People reports that "Grey's Anatomy" star T.R. Knight, who has played George O'Malley since the show's debut, has asked producers to write him off the hit medical drama.
While details of his exit have yet to be ironed out, a source for the magazine says that it seems likely Knight's request will be granted and he will be released from his contract.
So why does Knight, who remains a fan favorite, want to leave?
"Have you seen the show lately?" says the source. Knight has received little screen time this season, with the show focusing on controversial storylines like the romance between Katherine Heigl's Izzie and her long-dead lover, Denny.
"It's time to move on," says the source. "It just feels like this is the right time to go."
