June 8, 2007 -- Isaiah Washington will not be scrubbing in for surgery at Seattle Grace Hospital next season and he is not a happy camper.
"I'm mad as hell and I'm not going to take it anymore," Washington said in a statement released through his publicist, Howard Bragman.
ABC confirmed thecontract of the troubled actor will not be renewed.
The move was confirmed by two sources with knowledge of the situation, one of whom said, "It was a difficult year and this should come as no surprise to anyone."
Officials at ABC Television Studio, which produces "Grey's Anatomy," declined comment.
Even as Washington's star rose with the hit show he starred in, he faced allegations that he used an anti-gay slur to refer to "Grey's" co-star T.R. Knight.
He initially denied reports he used the slur, and raised eyebrows with a public statement at the Golden Globe awards.
"No, I did not call him a f--t," Washington said in front of reporters.
Knight appeared on the "The Ellen DeGeneres Show," saying that he was shocked by Washington's denial.
On "Access Hollywood," another "Grey's Anatomy" co-star, Katherine Heigl, said: "He [Washington] just needs to stop talking."
Earlier this year, Washington admitted using the slur, apologized and said he planned to meet with gay rights groups.
He then said he would check into a treatment center for psychological evaluation.
"I have begun counseling," Washington said. "I regard this as a necessary step toward understanding why I did what I did and making sure it never happens again."
