The list of notable Grey's Anatomy guest stars continues to grow. Joshua Jackson has been singed to a multi-episode arc on ABC's hit medial drama.

Elizabeth Reaser, Seth Green, Lauren Stamile and others have been announced as guest stars, as the new season continues to feature new faces.

Now it's Joshua Jackson, 29, who will reportedly play a doctor in the 11th episode of Season Four and continuing for several episodes. This is Jackson's first stint on TV since the end of his long-running hit show Dawson's Creek (2003).

We've looking forward to seeing Josh Jackson on Grey's Anatomy.
