The Seahawks plan to release DT Chris Cooper to make room for WR Deion Branch. They have until 1 p.m. PDT Saturday to officially submit this move. The expected move appeared briefly on the team's Web site today. Generally they do not officially make these moves until the last moment. Here is why: Let's say someone gets sick tonight or tomorrow morning, or someone is otherwise incapacitated. In that case they might feel the need to make a different move. I would bet they'll wait until tomorrow before making this move officially. But as we've said all along, they have been carrying 10 defensive linemen, a high number, and that is where they would presumably look first.
