The Seahawks placed rookie outside linebacker Kevin Pierre-Louis on injured reserve Friday, ending his season because of a shoulder injury he suffered in the game at Kansas City on Nov. 16. Pierre-Louis had become part of the regular rotation at linebacker while Bobby Wagner was out with a turf toe injury.
The Seahawks also claimed rookie cornerback Loucheiz Purifoy off waivers Friday from Indianapolis. Purifoy (5-foot-11, 190 pounds) left Florida after his junior year in 2013 to enter the 2014 NFL draft, but was not selected. He was signed by the Colts as a rookie free agent.
Purifoy went into the preseason competing with cornerback Marcus Burley before the Colts traded Burley to the Seahawks on Aug. 30 for a sixth-round draft pick in 2015.
Signing Purifoy could mean that nickelback Jeremy Lane may be out longer than expected. Lane, who was on injured reserve for seven games with a groin injury, did not play Thursday because of a glute injury.
