The Seahawks have acquired 25-year old OT Tyler Polumbus from the Lions.  No word yet on what the Seahawks had to give up.  Polumbus played in 15 games (8 starts) for the Broncos last year.  He has now played in 31 games (8 starts) in his two years in the NFL.  With Russell Okung banged up the Seahawks needed help at tackle and they probably got Polumbus for a nice price.
