"I literally don't know," he tells Access Hollywood of his future on the show. "It would be nice to know if I'm supposed to report back soon."
Knight says he's received many phone calls from friends and fans who were concerned about his character's fate after the hit ABC show's finale, in which his unassuming Dr. George O'Malley failed his intern test. He says the producers have not told the actors what will happen next season.
Knight spent much of last season in the middle of a firestorm after costar Isaiah Washington used an anti-gay slur during an on-set argument with Patrick Dempsey. Shortly afterwards, Knight confirmed to PEOPLE that he is gay.
Speculation has also swirled around whether Washington will return next season.
Washington's rep, Howard Bragman, tells PEOPLE: "A contract has not yet been signed, but we have no reason not to expect it to be signed before the season begins."
In June, while the show is on hiatus, Washington will film the independent movie, The Least of These.
ABC has declined to comment.
