Broncos running back Willis McGahee has undergone a career renaissance in Denver, averaging a 4.9 yards per carry in 2011 -- comparable to the Bears' running back Matt Forte. McGahee has struggled with knee injuries this season, but has missed only one game so far, a Week 8 loss to the Detroit Lions.
Though much credit is due to Tim Tebow, the Broncos offense truly revolves around McGahee's consistent production at the tailback position. Alongside him on the injury report is veteran wideout Eddie Royal, who has struggled to be productive even when healthy in 2011.
The other two significant injuries on the Broncos' roster include rookie linebacker Von Miller -- who sports an impressive 10.5 sacks -- and starting left tackle Ryan Clady. In Week 13 against the Kansas City Chiefs, the Bears allowed a whopping 9 sacks to a defense that had up to that point been sack-impaired. If Miller cannot play against the Bears in Week 14, the Chicago offensive line has a decent chance at keeping Caleb Hanie upright for at least half the game.
