NFC North Friday injury report

Getting inside the Friday injury report, which is really a Thursday report for one team because of Monday Night Football:

Chicago Bears: We already noted that running back Matt Forte (ankle) has been ruled out for Sunday's game against the St. Louis Rams. Michael Bush will start in Forte's place, and all other players are expected to be available.

Detroit Lions: Tight end Tony Scheffler didn't practice all week because of a calf injury and isn't expected to play Sunday against the Tennessee Titans. He is officially listed as doubtful, as is safety Louis Delmas (knee) and linebacker Travis Lewis (quad). Meanwhile, cornerback Jacob Lacey (toe) turned up on the injury report and is questionable for the game. He was limited Friday, but starting cornerbacks Chris Houston (ankle) and Bill Bentley (concussion) are listed as probable for the game.

Green Bay Packers: Receiver Greg Jennings participated in a portion of Friday's practice despite a setback with his groin injury this week. He told reporters that he thinks he'll be able to play Monday night against the Seattle Seahawks, but the Packers don't have to reveal their injury designations until Saturday.

Minnesota Vikings: Linebacker Erin Henderson (concussion) won't play Sunday against the San Francisco 49ers. He'll be replaced in the base defense by Marvin Mitchell and in the nickel by Jasper Brinkley. Defensive end D'Aundre Reed (calf) is also out, but all other players should be available.
