The Seahawks have signed free agent Perrish Cox to help fill their sudden need for cornerbacks.
Looking forward to the next chapter in my NFL career as a member of the Seattle Seahawks!!! Can't wait to get back on the field!!#GoHawks— Perrish Cox (@pcox16) November 26, 2013
Seattle announced the move Tuesday afternoon, shortly after Walter Thurmond's suspension became official. Thurmond will miss Seattle's next four games while Brandon Browner is reportedly facing a one-year ban, each player having allegedly violated the league's substance-abuse policy.
Cox, 26, was a fifth-round pick by the Broncos in 2010 and started nine games as a rookie. He spent the last two seasons as a backup with the 49ers, who released him earlier this month.
Thurmond will be eligible to return for Seattle's regular-season finale and the postseason.
Coach Pete Carroll said Monday that Antoine Winfield is an option, and the team has reportedly been in contact with the 36-year-old free agent. Seattle reportedly worked out longtime Seahawk Marcus Trufant on Monday, while Tharold Simon and DeShawn Shead are the team's in-house options.
