The conditions and restrictions of the Men's Basketball World Cup on the players of the participating teams mainly include the following points:
Eligibility: Teams participating in the FIBA must be a member or region of the International Basketball Federation (FIBA) and must qualify through a continental qualifier. Each team must submit a list of eligible players who are citizens of the country or region or have legal eligibility to compete.
Age and status: In the Men's Basketball World Cup, there is usually no specific age limit for players, but players are required to be non-professional, i.e. they cannot have basketball as their primary occupation or income**. However, this rule has been relaxed over the past few years and some professional players are now allowed to play, but the specific rules may vary depending on the tournament and year.
Health: Players must be in good health, free of serious injuries or illnesses, and able to complete the game. Before the game, teams will need to submit a player's medical certificate to ensure they meet the requirements to participate.
Team size: There is a certain number of players per participating team, usually including 12 players and a certain number of substitutes. Teams must submit the final roster of players within the allotted time, and these players must remain on the roster for the entire duration of the tournament.
Disciplinary requirements: Players must abide by the disciplinary rules and rules of the game of the International Basketball Federation. Any violation of the rules, such as violence, immoral behaviour or doping, will result in appropriate penalties, including bans, fines or disqualification.
It is important to note that the above conditions are general and may vary depending on the year of the competition, the host country and the policies of the International Basketball Federation. Therefore, before participating in the Men's Basketball World Cup, teams and players need to carefully understand and comply with the relevant regulations and requirements.
In addition, FIBA also has rules for naturalized players (i.e. players who were not born in their own country to represent another country through naturalization, etc.). Each team participating in an official FIBA tournament can only have a maximum of one naturalized player who is at least 16 years old, and if a player has represented a team in an official FIBA tournament after turning 17, he or she will not be eligible to represent another team even if he or she has completed the naturalization process. But the FIBA Secretary-General can give the green light in certain exceptional circumstances.
