"I guess it all depends on how he responds this week," said Sherman of Sharper, who was not fluid while trying to play while wearing a knee brace.
Meanwhile, the Packers emerged from the 34-31 victory against Minnesota in relatively good health.
The position to watch is running back, where starter Ahman Green sat out the final four-plus minutes of the first half after taking a heel to his left kneecap and backup Najeh Davenport injured his left hamstring.
Sherman said Green will be rested at the onset of the practice week. That isn't unusual since Green has been troubled with a nagging Achilles' injury but has excelled while getting Wednesdays and Thursdays off.
Davenport underwent a magnetic-resonance-imaging exam Monday. He missed three games after injuring his right hamstring while returning a kickoff in the opener at Carolina.
Also undergoing an MRI was backup tight end David Martin. Martin injured his left knee, which has been an ongoing problem requiring periodic draining since.
The results of the MRIs were not made available.
Wide receiver Robert Ferguson suffered a sprained shoulder in the first half but returned to generate a couple of long kickoff returns.
Starting weak-side linebacker Na'il Diggs missed the Vikings' final series of the game with a bruised calf.
