Fast affiliate numbers for Sunday Night Football weren't quite up to the level of last week's record haul, but the game between the Detroit Lions and San Francisco 49-ers still managed to bring in an easy win for NBC. After a 90-minute block of Football Night in America (a 4.8 rating with adults 18-49), non-time-zone-adjusted numbers give the game a 7.5 rating among adults 18-49 and 18.1 million viewers. From last week's fast national, that's a 23 percent drop in the demo.

For the night, NBC averaged a 6.5 adults rating and 15.7 million viewers.

CBS benefited from NFL overrun until roughly 7:37 p.m. After that, a new episode of 60 Minutes posted a 3.2 adults rating and Big Brother was even with last week's 2.3 adults rating. Adding in encores of The Good Wife and The Mentalist, CBS averaged a 2.5 rating with adults 18-49 and 8.98 million viewers.

NFL overrun also influenced Fox's fast score -- a 2.0 rating with adults 18-49 and 4.5 million viewers -- with animation encores filling the schedule after football.

Univision posted an average 1.0 rating with adults 18-49 over the course of the night, while a repeat of America's Funniest Home Videos and a block of Revenge encores gave ABC a 0.7 adults rating and 3.5 million viewers.
