Bears cornerback Terell Smith suffered a knee injury in Sunday night's win over the Bills. The latest injury update isn't reassuring.

Smith was carted off Soldier Field after sustaining a non-contact injury covering a Buffalo Bills receiver. It looked as though Smith landed awkwardly on his knee, and went to the ground. Johnson said on Sunday Smith's injury was the most serious of the injuries the Bears sustained on Sunday.

A knee injury to third-year cornerback Terell Smith will test Bears depth at the position but it appears other injuries from Sunday's game are also a problem.
