Urlacher initially feared he had suffered an ACL injury.
"I was thinking the worse possible scenario,'' he said. "I felt something pop in my knee when I did that little move on the ground. I never hurt my knee like that before so I didn't know what to think. (Trainer) Tim Bream was out there in two seconds. They tested my ACL then and said it was fine.
"They were right on. They said MCL/PCL was what they thought, and of course they were right.''
