In this paper, we study a restricted modified gravity in which diffeomorphism symmetry is broken. We investigate the astrophysical implications of the model by using the corresponding gravitational potential. By using the weight function of the weak lensing , for the model, the deviation of the model with respect to model has been studied for the late-time cosmology.
