49ers placed RB Marcus Lattimore (knee surgeries), DE Tank Carradine (knee), DT Quinton Dial (toe), and OT Luke Marquardt (foot) on the active/non-football injury list.
Lattimore’s knee issues are well-documented, Carradine is on the mend from ACL surgery, Marquardt underwent foot surgery in April, and Dial had toe surgery in January. Lattimore is the only one that may not do much this summer.
