Marcus Lattimore thinks he could practice now.

The 49ers, wisely, aren’t going to let him.

According to Ian Rapoport of the NFL Network, 49ers coach Jim Harbaugh said the rookie running back will begin the season on the PUP list, making him ineligible for at least the first six games.

Lattimore was as explosive a back as in the college game in recent years, until a grotesque knee injury which many feared could be caerer-ending. The 49ers were able to take a flier on him in the fourth round because of their stockpile of draft picks, and with a deep backfield, they (and he) can afford to wait.
