It marked the fourth consecutive missed game for Williamson, who leads the fourth-ranked Blue Devils in rebounding, blocks and steals and is their second-leading scorer.
Coach Mike Krzyzewski said this past weekend that the Blue Devils "can't and won't" rush Williamson back onto the court until he's fully healthy.
Williamson suffered a Grade 1 knee sprain on the first possession of a loss to North Carolina two weeks ago. Without him in the starting lineup, Duke has beat Syracuse and Miami but lost to Virginia Tech.
