CBS announced today that it was reworking its schedule starting in March. Rules of Engagement (the new Yes, Dear) will be back for its fourth season on Monday, March 1st replacing Accidentally on Purpose. On March 31st, Accidentally on Purpose will take over Gary Unmarried’s Wednesdays at 8:30p timeslot because the show will have finished its season the week beforehand. Which means the chances of Gary Unmarried getting a third season are not looking good because it is rare that a show that ends before May sweeps will be back in September. Another show whose future looks dim is Numb3rs who had their season order cut and that show will be replaced by Miami Medical on April 2nd. I saw the first two episodes of that show and I think that CBS would be better off airing Three Rivers on Fridays at 10p over Miami Medical because it is a much better show.
