NFC North at night

Chicago Bears: Receiver Devin Hester (calf) missed his second consecutive day of practice. Hunter Hillenmeyer (groin) was back in practice after sitting out Wednesday. Here is Jeff Dickerson’s Bears blog over on ESPN Chicago for more details on the Bears’ day.

Detroit Lions: Tight end Casey Fitzsimmons (concussion) sat out practice again and isn’t likely to play Sunday at Baltimore.

Green Bay Packers: Linebacker Nick Barnett (knee) returned to practice on a limited basis. Nose tackle Ryan Pickett (hamstring) missed his second consecutive day. There are still legitimate questions about whether any of the Packers' starting defensive linemen -- Pickett, along with ends Cullen Jenkins (hamstring) and Johnny Jolly (knee) -- will be ready for Sunday's game at Chicago.

Minnesota Vikings: Receiver Percy Harvin did not practice because of migraine headaches, according to the Star Tribune. Harvin dealt with a similar issue earlier this season but recovered in time to play Sept. 27 against San Francisco. Safety Tyrell Johnson (concussion) did not practice. Tailback Adrian Peterson (foot/ankle) and offensive lineman Phil Loadholt (shoulder) returned to practice on a limited basis.
