Marcus Lattimore has signed a four-year contract with the San Francisco 49ers.

Lattimore was considered a steal for the 49ers in the fourth round, but he is still recovering from three torn ligaments and a dislocated right knee.

"I just want to train as hard as I can," Lattimore said. "But I understand why they want me to slow down."

Lattimore said that being around Frank Gore is inspiring as he overcame major knee surgeries in college.

"It was great to finally meet him in person," Lattimore said. "He's been wonderful to me."
