The Vikings are expected to sign journeyman CB Frank Walker, who has played for the Giants, Packers and Ravens in his seven-year career.
↵Word is that Chris Cook practiced today, but his status for Sunday has not been released.
↵Presumably, Walker will be 4th on the depth chart behind Antoine Winfield, Asher Allen and Lito Sheppard if Cook cannot play.
↵The Vikings cannot confirm that if Walker fogs a mirror when it is put under his nose it will be an upgrade over Lito Sheppard.
