Update: After sliding to a 3.0 in the fast nationals for its second episode (which was adjusted up to a 3.1 in the finals), “Resurrection” fell an additional 17% in week three. According to Fast National data, Sunday’s episode posted a 2.5 adults 18-49 rating with 9.22 million viewers.

While it will rank as the top scripted program on network television Sunday, its rating seems destined to fall short of that delivered by CBS’ overrun coverage of the NCAA Basketball game.

ABC also offered “America’s Funniest Home Videos” (1.3, 6.74 million), “Once Upon a Time” (2.0, 6.61 million) and “Revenge” (1.6, 5.71 million).

Odds remain strong that ABC’s “Resurrection” will reign as Sunday’s top-rated network drama for a third consecutive week.

Its margin of victory, however, might be the lowest to date.

After dipping from an 8.5 to a 7.0 for last week’s episode, “Resurrection” this week posted a 6.2 overnight household rating.

Because its rating is still relatively strong–and because concept-driven dramas tend to endure big ratings drops across their first few airings–there is not yet reason to sound the alarm.

If “Resurrection” does not soon find stability, however, its status as a freshman hit will quickly come into question.
