Lee suffered the injury in the first half of the loss to the Chicago Bears and tried to play through it but just couldn't tackle, so he left the game.
"One of my own guys caught me in a pile and later (I) got caught with my head down and I kinda slipped a little bit," Lee said. "I tried to keep coming back but I wasn’t really able to hit anybody. I hope I just bounce back and be ready for the next week."
In other injuries:
• Wide receiver/kick returner Dwayne Harris re-aggravated his pulled hamstring and missed a good portion of the second half.
• Linebacker Bruce Carter suffered a hamstring injury in the second half.
