Jerick McKinnon popped up on the injury report yesterday with a lower back injury, something that has been nagging the rookie running back for a little while now. But both head coach Mike Zimmer and McKinnon said that it won't affect McKinnon's status or his role for Sunday's game in Chicago.

"It's just something that I've been dealing with," said McKinnon, who has been getting treatment for the injury. "I was feeling good today, moving around pretty good. So I'm just ready for Sunday."

McKinnon said he suffered the injury "in the facility just doing some work." He wouldn't elaborate.

McKinnon was officially listed as probable on the injury report, and the injury shouldn't prevent McKinnon, the NFL's leading rusher among rookies with 446 yards, from getting the majority of the carries against the Bears, though Matt Asiata will remain involved, especially if near the goal line.

"I'd be pretty comfortable with whatever workload they place on me," McKinnon said.

Zimmer also said that he expects Kyle Rudolph to suit up Sunday, though it is unclear if the tight end in his return will re-assume the large workload he had before sports hernia surgery in Week 3.

Rudolph was listed as probable. His backup, Chase Ford, is also probable despite a foot injury.

Offensive tackle Mike Harris (ankle) and rookie defensive end Scott Crichton (hip) are questionable. Harris practiced Wednesday and Thursday but sat out today with what looks to be a new injury.

Tight end Martellus Bennett, cornerback Tim Jennings and wide-out Brandon Marshall were among the five players the Bears listed as probable. Offensive tackle Jordan Mills is doubtful. Defensive end Trevor Scott, offensive lineman Eben Britton and linebacker Darryl Sharpton were ruled out.
