first half. He did not return.

Duke freshman phenom Cooper Flagg is a "real long shot" to play in the ACC tournament semifinals after suffering a sprained left ankle, coach Jon Scheyer said.

The Tar Heels kept chipping at Duke's lead, getting the 25 point-lead down to 12. Then under 10 and finally to one before the mistake at the end. UNC rode the back of Lubin who had 20 points in the game but also Cadeau who led a flurry late in that half.

North Carolina graduate forward Jae'Lyn Withers committed a lane violation with 4.1 seconds left that negated a tying free throw in the Tar Heels' loss to No. 1 Duke in the Atlantic Coast Conference T

Duke holds on to beat North Carolina 74-71 to advance to the ACC tournament final.
