The Minnesota Vikings continue to consider the former Army Ammunition Plant site in Arden Hills as a possible site for a new stadium.  Vikings Vice President Lester Bagley tells the St. Paul Pioneer Press the site is "very viable."  The Vikings are also considering other options.  The Vikings lease at the Metrodome expires following the 2011 season.  Viking linebacker E.J. Henderson has been added to the NFC Pro Bowl roster.  He broke his leg in December of 2009 but played all this season after a lengthy rehabilitation.
