We study massive graviton propagations of scalar, vector, and tensor modes in the deformed Horava-Lifshitz gravity by introducing the Lorentz-violating mass term. It turns out that vector and tensor modes are massively propagating on the Minkowski spacetime background. However, adding the mass term does not cure a ghost instability in the Horava scalar.
