TR Knight has confirmed that he’s leaving “Grey’s Anatomy.”

“Leaving ‘Grey’s Anatomy’ was not an easy decision for me to make,” Knight said in a statement. “I am extremely grateful to have had the opportunity to play this character and will miss my fellow cast and crew very much.”

Knight had previously asked to be released from his contract on the show, and in the season finale in May, his character, Dr. George O’Malley, flat-lined after being hit by a bus.
