COLUMBIA, S.C. (AP) - San Francisco 49ers running back Marcus Lattimore is confident he can finally contribute on the field this season.

Lattimore has worked through several of San Francisco's offseason training workouts without problems to his surgically repaired knees. He missed the final six games of his sophomore season in 2011 because of a left knee injury that required surgery. Lattimore tore ligaments in his right knee the next season, also ending his year prematurely and requiring surgery.

Lattimore declared for the draft and was selected by the 49ers. He sat out last year recovering and entered this spring eager to make an impact on the field.

So far so good.

Lattimore says his knees have held up and he's ready for contact.
