RENTON - The CB Perrish Cox era with the Seattle Seahawks is over. It lasted one day.

Seattle signed Cox on Tuesday to take the place of CB Walter Thurmond, who was handed a four-game suspension for a violation of the league's substance-abuse policy.

The Seahawks apparently changed their minds in having Cox on the team and released him Wednesday to promote CB DeShawn Shead from the practice squad.

Seattle was already intending on promoting Shead from the practice squad and still signed Cox on Tuesday. In points toward some other reason leading them to change course.

The Seahawks are waiting on the appeal for CB Brandon Browner's impending suspension. Mike Garafolo of reported the appeal took place Wednesday and is now under review. If Browner wins the appeal, it could reduce, or possibly eliminate, any pending suspension.

Browner is likely to miss the next month anyway due to a serious groin injury. However, a lessened suspension could allow Browner to return by the end of the season or playoffs. It's still a possibility that Seattle can't wait on his injury to heal and he lands on injured reserve anyway. For now, the story continues.

Injury Updates:

Head coach Pete Carroll said that WR Percy Harvin did not practice during the team's workout on Tuesday. Carroll said that Harvin would get a light workload during practice on Wednesdy and that he feels they will have to manage his practice time the rest of the season.

However, Carroll said he expected Harvin to be full-speed after the bye week and there is no reason to think he wouldn't be able to play Monday night against the New Orleans Saints.

Carroll said WR Jermaine Kearse was back to practicing after suffering a concussion against the Minnesota Vikings and that no other player was expected to be limited in practice this week (besides Browner, who is still on the active roster and won't play).

**The injury report for Monday night games has to be reported to the league for Thursday, Friday and Saturday. Seattle practiced Wednesday in order to take the Thanksgiving holiday off. As a result, the Seahawks will wait until Thursday to release their practice report for today.
