9-1-1: Lone Star debuted on Fox as a spinoff of the successful 9-1-1, but there was no saying how the new show would do with so few connections to the parent series compared to other TV shared universes.
When the show landed a couple of big-name actors in Liv Tyler and Rob Lowe to star and scored a second season coming off of great ratings in Season 1, however, the future seemed bright.
Sadly, one star is now leaving the show ahead of Season 2.
