NFC North Wednesday practice report

Let's take a quick roundup of a newsy Wednesday in the NFC North:

Chicago Bears: The Bears didn't practice so there was no injury report. We've already noted that coach Lovie Smith said quarterback Jay Cutler (concussion) is improving. According to ESPN's Adam Schefter, San Francisco 49ers quarterback Alex Smith has passed his concussion tests this week and is on track to play against the Bears on Monday night. Meanwhile, place-kicker Robbie Gould issued an apology for the comments he made Monday night about the playing surface at Soldier Field. Gould said he spoke "prior to having a full understanding" of the issues involved. It should be noted, however, that the Chicago Tribune reported Soldier Field will be re-sodded this week.

Detroit Lions: Missing practice Wednesday were safeties Louis Delmas (knee), Erik Coleman (eye) and Amari Spievey (concussion); along with defensive end Cliff Avril (back/concussion), cornerback Chris Houston (ankle), defensive tackle Corey Williams (knee) and receiver Calvin Johnson (knee). Meanwhile, the Elias Sports Bureau awarded defensive tackle Ndamukong Suh a sack on a play when he touched Minnesota Vikings quarterback Christian Ponder after he tripped over an offensive lineman's foot. That adds to what coach Jim Schwartz said was one of Suh's best-ever games.

Green Bay Packers: The Packers ruled out linebacker Clay Matthews (hamstring) from Sunday's game against the Lions. The same goes for receiver Greg Jennings (abdomen) and cornerback Charles Woodson (collarbone). Defensive end Mike Neal (ankle) also did not practice. Fullback John Kuhn (hamstring) was limited.
