On Monday, the San Francisco 49ers announced they signed cornerback Perrish Cox to a one-year contract. Cox previously played for the 49ers in 2012 and earlier this season, before being waived on November 12.
Cox takes the roster spot that was vacated by wide receiver Mario Manningham, who was recently placed on the Injured Reserve List. In 25 games with the 49ers, the cornerback recorded 18 tackles, two passes defensed and seven special teams tackles.
After being waived by the 49ers, Cox was signed by the Seattle Seahawks on November 26, only to be released the following day. He signed again with Seattle on December 11 and appeared in two games, recording three solo tackles.
The Seahawks likely signed Cox mainly for his knowledge of the Niners defense, although he was added after the announcement of the suspension to cornerback Walter Thurmond for substance-abuse violations. Cox was released after the Seahawks activated Thurmond, who recently finished his four-game suspension.
