NBC’s “Sunday Night Football” matchup between Pittsburgh and Baltimore was easily the top ratings draw on Sunday, while ABC was above average with the American Music Awards, but the kudocast tumbled to a record low.

On an overall lackluster night, all of the major networks were off from the same Sunday a year ago

Preliminary national Nielsen estimates for football are also subject to revision due to time zone differences, but the Ravens’ 13-10 victory over the rival Steelers averaged a 6.0 rating/15 share in adults 18-49 and 15.8 million viewers overall on NBC’s stations from 8:30 to 11 p.m. — winning each half-hour as usual. The game lost some of its luster without Steelers quarterback Ben Roethlisberger (who was out injured) and will come in below the “SNF” season average; still, it’s expected to deliver around 18 million viewers when the nationals come in Tuesday.

Elsewhere, ABC followed “America’s Funniest Home Videos” (1.7/5 in 18-49, 7.5 million viewers overall) with the three-hour “American Music Awards” (3.4/8 in 18-49, 9.5 million viewers overall). The awards show provided ABC with its best same-night 18-49 average of the fall (though it doesn’t figure to gain nearly as much in DVR playback as the net’s drama lineup typically sees), and was down 21% from last year’s 18-49 rating (4.3) to a record low.

Ratings are murky for CBS, which started its primetime lineup nearly an hour late in much of the country due to a late-afternoon NFL game that extended until about 7:52 p.m. ET. In the 8 o’clock hour, “60 Minutes” did roughly a 2.8/7 in 18-49 and 12.8 million viewers overall, followed by “The Amazing Race” at 9 (2.2/5 in 18-49, 9.6 million viewers overall) and “The Good Wife” at 10 (1.6/4 in 18-49, 9.5 million viewers overall).

Fox opened with a special repeat of “Bob’s Burgers” (1.3/4 in 18-49, 3.4 million viewers overall) and an original “The Cleveland Show” (1.6/4 in 18-49, 3.3 million viewers overall). From there, “The Simpsons” (2.5/6 in 18-49, 5.2 million viewers overall), “Bob’s Burgers” (1.8/4 in 18-49, 4.0 million viewers overall) and “Family Guy” (2.5/6 in 18-49, 5.1 million viewers overall) were on the low side, but on par with their delivery of two weeks ago (when it was also CBS, not Fox, that benefited from a football overrun). And at 9:30 p.m., “American Dad” (2.0/5 in 18-49, 4.2 million viewers overall) was up 11% vs. its most recent original.

Univision was paced by the two-hour finale of “Mira Quien Baila” (1.4/4 in 18-49, 3.6 million viewers overall).

Preliminary 18-49 averages for the night: NBC, 4.9/12; CBS, 3.0/8; ABC, 2.9/7; Fox, 2.0/5; Univision, 1.2/3.

In total viewers: NBC, 13.3 million; CBS, 12.6 million; ABC, 9.0 million; Fox, 4.2 million; Univision, 3.0 million.
