The Seahawks today signed Na'Shan Goddard, an offensive lineman who was on the New York Giants' practice squad.

Presumably, the Seahawks are going to announce they will place Chris Spencer on IR today, which Mike Holmgren intimated on Monday. Spencer's back has been acting up and it does not appear that it is going to improve any time soon. We'll get more information at Holmgren's noon press conference.
