CHARLOTTE -- North Carolina will play in a game that might largely define its season Friday night in the Atlantic Coast Conference tournament semifinals. Yet the Tar Heels (22-12) aren't likely to be the main storyline when going against top-ranked Duke. The Blue Devils (23-9) might be without ACC Player of the Year Cooper Flagg, the most highly regarded player in college basketball this season. Flagg sprained his left ankle during Duke's quarterfinal victory against Georgia Tech on Thursday after landing on an opponent's foot in the first half. He didn't return to action, leaving him with a season-low two points.
