Last night’s overtime NFC Divisional Playoff game between The Green Bay Packers and Arizona Cardinals has posted an 18.8/33 household rating to rank as the highest-rated Saturday primetime Divisional game ever, according to Fast National data from Nielsen. In viewers, the telecast averaged 33.7 million, making it the second-most watched Saturday primetime Divisional ever, after the 34.2 million viewers for Broncos-Patriots game on CBS January 14, 2012.

The household rating and viewership for the Packers-Cardinals game are up 9% over last year’s primetime Saturday NFC Divisional Playoff (17.2/29 and 31.0 million viewers for Panthers-Seahawks on FOX). The NFL introduced primetime Saturday Divisional Playoff games in the 2001 season.
