The San Francisco 49ers wrapped up their first day of on-field practice for Week 15 vs. the Seattle Seahawks, and a few players of note are banged up. Cassius Marsh is in the concussion protocol, and Jaquiski Tartt (shoulder) and K’Waun Williams (knee) remain sidelined.
Marsh will go through the normal protocol, which means he will have to be asymptomatic at rest, then asymptomatic after a workout, and then get through a contact test. Thursday and/or Friday will give us a better idea of Marsh’s status.
