The priest should say an act of perfect contrition, then he may say Mass. That circumstance would count as a grave reason, so it is permitted under that Canon for him to say Mass.
But it is always the case, whenever anyone commits a grave sin, that they should repent and say an act of perfect contrition as soon as possible.
