NFC North Friday injury report

Let's finally get inside the Friday injury report:

Detroit Lions: Safety Louis Delmas (knee) did not practice Friday, but it sounds as if it was for precautionary reasons. "We had planned to ease him back at the end of the week," coach Jim Schwartz said. "He's doing well. He's not having any setbacks and I'd like to keep it that way." Delmas is officially listed as questionable but he appears on track to play Sunday at the Philadelphia Eagles. The only player who isn't expected to be available Sunday is defensive tackle Corey Williams (knee).

Green Bay Packers: We reviewed the Packers' situation earlier Friday, available through this link. In short, they won't have receiver Greg Jennings (groin) Sunday night against the Houston Texans and they might not have nose tackle B.J. Raji (ankle), either. Tight ends Jermichael Finley (shoulder) and D.J. Williams (hamstring) are both questionable for the game and might be game-time decisions.

Minnesota Vikings: Safety Jerome Simpson (back/foot) practiced Friday but is questionable for Sunday's game at the Washington Redskins. Coach Leslie Frazier said Simpson is "better [but] not quite there." Defensive lineman Everson Griffen re-joined the team two days after his mother died unexpectedly in Minnesota. He is expected to travel to Washington, D.C., with the team and play Sunday. Linebacker Marvin Mitchell (calf) is doubtful and unlikely to play. Meanwhile, Redskins quarterback Robert Griffin III (head) is expected to start despite being listed as questionable.
