The Packers returned to the practice field this afternoon to begin preparing for their home opener against the Buffalo Bills Sunday at Lambeau Field.   To a man, they expressed disappointment over the season ending injury to running back Ryan Grant but they all realize the show must go on.  Brandon Jackson steps into the starting lineup to make his first start since he was the number one back in three games during his rookie year of 2007.

The rest of the medical report from Wednesday looks like this:  Charles Woodson did not practice to rest a bad toe, Desmond Bishop sat out with a sore hamstring and Mike Neal's abdominal strain also kept him on the sidelines. Four more players were limited in practice, Chad Clifton with a sore knee, Cullen Jenkins with a broken hand, Brandon Underwood with a sore shoulder and Clay Matthews with a sore hamstring.  Derrick Martin was a full participant despite a sore ankle.   As for Matthews, Mike McCarthy said after having not played all pre-season and playing so hard against Philadelphia, the hamstring injury was simply fatigued.  Jenkins said after practice there is considerably less pain in his hand but he'll continue wearing a heavy padded club for a couple of weeks.  Newcomer Dimitri Nance worked out for the first time.  He was signed from the Falcons practice squad to take Grant's roster spot.   Diminutive at 5-8 but with a strong lower body, he's diving into the playbook, particularly on special teams and he hopes to be active on Sunday.
