Duke's run in the ACC Tournament is over after a positive coronavirus test, the university said Thursday.

"SAD NEWS: We will not continue competing in the 2021 ACC Tournament due to our school’s and conference’s health/safety protocols. The determination was made following the positive COVID-19 test for a member of our program’s Tier 1 personnel after Wednesday’s game," the team tweeted Thursday morning.

The Blue Devils men's basketball team was set to play Florida State Thursday night. That game has been cancelled, according to the Atlantic Coast Conference. Duke (13-11) advanced to the quarfinals after a 70-56 win over Louisville on Wednesday night.

"The postponement follows a positive test, subsequent quarantining, and contact tracing within the Duke men’s basketball program. The team is adhering to the outlined protocols within the ACC Medical Advisory Group report," the ACC said in a statement Thursday.

Florida State will automatically advance to the semifinals and play the winner of Thursday night's North Carolina vs. Virginia Tech game, which has been moved up to an 8:30 p.m. tipoff.

"We have not asked more of any team in our history, and they deserve enormous credit for handling everything like the outstanding young men that they are," Duke Coach Mike Krzyzewski said in a statement.

"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 over yet," he said.
