Five-time Emmy nominee Sandra Oh has announced that she will depart Grey's Anatomy following its 10th season on ABC, ending in May 2014.
The actress said Tuesday, "It's such an interesting thing to play a character for so long and to actually get the sense that she wants to be let go as well."
"Creatively, I really feel like I gave it my all, and I feel ready to let her go."
"[Cristina] wants to be let go, and I am ready to let her go. We have to start the process, story-wise, for the writers to think of why she's going to go."
Oh signed a two-year extension with the series in May 2012, as did co-stars Ellen Pompeo and Patrick Dempsey, whose deals are also up next spring.
