Training camp "officially" ended last week. Practices are now closed to the public.

None of Seattle's three starting linebackers were on the field for practice as David Hawthorne, Leroy Hill and Aaron Curry all have knee injuries. Different injuries, but all to the same joint. Curry and Hill are expected to be OK to play by the time of Saturday's game, but Hawthorne is unlikely to play.

LT Russell Okung worked in some individual drills, but isn't considered a candidate to play Saturday in Denver. RCB Walter Thurmond returned to practice after missing more than two weeks because of an ankle injury. He did some limited work in team drills, and coach Pete Carroll indicated he might be ready to play in Denver. There have been a lot of questions about the depth chart at right cornerback, and according to the team-issued depth chart, Thurmond is the first-unit corner, Kelly Jennings is No. 2 and Brandon Browner No. 3.

• TE John Carlson remains out with a sore shoulder, but Carroll indicated there has been improvement. Carroll described the injury as a "labrum issue" last week, and that injury is not insignificant. It's worth keeping a close eye on that.

• DE Pierre Allen remains out. DE Dexter Davis and DE A.J. Schable also did not participate in practice.

• SS Kam Chancellor did not practice because of a sore foot, which Carroll described as a soft-tissue injury. His status is day to day.

There was some question whether the addition of David Vobora was a reflection on Aaron Curry's future with the team, but it's more accurate to say that Vobora was acquired with an eye toward filling the role Will Herring had last season, a player capable of playing all three linebacker spots in addition to being a special-teams staple.
