Thursday practice and injury notes
Surgery for Garza
Veteran guard Roberto Garza will undergo arthroscopic surgery on his knee and won't play Sunday.
Coach Lovie Smith would not speculate how long Garza might be sidelined. Garza's injury, however, is a factor in offensive line coach Mike Tice possibly moving left tackle Chris Williams to left guard.
Williams is just returning from a hamstring injury he suffered against the Cowboys on Sept. 19.
''Hopefully, we can get [Garza] back before long,'' Smith said. ''But right now, he has been trying to work through it. But we feel like it's not getting better and we need to get it taken care of, so we'll be doing that shortly.''
Jay won't change
Smith said Jay Cutler won't change the way he plays because of his concussion.
''Of course we let him play the way he normally plays,'' Smith said. ''As far as being careful, no, you can't play football being careful. You always trying to play smart ball. If there's a time for a quarterback to run out of bounds or slide, they'll do that. But you can't think about anything else.
''We're going to protect Jay better and hopefully our running game will help out some also, and let him just play his brand of ball.''
Linebacker Lance Briggs (ankle), safety Major Wright (hamstring) and cornerback Charles Tillman (calf) did not practice Wednesday. Brian Urlacher's participation was limited because of a groin injury.
• Smith would not say if Todd Collins or Caleb Hanie would be the backup quarterback against the Seahawks on Sunday.
