LAKE FOREST, Ill. -- The Chicago Bears placed former first round pick cornerback Kyle Fuller on injured reserve, signed running back Joique Bell and defensive lineman CJ Wilson, elevated linebacker John Timu to the active roster, and waived linebacker Jonathan Anderson and tight end Greg Scruggs, the team announced on Tuesday.

Fuller, whom the Bears claimed underwent a routine knee scope in the preseason, started 30 of 32 games for the Bears in 2014-15, intercepting six passes and forcing three fumbles. Ex-general manager Phil Emery selected Fuller 14th overall in the 2014 NFL draft, but current defensive coordinator Vic Fangio hinted last year that the club expected more out of the Virginia Tech product.

So far in 2016, the Bears have used Jacoby Glenn, Deiondre' Hall, Bryce Callahan and Cre'Von LeBlanc at the cornerback/nickel back spots, alongside veteran defensive back Tracy Porter.

Meantime, Bell has 2,234 career rushing yards on 561 attempts with 22 rushing touchdowns. He's appeared in 68 games (15 starts), primarily for the Detroit Lions from 2012-15. The Bears are thin at running back after Jeremy Langford suffered a right ankle sprain that is expected to sideline him 4-6 weeks. Reserve tailback Ka'Deem Carey is also battling a hamstring injury, and was inactive in Week 3.

Wilson spent time with the Lions, Oakland Raiders and Green Bay Packers, where he accumulated a combined 111 tackles, 6.5 sacks and 15 tackles for loss.

An undrafted free agent in 2015, Timu started three games at linebacker last year, but opened the '16 season on the practice squad. Timu takes over for Anderson, who also played linebacker as an undrafted rookie last season (three starts).

Scruggs, a four-year NFL veteran, was active in each of the first three games.
