The Chicago Tribune reports Brian Urlacher is expected to miss the next three games with a Grade 2 hamstring strain. Urlacher said he heard a "pop" while chasing Russell Wilson late in last week's game. He could end up missing the remainder of the regular season, with the goal to return for the playoffs. Despite losing a step to knee woes, Urlacher has been the Bears leading tackler (88) while producing three forced fumbles and two fumble recoveries. Nick Roach is expected to move to the middle with Geno Hayes entering the lineup on the strong side.
