This is the Seahawks' release:
The Seattle Seahawks have signed tackle Kyle Williams to the active roster from the practice squad. Williams is a second-year player from USC, acquired by the Seahawks as a free agent in 2007.
In order to make room on the roster for Williams, the Seahawks released tight end Jeb Putzier, who joined the Seahawks as an unrestricted free agent from Houston this off-season. Putzier was active in seven games for the Seahawks this season and had no catches.
