"He's getting better," coach Lovie Smith said.
Cutler is officially listed as questionable on the Bears' injury report, but only because he needs to pass the final step in the NFL's concussion protocol. Cutler practiced again on Friday after being limited on Thursday.
"He was able to do more today, than he did yesterday," Smith said afterward. "He's looking good. ... It's looking better. The last phase of his evaluation will be tomorrow and then we'll be able to let you know more from there."
Cutler suffered his concussion Nov. 11 against the Houston Texans when he was hit in the head by linebacker Tim Dobbins, who was fined $30,000 for it.
Cutler, who has a history of concussions, sat out every practice last week and also meetings as he recovered. He said this week that this concussion didn't feel any different.
"No, I haven't experienced anything out of the normal of the other concussions I've had," Cutler said.
Cutler said his concussion history won't change the way he plays, but he's considered the long-term effects of concussions, especially with a son now.
"There's a lot of awareness out there," Cutler said. "But you trust the doctors and our training staff that we're going to make the right decision for my health not only in the near future, but lifetime going forward."
In other injury news, defensive end Shea McClellin (concussion) has been cleared and fully participated on Friday. He's listed as probable.

As for the Vikings, standout receiver Percy Harvin (ankle) is doubtful for Sunday.
