RENTON - The third hamstring injury of the season for S Jeron Johnson proved to be the knockout blow.

The Seahawks placed Johnson on injured reserve Wednesday after suffering yet another hamstring injury Sunday against the San Francisco 49ers. Johnson had missed games on two separate occasions this season to pulled hamstrings. The newest injury was to his other leg and head coach Pete Carroll characterized it as a serious injury.

Seattle re-signed CB Perrish Cox to fill Johnson's spot on the roster. The Seahawks had signed Cox three weeks ago but released him after just one practice as it became apparent the appeal of CB Brandon Browner's suspension would be a more drawn out process.

Seattle elected to promote CB DeShawn Shead at the time instead of keeping Cox on the roster. Shead can play safety as well and will become the reserve at that position now with Johnson on injured reserve.

Injury Updates:

LB K.J. Wright had sugery on his injured right foot on Wednesday morning. Carroll didn't have an update on how the procedure went, but said Monday the injury will keep him out 4-6 weeks.

LB Malcolm Smith is expected to replace Wright at the weakside linebacker position in his absence.

C Max Unger participated in the team's walk-through on Wednesday morning but did not practice with the team. Unger left last week's game against the San Francisco 49ers with a pectoral strain. Carroll indicated they expect to have Unger back at practice by Friday and believe he'll be able to play Sunday against the Giants.

WR Percy Harvin did not practice with the team Wednesday. It's been over three weeks since Harvin made his debut for the Seahawks against the Minnesota Vikings. However, he's still not been able to return to practice since the initial appearance.

Carroll said they are still taking a week-to-week approach with Harvin and he is still working through soreness in his hip. Carroll said there is "new movement" in his hip that Harvin is still getting used to. He said Harvin has progressed and fallen off again over the last few weeks and they are still taking their time with his injury.
