In the previous episode of Bones it should have said something like 'coming up in 3 weeks' instead of next week. Like Raistlin said, your show wasn't postponed, it wasn't scheduled at all for this week. Every October this happens on FOX since they always run the baseball playoffs and World Series. So if you are a die hard Bones fan you should be used to this by now! There are only 22-24 episodes in a season so this is just two less weeks of reruns in the spring or something.
