The planted spinoff episode of Chicago P.D. last night won the 10 PM hour with a 1.4 rating in 18-49 and 6.8 million viewers (Live+same day), up a tick in the demo from last week.

Chicago Justice stars Winchester, Carl Weathers, Nazneen Contractor, Joelle Carter and Ryan-James Hatanaka. Wolf, Peter Jankowski, Matt Olmstead, Derek Haas, Michael Brandt and Arthur ‎Forney executive produce for Universal Television and Wolf Entertainment.

Chicago Justice joins NBC comedy pilots Trial & Error and Powerless, which also have been picked up to series.
