DE Arik Armstead (adductor)
LB Marcell Harris (oblique)
DT Javon Kinlaw (knee)
Armstead, Kinlaw and Harris were all limited Friday, but they’ll all have a chance to go against the Eagles. Harris is the only reserve linebacker on the active roster, so his health is worth watching going into Sunday, and Shanahan never seemed too concerned about Armstead’s hip issue. The big question mark is Kinlaw, who’s been dealing with a knee injury all offseason. It’d be a huge boost for the 49ers’ defensive front if he can play even a limited number of snaps against the Eagles.
