Let's get inside the Friday injury report in the NFC North:
Chicago Bears: Defensive tackle Henry Melton (chest) returned to practice Friday but is doubtful for Sunday's game at the Arizona Cardinals. Linebacker Brian Urlacher (hamstring) has been ruled out. There is some optimism that receiver Earl Bennett (concussion) and cornerback Tim Jennings (shoulder) will play. They are both listed as questionable. Linebacker Geno Hayes (knee) and defensive end Shea McClellin (knee) are probable.
Detroit Lions: Tight end Brandon Pettigrew (ankle) wasn't able to practice all week and is doubtful for Saturday night's game against the Atlanta Falcons. Safety Louis Delmas (knee) is questionable but expected to play. All other players on the roster should be available.
Green Bay Packers: We've already noted that center Jeff Saturday (neck/shoulder) has been replaced by Evan Dietrich-Smith. Running back Alex Green (concussion) is questionable for Sunday's game against the Tennessee Titans. If he can't play, DuJuan Harris and Ryan Grant will carry the load. Guard T.J. Lang (concussion) has been cleared to play. Defensive back Charles Woodson (collarbone) was ruled out, as were receiver Jordy Nelson (hamstring), defensive end C.J. Wilson (knee) and running back James Starks (knee).
Minnesota Vikings: Defensive end Brian Robison (shoulder) participated in a portion of practice Friday and is questionable for Sunday's game at the Houston Texans. All other players on the roster should be available, and it sounds like the Vikings will active cornerback Chris Cook (wrist) from injured reserve as well.
