Urlacher has not played since Dec. 2 and the Bears have allowed 21 points or more in each game throughout his absence. The Bears have held opponents under that mark seven times this season when Urlacher has been on the field.
It's also looking like the Bears will be without another impact defender in the form of DT Henry Melton (chest). Melton was a limited participant in all three practices this week but was still listed as doubtful, which is an ominous sign for someone who already sat out last week's game.
As for the rest of the injury report, WR Earl Bennett (concussion), LB Blake Costanzo (calf), CB Tim Jennings (shoulder) and T Jonathan Scott (hamstring) are all questionable. LB Geno Hayes (knee), WR Brandon Marshall (hamstring) and DE Shea McClellin should be ready to roll after being assigned probable tags.
