Davis visited earlier in the week with Seattle officials. He is a seven-year veteran who played the last six seasons with the Arizona Cardinals after beginning his career with the Chicago Bears. He missed all but three games in 2005 with a torn biceps, but missed only one game in the four years prior to last season.
Len Pasquarelli of ESPN.com reports that the contract is for three years, but financial details are not yet available at this time.
In his career, Davis has amassed 246 tackles, 8.5 sacks and 11 passes defensed. He is regarded as a steady defender, solid at the point of attack, and very consistent when healthy.
