We perform a one-loop test of the holographic interpretation of the Karch-Randall model, whereby a massive graviton appears on an
AdS

brane in an
AdS

bulk. Within the AdS/CFT framework, we examine the quantum corrections to the graviton propagator on the brane, and demonstrate that they induce a graviton mass in exact agreement with the Karch-Randall result. Interestingly enough, at one loop order, the spin-0, spin-1/2, and spin-1 loops contribute to the dynamically generated
