The school's athletic department made the announcement Friday.
The Bluejays (11-5, 3-2) have had three Big East games postponed because of COVID-19 issues in the opponent's program. Two have been rescheduled for February.
McDermott, 57, missed Monday's practice and part of Tuesday's for what was described as a "minor medical procedure." He was on the bench for the Bluejays' 87-64 home win over St. John's on Wednesday.
