(NEW YORK) -- Sandra Oh is on the go. She's announced that she will leave Grey's Anatomy after its upcoming 10th season.
The original cast member, who plays Dr. Cristina Yang, tells The Hollywood Reporter, "Creatively, I really feel like I gave it my all, and I feel ready to let her go."
Oh says she informed series creator Shonda Rhimes of her decision at the conclusion of the most recent season. However, she didn't let her co-stars know until Tuesday, when they were reading the script for the show's 200th episode.
How Oh's character will be written off the show remains to be seen.
Grey's Anatomy returns September 26 on ABC.
