Cornerback Tim Jennings officially was ruled out of Sunday's game with a shoulder injury, but wide receivers Alshon Jeffery (knee) and Devin Hester (concussion) are expected to play against the Minnesota Vikings at the Metrodome.
Middle linebacker Brian Urlacher (hamstring) and wide receiver Earl Bennett (concussion) previously were ruled out for Sunday's game. That leaves the Bears without four starters Sunday. Guard Lance Louis (knee) suffered a season-ending knee injury against the Vikings two weeks ago.
Kelvin Hayden will replace Jennings at cornerback. Nick Roach moves from the strong side to the middle to replace Urlacher. Reserve linebacker Geno Hayes will play the strong side for Roach.
Running back Michael Bush (ribs), defensive tackle Stephen Paea (foot) and guard Chris Spencer (knee) all practiced on a limited basis and are expected to play Sunday.
For the Vikings, wide receiver Percy Harvin (ankle) is out. The only other players on their injury report, including defensive end Jared Allen (shoulder/back) are probable.
Despite being without four starters, coach Lovie Smith was upbeat about his team's health going into the final four weeks of the regular season.
''We have a few injuries, but for the most part we have our team ready to go,'' he said. ''The guys are excited. You can't ask for anything more.''
