With “The Big Bang Theory” now airing on Thursdays for the rest of the season, CBS’ Monday comedy lineup struggled to keep its numbers up, according to Nielsen overnight data.

“Kevin Can Wait” fared the best, holding even week-to-week with a 1.2 rating in adults 18-49 and 6.3 million viewers. “9JKL” (0.8, 5.1 million) was down by over 40 percent in the demo and nearly 30 percent in total viewers compared to last week. The Season 2 premiere of “Superior Donuts” (0.8, 4.8 million) was down by over 50 percent in both measures compared to the Season 1 premiere, which aired behind “Big Bang” last year. “Me, Myself, and I” (0.7, 4 million) was down again, this time by over 20 percent in the demo and over 10 percent in total viewers compared to last week. Though not a comedy, a new episode of “Scorpion” (0.7, 4.8 million) was also down in the demo. The drops mean that the entire lineup, save for “Kevin Can Wait,” posted series lows.

A drop was not unexpected, as “Big Bang Theory” has frequently been used by CBS as a lead in to help out other comedies in its lineup. But now that boost will go to “Big Bang Theory” prequel “Young Sheldon,” which will begin its regular run this Thursday.

For ABC, “Dancing with the Stars” (1.5, 10.1 million) was up in both measures. “The Good Doctor” (2.0, 10.9 million) was up slightly in the demo and was the top-rated and most-watched show of the night.

On NBC, “The Voice” (1.9, 9.4 million) was down slightly in the demo. “The Brave” (0.8, 4.7 million) dipped in both measures to a series low.

For Fox, “Lucifer” (0.8, 3.3 million) was even, while “The Gifted” (1.1, 3.5 million) ticked up in the demo.

On The CW, “Supergirl” (0.5, 1.8 million) was even and “Valor” (0.2, 1 million) ticked up in total viewers.

ABC won the night with a 1.7 and 10.3 million viewers. NBC was second with a 1.5 and 7.9 million viwers. Fox was third in the demo with a 1.0 but fourth in total viewers with 3.4 million. CBS was fourth in the demo with a 0.8 but third in total viewers with 5 million. The CW averaged a 0.4 and 1.4 million viewers.
