No need to call 9-1-1 for “9-1-1,” but the first-responder drama slipped enough in ratings on Monday to allow NBC back into a first-place tie with Fox.

NBC and Fox tied for first in ratings, both with a 1.1 rating/5 share in the advertiser-coveted 18-49 demographic, according to preliminary numbers. NBC was second in total viewers with 6.5 million, Fox was fourth with 5 million.

For NBC, “The Voice” from 8 p.m. to 10 p.m. averaged a 1.4 rating and 7.9 million viewers. At 10, “Bluff City Law” managed a 0.5 and 3.6 million viewers.

For Fox, “9-1-1” at 8 had a 1.4/6 and 6.4 million viewers. At 9, “Prodigal Son” got a 0.8/3 and 3.6 million viewers.

It’s likely that ABC’s ratings are inflated a bit due to local broadcast markets carrying sister cable channel ESPN’s “Monday Night Football.”
