The defense has survived, so far, the loss of six-time Pro Bowl middle linebacker Brian Urlacher and less serious injuries to linebackers Pisa Tinoisamoa (knee) and Hunter Hillenmeyer (ribs) that temporarily knocked them out of the starting lineup.

"I'm pleased with how the linebackers have stepped up," coach Lovie Smith said. "I mean, how many teams can go to their third middle linebacker (Nick Roach) and keep things running smoothly. Nick Roach has played well, I'm proud of Jamar Williams, Hunter Hillenmeyer – all of the guys that have had to step up."

Urlacher was initially replaced by Hillenmeyer until he was hurt in Week 3, which forced Roach into the middle. Roach fist filled in for Tinoisamoa at strong-side linebacker, starting on the first series of the first game. When he slid over to the middle, Williams moved in on the strong side.

That should make the defense even stronger when it gets back close to full strength. Even though this year's bye is early, it should allow Tinoisamoa and Hillenmeyer to return at full speed for the Falcons game on Oct. 18, so it comes at an advantageous time.
