The Vikings aren’t done signing free agents.  They’re now looking for help at defensive end, which is a little thin with Erasmus James recovering from a third knee surgery and Kenechi Udeze dealing with leukemia.  One possibility is Tennessee free agent Antwan Odom, who visited Cincinnati yesterday and has no plans yet to come to Winter Park in Eden Prairie.  Still on the market is Jevon Kearse, who just released by the Eagles after battling injuries over four seasons.
