Duke is out of the ACC tournament after a positive COVID-19 test within the program, the conference announced Thursday morning.

The Blue Devils were scheduled to play Florida State in the ACC quarterfinals on Thursday.

The cancelation "follows a positive test, subsequent quarantining, and contact tracing within the Duke men's basketball program," a statement from the ACC read. "The team is adhering to the outlined protocols within the ACC Medical Advisory Group report, which is available on theACC.com."

Without the opportunity to advance and potentially win the conference tournament, the Blue Devils' streak of 24 consecutive NCAA Tournament appearances is in jeopardy.

"I feel deeply for our players, who have done a terrific job all season in taking care of each other and the team," Duke coach Mike Krzyzewski said as part of a statement released by the school. "I am extremely proud of their collective attitudes and effort, which could not have been stronger. We are disappointed we cannot keep fighting together as a group after two outstanding days in Greensboro. This season was a challenge for every team across the country and as we have seen over and over, this global pandemic is very cruel and is not yet over. As many safeguards as we implemented, no one is immune to this terrible virus."

Florida State will advance to the tournament's semifinal round to play the winner of Thursday's game between North Carolina and Virginia Tech -- a contest that will now tip at 8:30 p.m. ET on ESPN.

Duke beat Louisville 70-56 on Wednesday to keep its NCAA Tournament hopes alive. The Blue Devils moved into Joe Lunardi's Next Four Out in his latest Bracketology; they needed to beat Florida State and perhaps get another win to receive an at-large bid on Sunday.

"Unfortunately, after going an entire season with no positive COVID-19 tests among our men's basketball student-athletes and coaching staff, one member of our program tested positive following Wednesday's ACC Tournament game in Greensboro," Duke athletic director Kevin White said. "After working with our medical professionals and following Duke and ACC Medical Advisory Group health, safety, and contact tracing protocols, the student-athletes on our team are now in quarantine. Since last March when the pandemic started, we have listened to our medical experts and always put safety at the forefront of any determinations regarding competition. As a result, this will end our 2020-21 season. We wish every team still playing college basketball good health and the very best during the next few weeks."

Louisville (13-7, 8-5 ACC) announced all Tier 1 individuals within its program have tested negative for COVID-19 and that the team is "on a path to have the requisite consecutive days of negative tests to be able to compete in the NCAA Tournament."

With Duke (13-11, 9-9) dropping out of the ACC tournament, though, it's unlikely the Blue Devils will make the NCAA tournament. It would be their first NCAA tournament absence since 1995.

"While our season was different than any other that I can remember, I loved the 2020-21 Duke Basketball team and was honored to be their coach," Krzyzewski said. "We have not asked more of any team in our history, and they deserve enormous credit for handling everything like the outstanding young men they are."
