San Francisco 49ers free safety Jimmie Ward strained his hamstring on Thursday during the conditioning test, and that resulted in a depth chart shake-up. The team played Jaquiski Tartt as the first team free safety.
Kyle Shanahan said after practice that Ward tweaked his hamstring halfway through the conditioning test. The trainers did not think it was a full pull of the hamstring, but they want to play it safe and avoid creating a bigger problem.
Tartt is someone I think a lot of us have viewed as primarily a closer to the box guy. It makes sense to cross-train him at both safety positions, but I imagine once Ward is back (hopefully sooner rather than later), Tartt will return to more of a box role. The 49ers also have rookies Lorenzo Jerome and Adrian Colbert, as well as special teams safety Don Jones competing back there. While Ward remains sidelined, I would not be surprised to see one or more of them get some first team work as well.
