The Seattle Seahawks signed cornerback Perrish Cox shortly after Walter Thurmond officially dropped his appeal of the four-game suspension he received for violating the league's substance-abuse policy.
Thurmond will miss Monday night's game against the New Orleans Saints, road games at the San Francisco 49ers and New York Giants and will be eligible to return the day after Seattle's home game against the Arizona Cardinals on Dec. 22, making him available for the regular-season finale against the St. Louis Rams and the postseason.
Thurmond was the Seahawks' nickel back before taking over in Week 11 for injured starter Brandon Browner, who is reportedly facing a one-year ban of his own for violating the league's substance abuse policy.
Suddenly shorthanded in the secondary, the Seahawks signed Cox, who was waived by the 49ers earlier this month. Cox was a fifth-round pick by the Denver Broncos in 2010 who was out of football in 2011 due to off-field issues. He signed with San Francisco in 2012 and played in 25 games as a reserve before being released Nov. 12. Cox has 71 tackles and one interception in 40 career games, including nine starts.
Seattle also worked out former longtime Seahawk Marcus Trufant on Monday and reportedly reached out to Antoine Winfield, the 36-year-old who was released by Seattle at the end of training camp.
Byron Maxwell will start opposite Richard Sherman with Jeremy Lane filling the nickel role against the Saints.
