The Big Bang Theory and Fox's NFL game sit atop Thursday's ratings, and Legacies showed some growth in its second week on The CW.

The CBS comedy was down week to week in adults 18-49 (2.1, tying its season low, vs. 2.3 last week), but its 12.43 million viewers will likely end up as the biggest tally of the night. Young Sheldon (1.7), Murphy Brown (0.8) and SWAT (0.7) all matched their week-ago ratings, while Mom dipped slightly to 1.1. 

Episode two of Legacies scored a 0.4 in the 18-49 demo, up from 0.3 for its premiere a week ago. Supernatural also ticked up to 0.4 on The CW.

Thursday Night Football slipped week to week on Fox, dropping a point in metered-market households (8.2 vs. 9.2). That's not much of a surprise, given that the game involved two teams (the 49ers and Raiders) at the bottom of the standings and was a blowout (the Niners won, 34-3). It's at 2.1 in adults 18-49 but will adjust up to the night's No. 1 ranking in the demo in the finals.

Grey's Anatomy (1.5) and Station 19 (0.9) both held steady for ABC, and How to Get Away with Murder (0.8) ticked up a tenth of a point. NBC's shows were all flat or down a tenth in the 18-49 demo, but all of them improved week to week in total viewers, with Superstore (0.8 demo, 3.27 million viewers) drawing its biggest same-day audience since March.

Fox leads the network standings with a 2.1 among adults 18-49, pending updates. CBS finished second at 1.2, a tenth ahead of ABC's 1.1. NBC averaged 0.8 and The CW 0.4.
