The 2010 FIBA World Championship included 24 teams that competed in Turkey between August 28 and September 12, 2010. Each team selected a squad of 12 players for the tournament. Final squads for the tournament were due on August 26, two days before the start of competition. Angola and the United States were the only teams made up of entirely domestic players (Jordan and Russia each had 11 domestic players). Slovenia and Canada were the only teams composed entirely of players playing outside the domestic league, although at the time of the tournament Canada had no pro league exclusive to the country, instead competing in several U.S.-Canada cross-border professional and semi-professional leagues. Forty-one National Basketball Association players were selected to compete in the tournament, the most of any league. In all, thirty countries had at least one player from their league system participate in the tournament.
