08:00 AM ET 12.05 | A Brian Urlacher injury has again become a significant issue in Chicago, this one with long-lasting implications. The dark cloud settling over this Bears season grew even more ominous Tuesday with news that [Urlacher] likely will miss three of the team's final four games with a Grade 2 hamstring strain. It's possible Urlacher could miss the rest of the season with an eye toward a return for the playoffs. ... This injury to this player feels different. So different that you can't help but wonder if this is the end of an era -- if it is the end of Urlacher with the Bears. And if the team does miss the playoffs, where does that leave coach Lovie Smith? The suspicion is that Smith's future isn't tied to Urlacher's, but that Urlacher's future certainly is tied to Smith's.
