Guess the doctor really has left the building. On June 7, ABC Studios confirmed that Grey's Anatomy star Isaiah Washington — whose character, Dr. Preston Burke, broke off his wedding to Dr. Cristina Yang (Sandra Oh) and skipped out in the May 17 finale — will not return to the show. The decision is the culmination of months of speculation after an ugly incident last fall, when Washington used the word "faggot" during an on-set disagreement with costar Patrick Dempsey, reportedly in reference to costar T.R. Knight. (The blowup prompted Knight to announce he was gay on Oct. 19.) Washington reignited the controversy by repeating the slur as part of a denial in front of reporters backstage at the Golden Globes in January.
