Footballoutsiders.com is reporting that Bears linebacker Brian Urlacher will miss 4-6 weeks after undergoing surgery on his dislocated wrist.

From Rotoworld.com:

The site doesn’t normally break news, but injury expert Will Carroll has connections with team medical staffs. Veteran Hunter Hillenmeyer will fill in for Urlacher, which will hurt the Bears run defense. We’d still sit Willie Parker against Chicago in Week 2.

Things go from bad to worse for the Bears. Urlacher was reportedly in the best shape of his life this summer after struggling with neck and back issues last year. So it’s unfortunate that an injury like this will cause him to miss games.

The good news is that the Chicago’s front four generated great pressure last night on Packers quarterback Aaron Rodgers so if they can continue that trend, it at least softens the blow of losing Urlacher.

Update: The Chicago Tribune is now reporting that Urlacher is likely done for the season after having a dislocated bone put back into his wrist. This is obviously a huge blow to the Bears, who will either move Lance Briggs to middle linebacker or start Hunter Hillenmeyer in Urlacher’s place.
