Abstract
Most of contemporary thinkers of ethics hold that sport is most influential in both individual and social developments; also, sport in every society reflects the culture of society, and at the same it overshadows cultural, economic, and political problems. Among the problem, one can say that "morals in sports" is a topic which is less dealt with in different societies, including our own society. Surely, what beautifies a sporting event is the manifestation of moral values in relation to rules, rivals, spectators, and officials. At the same time, what persuades a sportsman or sportswoman to observe the values is the presentation of fair game, a subject which needs more discussions. In this article, the authors attempt to examine the attitude of fair game, the interaction between sports and morality and some moral problems in specific fields.
