We study the structure of a family static, spherically symmetric space-times generated by an anisotropic fluid and governed particular type f(R) theory. find that for range parameters with physical interest, such solutions represent black holes central singularity replaced finite size wormhole. show time-like geodesics null nonzero angular momentum never reach wormhole throat due to infinite potential barrier. For radial geodesics, it takes affine time This means resulting space-time is geodesically complete and, therefore, nonsingular despite generic existence curvature divergences at throat.
