U23 refers to the age category in sports, particularly in soccer, that includes players who are under the age of 23. This classification is often used in tournaments and leagues to promote young talent and provide them with competitive opportunities. Many national teams, including those in FIFA competitions, have U23 squads to develop future stars. In addition to soccer, the U23 designation is also used in other sports, such as basketball and rugby. These age-restricted competitions help young athletes gain experience and showcase their skills on a larger stage, potentially leading to professional careers in their respective sports.
