Rumors have been swirling that after the whole Dr. Burke (Isaiah Washington) faggot thing? that T.R. Knight would be leaving the show. Well E! says that those rumors are false and for know, George is staying:

As I posted in the boards on Friday, this rumor is not true. I have spoken with reliable sources connected to the show, as well as T.R.’s personal publicist and the show’s ABC rep, and can tell you that T.R. is staying on the show. In fact, the ABC rep “irrefutably denies” the rumor. (And trust me, this kind of strong language would not be used if there were even rumblings of T.R. leaving.)
