Underhill: Saints are interviewing probably 12 coaches (Tracker: officially 7 interviews) [Rapoport: Saints may add more]

I heard on the radio that the earliest the Saints could interview Aaron Glenn for a second time was on Monday January 20. Is that assuming a Lions loss, or can they still interview for a couple of days during the playoffs? I thought all contact was supposed to be stopped, but I may have misunderstood.
