چکیده	In this paper, we investigate the behavior of linearized gravitational excitation in the Born–Infeld gravity in AdS3 space. We obtain the linearized equation of motion and show that this higher-order gravity propagate two gravitons, massless and massive, on the AdS3 background. In contrast to the R^2 models, such as TMG or NMG, Born– Infeld gravity does not have a critical point for any regular choice of parameters. So the logarithmic solution is not a solution of this model, due to this one cannot find a logarithmic conformal field theory as a dual model for Born–Infeld gravity.
