NEW YORK -- The Cardinals' overtime playoff win over the Packers was the highest-rated Saturday prime-time divisional game since the NFL instituted the time slot in 2001.

NBC said Sunday that Arizona's wild 26-20 victory averaged an 18.8 rating and 33 share. The 33.7 million viewers were up 9 percent from last year's Panthers-Seahawks matchup and second for the time slot only to the 34.2 million for Broncos-Patriots in 2012.

Ratings represent the percentage of homes with televisions tuned to a program, while shares measure the percentage of TVs in use at the time.
