49ers' defensive line welcomes in Raiders' castoffs Arden Key and now Maruice Hurst

A week after the Raiders cut defensive linemen Arden Key and Maurice Hurst, they've headed across the bay, er, across state lines and agreed to join the 49ers. Hurst, a defensive tackle, announced Thursday on Twitter that he was joining the 49ers, a day after Key agreed to a one-year deal.
