NFC North at night

Checking in on Thursday's news bits:

Chicago Bears: Cornerback D.J. Moore missed practice after suffering an ankle injury Wednesday. If he can't play, the Bears could look at Corey Graham or Zack Bowman in the nickel Sunday against the San Diego Chargers. Defensive end Julius Peppers (knee) practiced Thursday.

Detroit Lions: Safety Amari Spievey (toe) returned to practice Thursday as a limited participant. Running back Jahvid Best (concussion) watched practice but did not participate. Punter Ryan Donahue (quadriceps) didn't practice. Neither did defensive ends Willie Young (ankle) and Lawrence Jackson (thigh). Quarterback Matthew Stafford (finger) had full participation in practice.

Green Bay Packers: Linebacker Desmond Bishop and guard T.J. Lang, both of whom missed practice Wednesday for personal reasons, returned Thursday. Running back Ryan Grant (knee) also returned to practice and had full participation.

Minnesota Vikings: Defensive end Jared Allen has been filling in as the team's long snapper in practice because of Cullen Loeffler's shoulder injury. But coach Leslie Frazier told reporters there is "no chance" he would use Allen in that role Sunday against the Oakland Raiders. If Loeffler isn't ready, the Vikings will sign an emergency snapper. Safety Husain Abdullah (concussion) continues to be sidelined and doesn't appear likely to play Sunday. Tyrell Johnson and Jamarca Sanford would be the starters.
