During the regular season, the home team that hopes to avoid a blackout can buy any unsold tickets at 34 cents on the dollar. In the playoffs, there’s no such luxury.
According to the league office, the ability of the host to pay the “Visiting Team Share” evaporates in the postseason.
This means that the Colts, Bengals, and/or Packers can lift the blackout by purchasing any unsold tickets at full prices. Which makes it far less likely to happen.
With only two of 256 regular-season games blacked out, the possibility of up to three blackouts of postseason games could create a major political and P.R. headache for the league -- especially in cities like Indianapolis and Cincinnati, where taxpayer money was used to build the local NFL venues.
