  Massive gravity previously constructed as the spin-2 quantum gauge theory
leads in the mass zero limit to a modification of general relativity. As a
relic from the massive theory a vector field v survives which couples to the
metric only. However, the coupling does not involve covariant derivatives so
that v must be considered as 4 scalar fields. We analyse the static,
spherically symmetric solutions of this theory. From the corresponding
geodesics we find the circular velocity profile. Interpreting this as coming
from a dark density profile, the theory predicts a flat density core for r
going to 0. But the dark density profile is not universal.
