Let's get inside Friday's NFC North injury report:
Chicago Bears: As expected, the Bears ruled out linebacker Brian Urlacher (hamstring), cornerback Tim Jennings (shoulder) and receiver Earl Bennett (concussion) from Sunday's game against the Green Bay Packers. The Bears could also be short along the defensive line because Henry Melton (chest) and Shea McClellin (knee) are both listed as doubtful while Matt Toeaina (knee) is questionable. Neither Melton nor McClellin practiced this week. Meanwhile, linebacker Geno Hayes (knee) and running back Michael Bush (ribs) are questionable. The Bears would probably use Blake Costanzo at strong-side linebacker if Hayes can't play.
Detroit Lions: Two key players appear unlikely to be available for Sunday's game against the Arizona Cardinals. Tight end Brandon Pettigrew (ankle) and defensive lineman Nick Fairley (shoulder) both missed practice all week and are listed as doubtful. The Lions could promote tight end Shaun Chapas from the practice squad to provide depth Sunday. Meanwhile, safety Louis Delmas (knee) is questionable for the game.
Green Bay Packers: The Packers ruled out four players from Sunday's game: Receiver Jordy Nelson (hamstring), running back James Starks (knee), defensive end C.J. Wilson (knee) and defensive back Charles Woodson (collarbone). Right guard Josh Sitton was added to the injury report because of a hip injury that flared up Thursday and prevented him from practicing Friday. He is listed as questionable, but the Packers are holding out hope he will play Sunday. Fellow guard T.J. Lang (ankle) is listed as probable for the game.
Minnesota Vikings: All players are at least probable for Sunday's game against the St. Louis Rams except for cornerback Antoine Winfield, who sat out practice all week because of a knee injury. Coach Leslie Frazier, however, told reporters he thought Winfield would be ready to play.
