NFC North Friday injury report

Getting inside the Friday injury report:

Chicago Bears: Linebacker Nick Roach (hamstring) was limited in practice Thursday and Friday and is listed as questionable. The guess is that he won't play Sunday at the Dallas Cowboys. All other Bears players are expected to be available.

Detroit Lions: Defensive end Cliff Avril (knee/finger) and quarterback Matthew Stafford (right shoulder) have been ruled out for Sunday's home opener against the Philadelphia Eagles. Linebacker DeAndre Levy (groin) and safety Louis Delmas (groin/biceps/leg) are listed as questionable. The guess is Delmas has a better chance of playing than Levy. The Lions haven't given up on the possibility of Levy playing after he participated in two days of practice this week, but he might be set up to make his return in Week 3.

Green Bay Packers: Left guard Daryn Colledge (illness) and fullback Korey Hall (hip) were added to the injury report and listed as questionable, but it seems likely that Colledge will play Sunday against the Buffalo Bills. If he can't, rookie Bryan Bulaga would get his first NFL start. Defensive end Mike Neal (side/rib) and cornerback Brandon Underwood (shoulder) are questionable but might be a week away from returning. All other players, including cornerback Charles Woodson (toe), should be available.

Minnesota Vikings: Receiver Percy Harvin (hip) returned to practice Friday and is expected to play Sunday against the Miami Dolphins even though he is listed as questionable. Cornerbacks Cedric Griffin (knee) and Chris Cook (knee) are also questionable, but much less likely to play than Harvin. Running back Toby Gerhart (knee) is probable and will be available to play.
