Duke's season has come to an unceremonious end. The Blue Devils program announced on Thursday that a positive test among Tier 1 personnel forced them to withdraw from the ACC Tournament ahead of a matchup against Florida State, and that the development will end their season.

"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. "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 2020-2021 season."

Duke had notched consecutive wins in the ACC Tournament over Boston College and Louisville before the positive test. A source told CBS Sports' Matt Norlander that it was a player who did not play against Louisville in the second round of the ACC Tournament who tested positive.

"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," coach Mike Krzyzewski said after the announcement. "I feel deeply for our players, who have done a terrific job all season in taking care of each other and the team.

"I am extremely proud of their collective attitudes and effort, which could not have been stronger."

Duke (13-11, 9-9 ACC) was on the outside looking in of the NCAA Tournament bracket in Jerry Palm's latest Bracketology prior to the news. It likely needed to win the league's postseason tourney to punch a ticket to the Big Dance, or at the very least needed a win over the Seminoles to make their bubble case more interesting.

The Blue Devils had several disruptions in their schedule this season related to the pandemic -- and made news by canceling part of their nonconference slate -- but none were nearly this consequential. Adding insult to injury, it went all season before its first positive test among Tier 1 personnel turned out to effectively be season-ending.
