T.R. Knight Wants Out of "Grey's Anatomy"

The revolving door at Grey's Anatomy has taken another shocking spin.

Multiple sources confirm that T.R. Knight has asked to be released from his contract, a request that both ABC and Grey's show-runner Shonda Rhimes appear poised to grant. "They're working out the details now," whispers an ABC insider. (A network rep was unavailable for comment.)

There's no word on when Knight would make his final appearance, but, contrary to a report on the gossip blog crazydaysandnights.com, he has not walked off the show. "He's still working," maintains my Grey's mole.
