Mack said he didn't believe the high rate of positive tests came from his players being irresponsible:
"Again, who knows how it was contracted, but I know it wasn't because of our guys' foolishness, or breaking curfew, or anything like that. By and large, our guys have done a great job. Knock on wood, 90 percent of our team's had it, and recovered thankfully. Unless something crazy would happen, I think the better part of the team has already had it, and doesn't have to worry about it from here on out."
Louisville and NC State postponed their scheduled game on Wednesday.
"The postponement follows positive tests, subsequent quarantining, and contact tracing within the Louisville men's basketball team," the ACC said in a statement.
After two weeks out of action, Louisville is set to return to the court for an ACC/Big Ten Challenge matchup against Wisconsin on Saturday, Dec. 19 at noon ET.
Mack explained why Louisville had to postpone the NC State game despite resuming practice this week:
"We decided that we just simply couldn't play the game against NC State. We didn't have enough available players. So, I think when people say, 'Well why? Why not? You resumed practice?' Doesn't mean all your individuals are back to practice. It just means the ones that are back were determined to be not direct contacts and had enough negative tests in order to return to the court. So, we didn't return as a whole unit when we began practicing this past Saturday. We're still in the process of getting players back at various stages, I'll leave it at that."
Mack said the game against the Wolfpack will be rescheduled because it is a conference game.
"We have plenty of time, we're in the middle of December," Mack said. "I'm sure there are going to be cancellations and postponements as we move throughout the conference season. ... I'm sure our administrations are doing everything they can to figure out the date."
The No. 23 Cardinals have played four games this season and are undefeated, with wins over Evansville, Seton Hall, Prairie View A&M and Western Kentucky.
