A Pair of Grey’s Scoop! Regan Cellura June 17, 2009 Greys Anatomy 10 Comments Michael Ausiello has a pair of Grey's Anatomy scoop! TR Knight is officially out as Dr. George O'Malley and Jessica Capshaw is a series regular as Dr. Arizona Robbins. Knight may even have another gig already lined up. Fall's still months away, but one of last season's bigger Grey's Anatomy cliffhangers has already been resolved: Sources confirm to me exclusively that T.R. Knight's wish to be released from his contract has been granted. The official decision, I'm told, came down in the past few days, just as many of his castmates began receiving their formal pickup letters from ABC. Fans of Grey's know that there has been plenty of speculation over TR Knight's status with the show when the news hit the net that he wanted out of his contract three years premature. As for Capshaw, it looks like Callie's (Sara Ramirez) love interest and love life are still going strong with Capshaw signing on as a series regular.
