Students who have not used or are not using their athletic skill as players for financial gain, or who have not competed under assumed names as players, shall be considered amateurs. Employment as an instructor, counselor, or official may not be considered a violation. Students who have ceased to be amateurs in a particular sport may not represent their school in interscholastic athletics in that sport. Students who have lost amateur standing may apply for reinstatement to the MPSSAA Appeals Committee after the lapse of 60 days. The 60 days shall commence with a letter of determination from the local superintendent of schools. Students may not lose amateur standing by playing with or against professional players as long as they do not receive pay for their services. Students shall lose their amateur status in a particular sport if they sign a professional contract in that sport.
