Cox was released by the Seahawks on Tuesday, Curtis Crabtree of Sports Radio KJR reports.
Cox was one of eight Seahawks to get cut on Tuesday. The veteran signed with the team in mid-January, as he figured to compete for a reserve position behind starters Richard Sherman and Jeremy Lane. However, Cox's value was greatly depleted after the team drafted four different defensive backs two weeks ago. Back on the market, Cox figures to draw some interest from teams looking to bolster their secondary with a veteran presence.
