The Arizona Cardinals' overtime win over the Green Bay Packers was the NFL's highest-rated Saturday prime-time divisional game since it began 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 only to the 34.2 million for Broncos-Patriots in 2012 for the time slot.
