The 49ers signed running back Marcus Lattimore to a four-year contract, the team announced Friday afternoon.
Lattimore was a fourth-round pick, the No. 131 overall pick in the NFL draft. The 49ers have now signed all but two of their 11 draft picks. Only safety Eric Reid, a first-round selection, and outside linebacker Corey Lemonier, a third-round pick, remain unsigned.
Lattimore sustained a season-ending knee injury in October as a junior at South Carolina. He dislocated his right knee and sustained tears to three knee ligaments. He has yet to be cleared for on-field work.
The 49ers are expected to place Lattimore on the non-football injury list at the opening of training camp. Lattimore might not play for the 49ers this season.
In 29 games over three college seasons, Lattimore gained 2,677 yards rushing.
