"He went down to make a tackle, got his neck jammed into his back and had lower back spasms or pain," Sherman said. "He'll be out a day or two, but I think he'll be okay. At least, the doctor's reports were he'll be okay."
The situation may have the Packers wishing that backup safety Matt Bowen could be in two places at once. Bowen has been spending the bulk of his time at strong safety due to injuries to Antuan Edwards and Marques Anderson. Meanwhile, he is listed as the primary backup to Sharper at free safety.
While Sherman's preliminary timetable for Sharper's return would have the free safety back in time for the preseason home opener against Cleveland Monday night, it is not yet known if Sharper will be given the green light to play in that game.
