Comedian Devon Walker has announced his exit from “Saturday Night Live” after three seasons, just days after creator Lorne Michaels teased a Season 51 cast shakeup. Walker, 34, shared the surprising news on Instagram Monday night. He compared his job on the NBC sketch comedy show to a relationship, and admitted that it was “toxic” at times.

After three seasons, Devon Walker has exited the cast of “Saturday Night Live.”

Walker is the first “SNL” cast member to confirm his departure ahead of season 51, although more exit announcements are likely coming. During an interview with Puck News published last week, “SNL” creator Lorne Michaels teased a big cast shakeup.
