Duke head coach Mike Krzyzewski made it official Monday during the ACC's weekly teleconference that he will not be able to coach Duke's game against Boston College on Wednesday. It's not clear if he'll be back for Duke's game on Saturday against Wake Forest, either.

Duke announced on January 1 that Krzyzewski had been flagged as a close contact of a COVID-19 case and would miss the Florida State game the next night, but that game ended up being canceled because of COVID-19 positives at Florida State.
