Duke star forward Cooper Flagg will be absent for his team’s ACC tournament semifinal showdown against archrival North Carolina Friday after an ankle injury suffered in the Blue Devils’ 78-70 victory over Georgia Tech on Thursday.

Following Saturday's ACC Championship win over Louisville, the Blue Devils didn’t pass up the opportunity to take a jab at their biggest rival, North Carolina, whom they beat three times this year. "Try ACC champs or The Brotherhood if you are still struggling w/ it today?" they posted on social media.

North Carolina just blew its shot at the ACC Tournament championship game in perhaps the worst way possible. With just 4.1 seconds left in the semifinal matchup against No. 1 seed Duke on Friday, UNC was called for a lane violation on a potential game-tying free throw.

The thrill of victory and the agony of defeat. That's what defines college basketball in March. On Friday night, North Carolina fans felt the latter when the team blew a prime opportunity to complete a massive comeback over rival Duke in the ACC Tournament semifinal.
