The Packers return to the practice field Wednesday in advance of Sunday's 184th regular season meeting with the Chicago Bears.  If Green Bay wins at Soldier Field, they'll clinch a second straight NFC North Division title.  The big storyline heading into the game is whether Clay Matthews and Charles Woodson will return to the field.  Both are expected to practice at least on a limited basis.  Jordy Nelson and T.J. Lang are also recovering from injuries that forced them out of last Sunday night's victory over Detroit.   On the defensive line, the Packers are still concerned about C.J. Wilson's knee injury and a bum shoulder of Mike Neal.   Green Bay dressed only four healthy linemen against the Lions and to protect themselves, the Packers have promoted defensive tackle Jordan Miller from the practice squad to the active roster.  Miller is a 6-1, 317 pound tackle from Southern University.  He spent 15 games on the Chicago Bears practice squad in 2011.  To make room for Miller on the roster, Green Bay waived linebacker Vic So'oto.  As for the Bears, they've lost their placekicker for the rest of the season as Robbie Gould was placed on injured reserve Tuesday with a calf injury.  Chicago signed veteran Olindo Mare to take his place.
