Hedges was placed on the 7-day concussion injured list Thursday, Mandy Bell of MLB.com reports.
Hedges was scratched from Wednesday's lineup against the Orioles due to an illness, and the backstop is apparently dealing with a concussion that will force him to miss at least a week. Rene Rivera should see increased playing time behind the dish in his absence, while Ryan Lavarnway's contract was selected in a corresponding move to provide depth at catcher.
