Let's catch up on some injury developments around the NFC North:
The Chicago Bears practiced without linebacker Lance Briggs (ankle), left tackle Chris Williams (hamstring) and safety Major Wright (hamstring). Wright is expected to miss up to a month's worth of games. If Williams can't play Monday night against the Green Bay Packers, the Bears will start Frank Omiyale at left tackle and Kevin Shaffer at right tackle. Briggs is expected to play.
The Detroit Lions, meanwhile, are expected to get middle linebacker DeAndre Levy back for Sunday's game against the Minnesota Vikings. Levy (groin) has made it through two days of practice without incident. Guard Stephen Peterman (foot), receiver Nate Burleson (ankle) and linebacker Zack Follett (concussion) sat out practice.
In Green Bay, left tackle Chad Clifton (knee) participated in a limited portion of practice. Coach Mike McCarthy said the team won't announce whether Clifton or rookie Bryan Bulaga will start Monday night, but said: "Chad Clifton is the starting tackle. If he is medically unable to go, then we'll see what happens."
Minnesota Vikings receiver Percy Harvin returned to practice one day after suffering a migraine episode. Harvin has typically needed a week or more to recover, but he said: "I went home, got a good night's rest and I woke up energized and ready to work today." Meanwhile, rookie cornerback Chris Cook (knee) participated fully for the second consecutive practice and should be available to make his NFL debut Sunday.
