Currently, only one player in the NBA wears the number "6" jersey.
According to Idman.biz, citing ESPN, the NBA announced that the number "6" jersey would be permanently retired in honor of Bill Russell after the legendary basketball player's death in 2022.
However, players already playing under this number can keep it until the end of their careers.
With DeAndre Jordan's departure from Denver, Oklahoma City player Jalen Williams remains the only active player in the league wearing number six. When he finishes his career, this number will be permanently retired from the entire NBA.
