(CBS) With their roster depleted by injuries and inconsistencies, the Bears went to work on their off day with a series of moves.

The Bears on Tuesday officially signed veteran running back Joique Bell, who adds experience to a depth chart that’s now topped by rookie Jordan Howard. Second-year back Jeremy Langford is expected to miss several weeks with an ankle sprain suffered in Sunday’s loss to the Cowboys. Before Bell joined the fold, the Bears’ two healthy running backs had combined for 12 career carries, all from Howard.

Bell, 30, has tallied 22 career touchdowns and averaged 4.0 yards on 561 carries. He worked out with the Lions last week, his team of the past four seasons. Instead, he will now face the Lions on Sunday as a member of the Bears.

Additionally, the Bears signed veteran defensive lineman C.J. Wilson, a six-year NFL veteran who has played for the Packers, Raiders and Lions. Wilson has posted 101 tackles and 6.5 sacks, primarily playing the role of defensive end. His presence to the roster adds to a defensive line that has lost Eddie Goldman and Jonathan Bullard to recent injuries.

Cornerback Kyle Fuller was placed on injury reserve Tuesday, more than a month after a knee scope. Fuller can return after eight weeks on the list.

To make room on the roster, the Bears waived tight end Greg Scruggs and linebacker Jonathan Anderson. They also terminated the contract of tackle Jason Weaver and promoted linebacker John Timu to the active roster. Offensive lineman Colin Kelly was signed to the practice squad Monday.

Following a busy off day, the Bears return to Halas Hall on Wednesday in preparation for Sunday’s contest with the Lions. Chicago is seeking its first win over Detroit since Week 17 of the 2012 campaign, Lovie Smith’s final season as coach.
