This review of ethical implications of the professionalisation of sport argues that conventional sports ethics, which in the spirit of amateurism emphasise concepts of fair play, are increasingly inappropriate in professional sport. The formalist position, that fair play requires playing within the rules, is explored as are notions of playing to the rules, gamesmanship and cheating. It is argued that ethical problems in elite sport increase as a result of external factors including the celebrity of sportspeople, a tarnished image of (...) some administrators, influences of external stakeholders , and the expectations of fans. Hence a worryingly negative picture of declining ethical standards in the face of internal and external pressures emerges, with little prospect of sports reforming from within, despite that appearing to be in a sport's best interests.
