S Donovin Darius won't be playing this week. The Jaguars fear that Darius has a torn ACL and will be lost for the season. Even in the best-case scenario that the knee ligament is only sprained, Darius will be sidelined for a few weeks. That means S Deke Cooper will move into the starting lineup against the New York Jets Sunday and may remain there for the rest of the season. does Cooper now become a good fantasy option ?
