NFC North injury roundup

Posted by ESPN.com's Kevin Seifert
We have a lot of significant injury information flowing Wednesday afternoon here in the Black and Blue. Let's take a team-by-team look:

Chicago: The Bears have listed receiver Marty Booker (cracked rib) as doubtful for Thursday night's game against New Orleans. Brad Biggs of the Chicago Sun-Times reports Booker almost certainly won't play. For a while now, the Bears have been relying on Devin Hester, Rashied Davis and Brandon Lloyd as their top three wide receivers.

Detroit: Quarterback Daunte Culpepper (shoulder) was on the Lions practice field for warm-ups, but that's about it. Coach Rod Marinelli told reporters that Culpepper is "more doubtful than probable" for Sunday's game at Indianapolis. Former starter Dan Orlovsky practiced Wednesday but is still recovering from a hand injury, making it increasingly likely that Drew Stanton will get his first NFL start. The Lions' other option, barring a quick turnaround from Culpepper, would be Drew Henson.

Green Bay: The Packers have ruled out safety Atari Bigby (ankle) for Sunday's game at Jacksonville. That means cornerback Charles Woodson will make his third consecutive start at the position. Linebacker Brandon Chillar (groin) was limited and could give way to Desmond Bishop for the second consecutive game.

Minnesota: Quarterback Gus Frerotte said late Wednesday afternoon that he heard something "pop" when he injured his lower back Sunday at Detroit. Asked if he has a fractured bone, as has been reported, Frerotte said: "No." Frerotte said he hopes to return to practice at some point this week but that he is uncertain when or if it will happen. ... Frerotte and defensive end Jared Allen (knee) were two of five players who sat out practice. Coach Brad Childress said Allen is expected to play Sunday at Arizona.
