The San Francisco 49ers drafted a running back in the second round of last week's draft, but that doesn't mean Marcus Lattimore has suffered a setback.

Lattimore tore three ligaments in his left knee in October 2012 and spent his first NFL season rehabbing.

“It’s been going good,” Lattimore told 49ers.com on Thursday. “I’m real happy because I’ve had no knee problems, nothing in my knee, no soreness, no swelling.”
