I'm taking my talents back to Chicago. So happy to be back. Never wanted to leave.— Kahlil Bell (@KahlilBell32) September 15, 2012
Bell was cut by the Bears in the preseason. He's played in 20 games for the team since 2009, rushing for 557 yards on 119 carries in his career.
The Bears will reportedly be without Forte, who sprained his ankle in the third quarter of Thursday's loss to the Green Bay Packers, for up to six weeks. Backup Michael Bush will get the bulk of the carries and he'll be backed up by Armando Allen. Bell will be the third-string running back.
