Betrayal might be next on the TV chopping block.

The ABC drama, which already bowed to soft numbers last week, tumbled 27 percent to 4 million viewers and a 1.1 in the adults 18-to-49 demographic Sunday. ABC, which canceled Lucky 7 on Friday, also had a worrisome demo for Revenge (6.7 million, 1.9), which dropped 17 percent. Once Upon a Time (7.6 million, 2.5), however, was only down a tenth from last week.

NBC topped the night with Sunday Night Football (14.3 million, 5.7), while CBS' full lineup was delayed 44 minutes by the Broncos-Cowboys game.
