Deactivations from around the NFC North

CHICAGO -- There were no huge surprises among the game-day deactivations just announced in the Soldier Field press box.

Minnesota Vikings receiver Percy Harvin (migraines) will play and is in the starting lineup. Cornerback Asher Allen (concussion) is inactive and will be replaced by rookie Chris Cook. Lito Sheppard and Frank Walker will rotate in the nickel. That's a good matchup for the Chicago Bears.

The Bears will be without cornerback Zack Bowman (foot) for another week, but otherwise are at full strength.

In Buffalo, meanwhile, the Detroit Lions announced that left end Cliff Avril won't play against the Bills. Turk McBride will replace him in the starting lineup. Also, Amari Spievey will again replace injured safety C.C. Brown.
