Seahawks defensive end Chris Clemons returned to practice today, after sitting on Wednesday to nurse a sore ankle.
But both receiver Mike Williams (ankle) and Ben Obomanu (hand) remained out for a second straight day.
Those two not practicing was expected. The day head coach Pete Carroll was shooting for is Friday, so we'll see if both of those guys can get on the field tomorrow and see what they can do.
The Seahawks also made another roster move, signing offensive tackle Breno Giacomini to the active roster after releasing defensive end Clifton Geathers earlier this week.
Seattle also added another receiver to the practice squad, Dominque Edison, who was last with Tennessee. At 6-2, 200 pounds, Edison gives Seattle another big body at receiver.
Offensive coordinator Jeremy Bates said with Williams and Obomanu possibly out on Sunday, it will be important for another receiver to step up like Cameron Morrah did last week against Carolina.
"It could be Golden (Tate) this week; it could be Ruvell (Martin) this week," Bates said. "Guys just got to keep stepping up. It's the National Football League. We talk about it every week. There's going to be injuries, and we'll just see who makes it this week."
However, Bates said the personnel available while change how he calls the game on Sunday, depending on who's available.
"I think it changes based upon the defense that you're playing and somewhat your personnel," he said. "But at the end of the day we're in December. We've been kind of working on the playbook for a long time, so it's not like you're going to change it totally."
Bates also said it was nice to get Michael Robinson back in the lineup so they could run more two back sets.
