A "Saturday Night Live" cast member has been cast in a lead role in a Fox comedy pilot — which may mean the end is near for her run on the NBC comedy show, reports TVLine.com.

Abby Elliott will play a single mom in "Ben Fox Is My Manny," in which her character hires her brother to help raise her daughter, the story says. If the project is picked up to series, Elliott will have to leave "SNL," the story says.

Elliott is known for her “SNL” impersonations of Khloe Kardashian, Angelina Jolie and others, the story notes.
