Williams will be a fourth-year player in 2016. He has appeared in all 48 games since the Bengals selected him in the third round of the 2013 draft. He started four games in 2015, three of which were in place of an injured Iloka and the other was when Cincinnati employed a three-safety alignment in the Nov. 1 game at Pittsburgh.
Williams had an interception in the fourth quarter against Steelers quarterback Ben Roethlisberger to set up the Bengals’ game-winning touchdown drive.
Terms of of Nelson’s deal with the Raiders have yet to be announced.
