Running back Frank Gore did not participate in practice on Tuesday, as he arrived at the team facility after a visit to a doctor as part of the NFL’s protocol on concussions.
Gore must pass the designated steps in order to be available for the 49ers’ game Saturday night against the San Diego Chargers.
Gore did not play in the second half of the 49ers’ 17-7 loss to the Seattle Seahawks on Sunday after sustaining a concussion in the second quarter while blocking linebacker Bobby Wagner.
The story also said backup running back Carlos Hyde was also not seen on the field at the beginning of practice after sustaining right ankle and back injuries on a third-quarter play during Week 15. Right now, Alfonso Smith and Bruce Miller are the only other RBs on the 49ers roster. The 49ers play the Chargers on Saturday night so both backs lose a day as they try to get back on the field.
