The National Basketball Association stage its first All-Star Game in the Boston Garden on March 2, 1951. From that year on, the game has matched the best players in the Eastern Conference with the best players in the Western Conference. The participants are currently chosen in two ways. The first is via fan ballot, with the leading vote recipients at each position starting the game; secondly the reserves are chosen by a vote among the head coaches of each squad's particular conference. Coaches are not allowed to vote for their own players. If a player is injured and cannot participate, the commissioner will select a replacement.
