The usual field theory of spin 0 "nucleons" coupled to vector mesons (or heavy photons) is studied in order to find out whether the nucleon lies on a Regge trajectory. Photon-nucleon scattering is examined, to each order in the coupling constant, with the highest power of ln cosθ retained. It is found that a suitable Regge trajectory is generated, but that the nucleon does not lie on it. The nucleon pole term in the scattering amplitude corresponds to a fixed singularity in angular momentum. The spin 0 "nucleon" thus behaves differently from a particle of spin ½.
