The San Francisco 49ers will get to see running back Marcus Lattimore and offensvie tackle Luke Marquardt over the next three weeks, as both rookies were cleared to begin practicing. The 49ers placed both rookies on the Non-Football Injury list, and had until Tuesday to trigger the 21-day practice window. If they had not triggered it, both players would have been required to move to injured reserve.
Until now, Lattimore and Marquardt have focused on rehab work. They were not allowed to take part in any practice with the rest of the team, including everything from pre-practice stretching to walkthroughs and normal practice drills. The two players now will be able to take part in all aspects of practice.
Coach Harbaugh indicated previously that Lattimore would take part in certain aspects of practice, while Marquardt would be involved in some kind of participation, but not full-on practices. Lattimore is a year removed from a major knee injury. Marquardt is over a year removed from a foot injury that wiped out his senior year at Azusa Pacific University, but he also had a follow-up procedure on his knee this past April.
The team is plenty content taking their time getting both players back on the field. Neither is expected to be activated to the 53-man roster. Rather, they will "practice" to some extent for the next three weeks, and then be shelved for the rest of the season.
