So those who were hoping Jake Peavy might manage to bring back a nice prospect or two should the White Sox fall out of contention before the trade deadline might want to reassess their hopes.

So there you have it. Doesn't really seem like this is a pitching related injury, as that would be kind of ridiculous. Non-displaced means exactly what you think it means, that the fracture didn't move out of the normal alignment of the rib, so that's good news at least. The bad news is that there is nothing you can do to treat a rib injury other than literally just do nothing. So Peavy needs to just rest and take things easy over the next month, which is something he's never been very good at.
