49ers second-year running back Marcus Lattimore is still rehabbing and has not been activated to practice.
OC Greg Roman said Lattimore is improving each day.
"He’s looking good," the coordinator said. "Our training staff are the people to ask on that if you want to get specifics... They’re putting him through a lot of change of direction stuff, hard-type cutting. He’s looking good."
Carlos Hyde should be safe as Frank Gore's primary backup. Lattimore has not progressed as quickly as the fantasy community had anticipated.
