NFC North at night

Catching up on Thursday’s news bits around the NFC North, including what is expected to be a one-day practice absence for a part-time receiver in Minnesota:

Chicago Bears: Receiver Roy Williams (groin) fully participated in practice, a good sign for his availability for Sunday’s game against the Green Bay Packers. Safety Major Wright (head/neck) did not practice, and it’s possible the Bears could use a mix-and-match approach Sunday with Chris Harris (hamstring), Brandon Meriweather, Craig Steltz and possibly Chris Conte. Guard Lance Louis (ankle) and running back Marion Barber (calf) were limited. Harris said he is "optimistic" he will be able to play.

Detroit Lions: Most players who sat out Wednesday’s practice returned Thursday. Tight end Brandon Pettigrew (shoulder) was the most notable exception. Pettigrew missed his second consecutive day.

Green Bay Packers: Cornerback Tramon Williams (shoulder) participated in his second consecutive day of practice, this time in full pads, and the Packers appear optimistic that he can play Sunday. Linebacker Clay Matthews (quadriceps) and cornerback Charles Woodson (foot) both sat out for a second consecutive day, but it’s expected that both will be available for the Bears game.

Minnesota Vikings: Receiver Percy Harvin missed practice because of an illness, but coach Leslie Frazier said Harvin does not have a migraine and is expected to be at practice Friday. Defensive end Jared Allen (shoulder) was a full participant Thursday. Cornerback Chris Cook (groin) made it through another practice as well.
