And the wait for the One Chicago shows to return is nearly over, which presumably means some trailers will have to start releasing sooner rather than later. You can find all the One Chicago action back on the small screen starting on Wednesday, September 22 at 8 p.m. ET with the Chicago Med Season 7 premiere, 9 p.m. for the Chicago Fire Season 10 premiere, and 10 p.m. for the Chicago P.D. Season 9 premiere, all on NBC.
