"Brian is family,'' Smith said. "We see it like a family member passed away. So of course we're going to be there. The Bears will be represented well. We want to be there to show our support and help Brian as much as we can through a tough time.''
Urlacher returned to practice Thursday and is expected to start Sunday against the New Orleans Saints.
