  We complete the Hamiltonian analysis of specific model of non-linear massive
gravity that was started in arXiv:1112.5267. We identify the primary constraint
and corresponding secondary constraint. We show that they are the second class
constraints and hence they lead to the elimination of the additional scalar
mode. We also find that the remaining constraints are the first class
constraints with the structure that corresponds to the manifestly
diffeomorphism invariant theory. Finally we determine the number of physical
degrees of freedom and we show that it corresponds to the number of physical
modes of massive gravity.
