49ers running back Christian McCaffrey will be on the field to start the practice week, but he won't take 100 percent of his usual snaps. Head coach Kyle Shanahan said in his Thursday press conference that McCaffrey will be limited in the session with the same calf issue that sidelined the running back during training camp.
