A few personnel updates

Posted by ESPN.com's Kevin Seifert
This week is unusually newsy on the NFC North personnel front. Two of the division's starting quarterbacks are battling significant injuries, as is the NFL's reigning sack champion. Let's take a look at each situation:

  • Chicago quarterback Kyle Orton (ankle) sat out practice for the second consecutive day. The Bears will have to designate his status on Friday's injury report, and it seems that even "questionable" will be a stretch. It remains likely that Rex Grossman will start Sunday against Tennessee with rookie Caleb Hanie as the backup.

  • Detroit quarterback Dan Orlovsky had his injured thumb examined by a specialist in New York on Thursday, again leaving newcomer Daunte Culpepper to share snaps with Drew Stanton in practice. Culpepper remains the likely starter Sunday against Jacksonville, but coach Rod Marinelli wouldn't commit to that scenario Thursday. Marinelli did say: "The learning curve is gigantic each day for a veteran guy. They can see it fast."

  • Minnesota defensive end Jared Allen missed practice for the second consecutive day. That's not a deal-breaker for a veteran like Allen, but his third-degree shoulder sprain -- yes, it appears he was telling the truth Wednesday -- makes it pretty unlikely he will play Sunday against Green Bay. Second-year player Brian Robison is the likeliest replacement.
