Chicago Bears linebacker Brian Urlacher said that his conditioning continues to improve and he felt more active in Sunday's 23-6 win over the St. Louis Rams.

Urlacher missed most of training camp and all of the offseason activities as he recovered from a knee injury he suffered in last season's finale. He underwent at least one surgical procedure on the knee.

"I felt like I was involved in more plays," Urlacher said on Fox's postgame show in Chicago.

Urlacher was credited with four tackles against the Rams, including three solos. He also had a tackle for a loss and broke up a pass.

"I think I'll get better and better every week, my legs will get underneath me and I'll get in better shape," he said. "(The knee) is good. If it wasn't good, I wouldn't be playing. So I feel good about it.

"(The conditioning) is getting better. The more I play, the better I'll get. It feels better and better every week. I feel pretty good conditioning wise."
