The Bears already have lost a center and left guard from their starting lineup because of ankle injuries already this season.
Left tackle Jermon Bushrod, limited in practice on Wednesday with a knee issue, was held out of practice altogether on Thursday, with Michael Ola spending some time working at left tackle.
Most of defensive end Jared Allen was back at practice after missing last week and the Green Bay Packers game with what he confirmed was pneumonia.
More than a few Bears fans would have preferred that the 2009 trade that brought Jay Cutler to Chicago never happened. Whether one of those was Cutler himself, hard to say.
Brandon Marshall was damaged when he caught three touchdowns in the win at San Francisco. He was still damaged when he struggled catching one of six balls thrown to him in New York.
