We don’t yet know for sure when AMC companion series Fear The Walking Dead will return for Season 3, but there’s more uncertainty on the horizon. Showrunner Dave Erickson will step down after the Walking Dead spinoff’s third season, moving on to other AMC projects.

Per The Hollywood Reporter, series showrunner and executive producer Erickson will leave Fear The Walking Dead behind after Season 3, which itself will run the full 16 episodes of its progenitor. The series has not yet been renewed for Season 4, nor has a new showrunner been chosen to replace Erickson.

If nothing else, Erickson will remain an executive producer on Fear, and continue at AMC with a multi-year deal developing new series. Says AMC:

We’re beyond grateful for Dave’s amazing work on the first three seasons of Fear the Walking Dead. With Dave as showrunner, the series fulfilled its creative promise to expand the Walking Dead universe in a way that was totally unique from the original series, and has gone on to become the No. 2 drama series in ad-supported cable, behind only The Walking Dead. We are also incredibly excited that Dave has chosen to stay in the AMC family to pursue his next passion project. We look forward to many more successful collaborations.

Of course, The Walking Dead has had its share of showrunner exits; most famously with Frank Darabont in Season 2, and subsequently Glen Mazzara. Here’s to more peaceful transitions, and a Fear The Walking Dead Season 3 date coming soon.
