According to
Broadcasting & Cable Fox has decided to hold Standoff hostage until June. The show was suppose to come back Friday, April 6th at 8p, but Fox has decided instead to stay with House repeats in that timeslot. Even though Fox is airing the first season of House on Fridays, I think they need to be careful not to over air the show.
Fox has said that Ron Livingston's show is not canceled, and its fate for next season has not been decided. But let's be real the writing is the wall and this hostage negotiation went very badly.
