Bears quarterback Jay Cutler took one more significant step toward playing Sunday.
He was limited in practice on Thursday, after missing the last game with a concussion.
"I know you want to know about Jay Cutler, Shea McClellin. Both of them were able to do some things on a limited basis. So it's looking better for them to get them on the football field," Smith said.
Rookie receiver Alshon Jeffery didn't practice and won't play after undergoing a knee scope Wednesday morning.
Tight end Kellen Davis didn't practice because of an ankle injury. Jason Campbell (ribs), Brandon Marshall (shoulder), Stephen Paea (shoulder) and Matt Toeaina (toe) were all limited in practice, along with Cutler.
For the Minnesota Vikings, receiver Percy Harvin didn't practice.
