Williams started for Seattle in the team’s first 10 games of the season, before ultimately being released on Dec. 7. Before his release, Williams recorded 46 combined tackles and defended four passes in 2015.

He spent the last two years with the Philadelphia Eagles prior to signing a three-year, $18 million deal with the Seahawks last offseason, which included $7 million guaranteed.
A seventh round selection by the Titans in the 2008 draft, Williams has 352 combined tackles and 62 passes defended in seven NFL seasons.
