Duke coach Jon Scheyer says it’s a “real longshot” that freshman star Cooper Flagg will be able to play in the Atlantic Coast Conference Tournament semifinals because of an ankle sprain.

A nightmare scenario is unfolding for the Duke Blue Devils. The No. 1 team in the country entered their first-round matchup of the ACC Tournament on Thursday against the Georgia Tech Yellow Jackets with confidence, but by halftime there was major reason for concern.

Duke star Cooper Flagg left his team's Atlantic Coast Conference Tournament quarterfinal game on Thursday with a left ankle injury and had to be helped to the locker room. The top-ranked Blue Devils were trailing by 26-17 late in the first half when Flagg went up for a rebound and crashed to the floor after he appeared to have his left foot land on the foot of Georgia Tech’s Darrion Sutton.
