T.R. Knight is out and Katherine Heigl is still in as Grey’s Anatomy firms up its casting for its upcoming sixth season.
Knight confirmed he won’t be back in the role of Dr. George O’Malley by issuing a statement: “Leaving Grey’s Anatomy was not an easy decision for me to make,” Knight’s statement says. “I am extremely grateful to have had the opportunity to play this character and will miss my fellow cast and crew very much. I continue to wish them the very best, and wholeheartedly thank all of the fans of Grey’s Anatomy who have supported me and the show with such passion and enthusiasm.”
