Mon, Sep 17 Davis suffered a concussion Sunday against the Rams, Rich Campbell of the Washington Times reports. Recommendation: Coach Mike Shanahan noted Monday that Davis is in line to be subjected to the NFL concussion's protocol after absorbing a helmet-to-helmet hit Sunday. If Davis is forced to miss any action, starting with Sunday's game against the Bengals, then Niles Paul (three catches for 13 yards Sunday) would presumably be next in line for the Redskins' tight end targets.
