The Broncos' defensive line appears to be thinning as they prepare to face the Bears in Chicago.
Defensive ends Antonio Smith (hip) and Vance Walker (shoulder) were again absent from practice Friday, third third consecutive workout they've missed this week because of injuries.
"One good thing about that position is it's where we are deep," coach Gary Kubiak said Thursday. "(Darius) Kilgo hasn't been playing. You would like to have both of those guys, but I think Kilgo was playing well for us early in the season. If he has to go — I think one of these guys could be there for us on game day.
