Raiders waived S Chinedum Ndukwe. The move clears a roster spot for fellow safety Jerome Boyd. A special teamer and reserve defensive back, Ndukwe notched two tackles in two games.

Raiders signed S Chinedum Ndukwe. Coach Hue Jackson is collecting former Bengals. Ndukwe will depth at the back end with Michael Huff and Matt Giordano coming off of concussions. He's been out of the league since the Bengals non-tendered him in March.

Free agent S Chinedum Ndukwe worked out for the Giants Thursday. The Giants let safety Michael Johnson walk as a free agent. Ndukwe can play in the box and would serve as a backup behind Kenny Phillips.
