NFC North Wednesday practice report

Let's round up a busy day of roster and injury news in the NFC North:

Detroit Lions: Tight end Brandon Pettigrew (knee) returned to practice after sitting out Tuesday. Receiver Titus Young (knee) didn't practice. Neither did defensive tackle Corey Williams, who is sidelined after knee surgery. Safety Louis Delmas again practiced, but was officially listed as limited. Coach Jim Schwartz acknowledged that Young's knee injury has impacted his season in terms of the value of missed practice time.

Green Bay Packers: Tailback Cedric Benson, who will miss at least eight weeks because of a foot sprain, was placed on the new form of injured reserve that would allow him to return at the end of the season if he has recovered. The Packers will revisit the issue in December. Meanwhile, tight end Jermichael Finley (shoulder), nose tackle B.J. Raji (ankle) and receiver Greg Jennings (groin) all sat out practice. Finley continues to insist he can play Sunday night against the Houston Texans, but that won't be his decision.

Minnesota Vikings: No serious injuries were found with receiver Jerome Simpson's back, and while he did not practice Wednesday, the Vikings don't think he has a long-term injury. Running back Adrian Peterson (ankle) did not practice but is not believed to be in jeopardy for Sunday's game at the Washington Redskins. Defensive tackle Kevin Williams (illness) also sat out practice. Meanwhile, Redskins quarterback Robert Griffin III (concussion) practiced on a limited basis. At this point, he appears on track to play Sunday.
