Brian Urlacher is likely to miss the Bears' next three games, and possibly all four Bears regular-season games remaining, due to a grade 2 right hamstring strain suffered in overtime of the Bears' awful 23-17 loss vs. the Seahawks on Sunday:

The Bears have to brace themselves for the possibility of Brian Urlacher missing at least the rest of the regular season.  
Multiple sources told the Tribune that Urlacher won't play for the next three games at a minimum after suffering a Grade 2 right hamstring strain during Sunday's 23-17 overtime loss to the Seahawks. An MRI confirmed the severity of Urlacher's injury.
The Bears (8-4) have four more regular-season games, starting with Sunday's division matchup against the Vikings in Minnesota. Urlacher hopes to recover in time for the playoffs, which start with wild-card weekend games Jan. 5-6.

Nick Roach will take over at middle linebacker for Urlacher, while first-year Bears linebacker Geno Hayes will move into Roach's traditional strong-side linebacker position.

The Bears also signed middle linebacker Dom DeCicco to a two-year deal on Tuesday, and he'll likely be Roach's primary backup at middle linebacker. ChicagoBears.Com has more on DeCicco:

DeCicco appeared in all 16 games for the Bears last season as a rookie after arriving as an undrafted free agent from Pittsburgh, finishing second on the team with 17 special teams tackles. The 6-4, 230-pounder was waived by the Bears on Aug. 29.
Linebacker Patrick Trahan was waived (again) to make room for DeCicco on the 53-man roster.

Urlacher's loss will be felt more in terms of things like leadership, play recognition, and essentially "quarterbacking" the defense, than it will be felt from a a skills standpoint. Jeff Dickerson summed up very well what will especially be missed about the future Hall of Famer:
Urlacher's knee issues over the last year have clearly taken away a ton of his athleticism, and frankly he's looked very slow at times this year. The Bears may even look a bit faster on the field with Roach moving to the middle and Hayes moving into the lineup at the strong-side spot. But, there's no doubt that Urlacher's smarts and irreplaceable ability to captain the defense will be very missed.

While odds are the Bears still make the playoffs, it's certainly far from a given, especially with a tough remaining schedule and many key players dealing with injuries. And even if the Bears do make the playoffs, it's possible that Urlacher's hamstring is not healthy enough to play in the first game.

So, is it possible we've seen the last of No. 54 in a Bears uniform? Urlacher was asked about that on Tuesday night by Fox Chicago's Lou Canellis

Whatever the case, general manager Phil Emery needs to try to find Urlacher's potential successor in the offseason.
