The Bears are signing defensive tackle C.J. Wilson, his agents announced on Twitter.

Wilson, 29, spent time with the Raiders and Lions last season. He was released by the Saints in August.

He’s a veteran of 78 career games and 19 starts, and he’ll have a chance to contribute immediately on a Bears defense that’s dealing with multiple injury issues.

Wilson was part of a Bears tryout Tuesday that included running back Joique Bell, tackles Clay DeBord, Colin Kelly, and Arturo Uzdavinis, guard Austin Shepherd and defensive tackle Sealver Siliga. The Bears signed Bell to the active roster and signed Kelly to the practice squad.

The Packers selected Wilson in the seventh round of the 2010 draft and he played his first four seasons in Green Bay. He has 6.5 career sacks.
