There’s a major shakeup on Shonda Rhimes’ upcoming midseason drama The Catch.

EW has learned the show’s creator and showrunner Jennifer Schuur is leaving due to “creative differences” over the direction of the show.

Schuur’s lieutenant on the show, writer Josh Reims, is also out.

We’re hearing Rhimes is eyeing Grey’s Anatomy and Scandal veteran Allan Heinberg to take over the series as showrunner.

With this new series, Rhimes will expand her production empire to four prime-time dramas—Scandal, Grey’s, How to Get Away with Murder and The Catch. Just last week, reporters asked Rhimes if she risked over-extending herself by managing four dramas, and she praised Schuur’s handling of The Catch as part of her answer. “Jennifer Schuur is very good at what she’s doing,” Rhimes said at the Television Critics Association’s semi-annual press tour in Beverly Hills. “She is running along. We are doing what we do, which is helping the bird fly and holding the baby a lot. But it’s not the same as running my show, which is making sure the scripts are good and making sure everything is running on a day to day basis and being boots on the ground, which is what happens on your show … So I will not have four shows on the air. Shondaland will have four shows on the air. I will have two shows on the air. [HTGAWM showrunner Peter Nowalk] will have a show on the air, and Jen will have a show on the air.”

The Catch follows Alice Vaughan (Mireille Enos), a fraud investigator who is poised to be the victim of a fraud by her fiancé. Between cases, she’s determined to find him before it ruins her career. The drama also stars Peter Krause and Sonya Walger.

The new series is expected to take over HTGAWM’s 10 p.m. slot on Thursday nights in midseason.
