Per Jaz Glazer of Fox Sports, Kirk Morrison has signed with the Buffalo Bills. If the Raiders wanted to bring in a linebacker, they are down to Lofa Tatupu as the only remaining serviceable option. The Raiders were already thin at linebacker before losing Travis Goethel for the season to a knee injury. Behind starters Kamerion Wimbley, Rolando McClain and Quentin Groves the Raiders have Sam Williams, Darryl Blackstock, Bruce Davis II, Bani Gbdayu and Chris Francis. That's an extremely thin group of linebackers and the Raiders will be looking at cuts around the league to shore up the group.
