NBC’s trio of “Chicago” dramas continued their strong run of performances, with “Chicago Med” leading the charge at a 1.4 and 9.5 million viewers, up 9% week-to-week. “Chicago Fire” and “Chicago P.D.” both came in even at a 1.3 and 9.1 million viewers, and a 1.2 and 7.8 million respectively.

The “Stumptown” season 1 finale failed to register much of a boost on ABC, coming in flat on last week at a 0.5 and 2.7 million viewers. Meanwhile “The Goldbergs” dipped 16% to a 0.9 and 4.7 million viewers. “Schooled” also lost ground from last episode, posting a 0.6 and 3.2 million viewers. “American Housewife” was even at a 0.6 and 2.8 million viewers.
