WINSTON-SALEM, N.C. (AP) — Duke’s Mike Krzyzewski won’t coach in Wednesday night’s game at Wake Forest due to an undisclosed illness.

The school announced that the retiring Hall of Famer won’t be on the sideline due to a “non-COVID-related virus.” Associate head coach Jon Scheyer will be acting head coach for the eighth-ranked Blue Devils in this game.

Scheyer has been designated as Krzyzewski’s successor after this season. Scheyer coached the Blue Devils last season in a narrow win against Boston College.

That came as Krzyzewski and his wife followed quarantine protocols due to a family member testing positive for COVID-19.
