The postponement follows a positive test, subsequent quarantining and contact tracing in the Florida State program.
Duke announced Friday night that men's basketball coach Mike Krzyzewski would miss Saturday night's game at Florida State to quarantine following a COVID-19 exposure.
According to the university, Krzyzewski was exposed to a person, not in the Duke travel party, who tested positive for COVID-19.
At this time, Krzyzewski has not tested positive for the virus.
Associate head coach Jon Scheyer was set to serve as acting head coach before the postponement.
In December, Krzyzewski was outspoken about playing during the COVID-19 pandemic as cases surged in the state.

"I know the NCAA is worried about the endgame," he said. "They're not as worried about the game we're playing right now."
Duke women's basketball coach also echoed the men's basketball coach's statement saying, "I don't think we should be playing right now, that's my opinion on it."
