Even with the injuries at running back, the 49ers are taking their time with first-year player Marcus Lattimore.
Lattimore continues to rehabilitate his surgically repaired right knee and a hamstring strain he sustained during the offseason program.
Lattimore is close to being activated the team said. Lattimore spent last season on the NFI list. Yes, his knee injury was sustained during a football game, but it was not during his employment with an NFL team. Because the injury was sustained in college, prior to joining the 49ers, and he never was on the team's 53-man roster as a rookie, he did not accrue an NFL season.
