That's how I remember it, too. The problem was that there was uncertainty when the Bills would host a playoff game, depending on the outcome of their final regular season game vs. Houston. Add to that the Bills were drubbed by the Oilers, were set to face them the next week without Kelly, and there was no chance of the game selling out in less than a week.
While blacked out playoff games are rare, every year there is always a scramble for wild card host teams to sell all their tickets in time. In 2009 the Vikings and Cardinals both struggled to sell out in time, and their stadiums seat around 64,000. If those teams had to fill an 80,000 seat stadium those games would have been blacked out.

However, some people never miss an opportunity to bash Bills fans.
I, too, was there on January 3, 1993.
