I've signed a contract outside the Match. What happens now?
Under the terms of the Match Participation Agreement, an
independent applicant who accepts a position outside the Match must withdraw immediately. Failure to do so is a material violation of the Agreement and will be investigated by the NRMP in accordance with the Policies and Procedures for the Reporting, Investigation, and Disposition of Violations of NRMP Agreements.
