Seahawks cornerback Walter Thurmond has been placed on season-ending injured reserve, head coach Pete Carroll announced on Monday.
Thurmond will require surgery to repair an ankle injury that includes a leg fracture. A 2010 fourth-round pick out of Oregon, Thurmond had ascended to a starting role with veteran cornerback Marcus Trufant landing on injured reserve with a back injury.
Thurmond was injured during Sunday’s 6-3 loss to the Cleveland Browns and will be replaced on the 53-man roster by Ron Parker, an undrafted free agent from Newberry College who the Seahawks claimed off waivers from the Oakland Raiders. Parker went to training camp with the Seahawks and spent the first two weeks on Seattle’s practice squad before joining the Raiders.
Parker appeared in three games for the Raiders before he was waived so they could sign a kicker to temporarily replace Sebastien Janikowski.
