GREEN BAY, Wis. -- Receiver Jordy Nelson won't practice when the Green Bay Packers begin training camp on Tuesday.

Nelson was one of six Packers placed on the physically unable to perform list on Monday. Nelson is coming back from a torn right ACL injury that kept him out for the 2015 season.

The Packers have said that they might be cautious with Nelson as he comes back from injury. The Packers also have five preseason games this year since they play in the Hall of Fame game on Aug. 7.
