Isaiah Washington out on Grey's Anatomy

Isaiah Washington has lost his job on the hit ABC medical drama Grey's Anatomy, five months after creating a furor with his use of an antigay slur.

Washington's contract option was not renewed for next season, series producer ABC Television Studios said Thursday in Los Angeles.

''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, without elaboration.

He drew fire after using the antigay epithet backstage at the Golden Globe Awards in January while denying he'd used it previously on the set against cast mate T.R. Knight.

Gay rights groups and cast member Katherine Heigl, who publicly denounced Washington, were among his most vocal critics.

''This is something that will have changed the scope of his life,'' Heigl told Entertainment Weekly last month. Washington was ''sorry and embarrassed'' for the mistake, she said.
