Bears linebacker Brian Urlacher wants changes made to the playing surface at Solider Field. "I don't understand why we don't have FieldTurf yet," Urlacher said. "We're a fast team, we play fast on FieldTurf. The injury issues aren't as bad as they used to be, they've gone down a lot in the last few years with the way they've made the turf and stuff. I don't understand it. Use our speed. We can run, let us go out there and run." Citing safety concerns about the Soldier Field playing surface, the Bears canceled Friday's Family Fest practice.
