RENTON, Wash. (AP) -- The Seattle Seahawks returned from their bye week and placed cornerback Marcus Trufant on injured reserve with a back injury that will end his season.
Trufant was injured in Seattle's Week 4 loss to Atlanta. Coach Pete Carroll said Trufant suffered a bruised sacrum -- a triangular bone at the base of the spine -- and Trufant was so sore he was unable to bend over and tie his shoes before Seattle's win at the New York Giants in Week 5.
Trufant was replaced in the lineup against the Giants by second-year cornerback Walter Thurmond. Trufant is the longest-tenured Seahawk, having spent all his nine NFL seasons in Seattle.
To fill Trufant's roster spot, the Seahawks signed defensive tackle Jason Shirley.
