"It's getting better," Urlacher said Sunday on his weekly Fox Chicago segment. "I'm not sure what I'll be this week or next week, but it feels better than it has been, so that's good. I have no idea (if he'll play against Arizona). I'll see how this week goes and either I will or I won't.
"I haven't even tried to run yet. I've done some swimming, like always, some swimming in the pool. And just trying to keep it from hurting."
Urlacher hurt the hamstring late in the Dec. 2 loss to the Seattle Seahawks.
