Cooked or raw? If raw, it's unlikely to be a problem - and he should fully digest those by tomorrow (passing what little remains as normal poop). Cooked is a bit of a different matter, since cooked bones are brittle and liable to splinter. Even saying that though, it's no certainty that he would have a problem - and it's even likely that he won't.
Best thing to do really is just keep a good eye on him, see that he's eating, drinking and eliminating normally. If there seem to be any problems, see a vet.
