Grey’s Anatomy colleague and Katherine Heigl’s best friend T.R. Knight wants to leave “Grey’s Anatomy”. It’s too bad, his character George has always been one of my favorites and I would really mis him!

A person with direct knowledge of the situation has confirmed that T.R. Knight has asked to be released from his contract with “Grey’s Anatomy.”

The actor, who plays Dr. George O’Malley, has asked to leave the ABC medical drama because he is unhappy with his storyline, the person said. Knight has three years left on his contract and the network has indicated they will release him, said the insider, who could not be identified because they were not authorized to discuss negotiation details

An ABC representative declined comment.

Entertainment Weekly magazine first reported news of Knight’s request Tuesday in a posting at ew.com. Writer Michael Ausiello quoted a person at ABC who was not identified as saying that the show and “Grey’s” creator Shonda Rhimes were prepared to let the 35-year-old actor go.
