The Facts: Robinson will miss at least one week of training camp after undergoing arthroscopic surgery on a torn meniscus in his right knee Monday.

Diehards Line:Robinson, the former Penn State QB who has played sparingly in two NFL seasons, was injured during the 49ers’ first full-contact practice Monday morning. Robinson returned to the club’s training complex in the afternoon after the minor surgery, but the 49ers didn’t provide a timetable for his return to practice. Robinson has rushed for just 237 yards and two touchdowns in his NFL career, instead playing mostly on special teams and as a kickoff returner.
