Earlier this season, the Packers set a franchise record with 42 straight games with a sack. Against Denver two weeks ago, the Packers had no sacks and just three quarterback hits on veteran Peyton Manning. Manning had the Packers reeling with his mix of handoffs and play-action passes, Packers defensive coordinator Dom Capers said. At 1-7, Detroit is in disarray after replacing its offensive coordinator and letting go of two offensive line coaches earlier this month. The Packers' pass rush also could get a boost from their secondary, where top cornerback Sam Shields looks as if he is poised to return after missing all or most of the past two games with a shoulder injury. Cornerback Casey Hayward (concussion) was limited for Thursday's long practice after missing Wednesday, while Quinten Rollins (neck) was a full participant for a second straight day. Having all three cornerbacks available would help the Packers cover Lions star receiver Calvin Johnson.
