The Seattle Seahawks have placed cornerback Walter Thurmond on injured reserve and claimed cornerback Ron Parker off waivers (Oakland), the team announced this afternoon.

Parker went to training camp with Seattle and spent time on its practice squad until being released on September 22. He signed with Oakland on September 26 and played in three games before being released on October 23.
