We analyze s-wave pion-nucleon scattering in a unitarized chiral effective Lagrangian including all dimension two contact terms. We find that both the S-11(1535) and the S-11(1650) are dynamically generated, but the S-31(1620) is not. We further discuss the structure of these dynamically generated resonances.
