On Tuesday, July 29, ABC announced a change to the Season 9 premiere date. Below, we’ve gathered everything we know about 9-1-1 Season 9, from that date to its cast and much more.

From 'Dancing With the Stars' 34th season to '9-1-1' and spinoff 'Nashville' back-to-back.

Will 9-1-1 introduce Nashville in a backdoor pilot? Minear also shared with us in November that there won’t be a backdoor pilot on 9-1-1 to set up the new (at the time potential) spinoff.

9-1-1: Nashville will premiere on Thursday, October 9, at 9/8c, on ABC. (That’s a week earlier than previously announced.) It will follow 9-1-1 Season 9 and be followed by Grey’s Anatomy.

The world of 9-1-1 is officially expanding. The spinoff was a straight-to-series order, at which point it was revealed where it will take place.
