At least I can't find any news of it other than WTIII's cryptic tweet the other day.
When the Seahawks IR players they usually don't delay on the decision. Maybe they are waiting until Monday to force the Rams to study up on Thurmond this week?
Or maybe this is a case of Seattle telling Thurmond that he won't play unless injuries strike Lane/Maxwell/Trufant, since Carroll (rightfully so) is adamant about not letting corners play if they aren't at 100% field speed.
Of course it's official.....the people of Seahawks.net have already spoken. Of course, if the team went by how the people here think, we wouldn't have our two Pro Bowl offensive linemen on the team anymore.
