'George' leaving Grey's Anatomy

T.R. Knight, who plays George on Grey's Anatomy, has asked to be released from his contract.

Entertainment Weekly's Michael Ausiello has been reporting in blind items for weeks that someone on the Grey's set was unhappy with their story line and wanted out of the show. Many fans were guessing it was Knight, who has seen very little screen time this season.

Ausiello's sources confirm that details are being worked out for Knight to leave the show.
