Van Ness (concussion) was limited at the Packers' practice Wednesday.
Van Ness recorded four solo tackles, including 1.0 sacks, in the team's 39-22 loss to the Vikings in Week 1, but he appears to have suffered a concussion at some point in the contest. The 25-year-old's ability to practice in any capacity is a positive sign, but he will have to clear concussion protocol in order to play Sunday on the road versus the Jets.
