The Seahawks on Friday made official a move that had been first reported as likely to happen earlier in the week, signing veteran defensive back Perrish Cox to a futures contract (which means he becomes part of the 90-man roster when the new league year begins on March 9).
Cox has 45 starts in 81 games in an NFL career dating to 2010, including playing in two regular season games as a reserve defensive back with Seattle late in the 2013 season.
Cox, who turned 30 earlier this month, had nine starts in 11 games this year for Tennessee before being waived.
