Smoltz, Posada to the DL

For Smoltz, it's not serious. He'll only be out a couple weeks.

Posada could be a different story, though. Word is that it shouldn't be season-ending, but there could be some structural damage which could necessitate surgery. If it's just a strain, he would only miss a few weeks. My guess: something in between. You should prepare your team to be without Posada for at least a month - maybe more.
