With McCann and Pena both banged up, it seems likely a catcher will have to be brought up... O'Brien from the AJC thinks it'll be Salty, though Corky Miller is also a possibility.
EDIT: According to Shanks, Salty's already at the ballpark. I guess that answers that.
Not clear yet who's being demoted/DL'd to make room for him.
EDIT #2: It's now being reported that while Salty is at the park, it's considered precautionary for now. They want to see how McCann and Pena handle BP before making a decision.
