NFC North at (near) night(fall)

Some prominent NFC North players have missed a significant portion of Week 2 practices. The most recent addition is Minnesota Vikings middle linebacker E.J. Henderson. The details:

Chicago Bears: Linebacker Brian Urlacher returned to practice after rejoining the team following his mother's death. But the Bears were without safety Chris Harris (hamstring) and receiver Roy Williams (groin) for the second consecutive day. Meanwhile, tailback Marion Barber (calf) returned to the sideline after practicing Wednesday.

Detroit Lions: Receiver Calvin Johnson (ankle) and safety Louis Delmas (hip) again sat out practice. Johnson has said he will play Sunday against the Kansas City Chiefs, but Delmas' status is less clear. He would probably be replaced by Erik Coleman if he can't play against the Chiefs.

Green Bay Packers: Cornerback Tramon Williams (shoulder) again missed practice, but coach Mike McCarthy said Wednesday he would be comfortable playing Williams on Sunday against the Carolina Panthers even if he missed Thursday's workout. The key will be whether Williams gets on the practice field for at least a portion of the work Friday.

Minnesota Vikings: Henderson woke up with knee swelling and didn't practice Thursday while undergoing tests. Henderson's primary backup, Jasper Brinkley, is out for the season because of hip surgery. So during practice Thursday, waiver claim Xavier Adibi worked at middle linebacker. Weakside linebacker Erin Henderson also took some repetitions.
