49ers will err on side of caution with Lattimore, who was encouraged by Gore
Given the severity of his injury, Lattimore has made notable progress. He began sprinting a few weeks ago, but has yet to begin agility drills. He hopes to put on pads within three to four months, but Jim Harbaugh said the team would err on the side of caution in Lattimore's rehab. Harbaugh even raised the possibility that Lattimore may not play until 2014.
