The Cardinals have lost linebacker Karlos Dansby and safety Aaron Francisco for the next 3-4 weeks as they both have knee problems.  Dansby will be hard to replace as he is the team’s leading tackler with 44.  He also has 2 sacks and a fumble recovery.  Francisco will be missed mostly on special teams as he has made 11 tackles so far this season.  The Cardinals can’t afford any more injury problems on defense because they don’t have much depth there.
