RENTON - Head coach Pete Carroll hinted during his press conference Wednesday morning that the neck injury suffered by backup center Lemuel Jeanpierre may be potentially serious. 

That notion was confirmed Wednesday afternoon as the team placed Jeanpierre on injured reserve. 

Jeanpierre had been sidelined for the last week or so due to the injury. He did not participate in the team's preseason finale against the Oakland Raiders last Thursday night. 

The move is a blow to Seattle's offensive line depth. Jeanpierre is a very solid center and guard option that has played well in his prior opportunities.  The team will now have to turn to Stephen Schilling to serve as their backup center.

In Jeanpierre's place, the team re-signed receiver Phil Bates to their active roster. He was released in favor of Bryan Walters on Monday. Seattle now has eight receivers on their active roster. 

Seattle made some changes to their practice squad. The team signed guards David Arkin and Drew Nowak, and linebacker Allen Bradford to their practice squad and release guard Nate Isles, receiver Chris Matthews and safety Terrance Parks.
