It has been conjectured that in head-on collisions of neutron stars (NSs), the merged object would not collapse promptly even if the total mass is higher than the maximum stable mass of a cold NS. In this paper, we show that the reverse is true: even if the total mass is less than the maximum stable mass, the merged object can collapse promptly. We demonstrate this for the case of NSs with a realistic equation of state (EOS) (the Lattimer-Swesty EOS) in head-on and near head-on collisions. We propose a ``prompt collapse conjecture'' for a generic NS EOS for head-on and near head-on collisions.
