Receiver Jordy Nelson, who limped off the field late in Saturday's playoff game against Minnesota, did not practice today, when the Packers began preparations for Saturday's divisional playoff game at San Francisco.
Nelson had a knee injury going into the game.
Others who didn't attend practice today were safety Jerron McMillian and defensive end Jerel Worthy.
Tight end Jermichael Finley, who sustained a hamstring against the Vikings, returned to practice. So did receiver Jarrett Boykin, who missed the game because of an ankle injury.
The Packers don't have to submit an official injury report today, so it's likely there will be no official word on any injuries until tomorrow.
