Which of the following actions is prohibited regarding player equipment?

Using dangerous items is explicitly prohibited in soccer to ensure the safety of all players on the field. Items that could potentially cause injury, such as jewelry (including rings, bracelets, and earrings), or any sharp objects, cannot be worn during a match. The integrity of the game and the well-being of the players are paramount, which is why this rule is strict.

Wearing clothing of a different color is also not permitted because it can lead to confusion about team identification during the match. Teams are required to wear uniforms that clearly distinguish them from one another, contributing to the clarity of the game for players, officials, and spectators.

Thus, both the use of dangerous items and wearing clothing that may not conform to established requirements are actions that compromise safety and uniformity; therefore, they are both considered prohibited. By identifying these issues together, it shows a comprehensive understanding of the regulations surrounding player equipment.
