49ers rookie quarterback Colin Kaepernick was a full participant on the first day of an informal minicamp Tuesday, showing off his strong arm and moving swiftly for the first time since surgery on his lower left leg in early May. Kaepernick said he doesn't feel limited at all but is waiting for an upcoming doctor's appointment before he resumes his complete training program. "Definitely have to get back a little of the timing, get back to the pace of the routes, the timing of certain things," he said. "That's just going to take a little bit of time. For the most part, I felt like I was on time with most of my throws today and felt good out there." Kaepernick, the 36th overall pick, decided to skip a symposium for NFL rookies this week to spend time with his San Francisco 49ers teammates and learn some of the playbook.
