The Serbian centre Nenad Krstic of the NBA's Oklahoma City Thunder has been suspended for three games and fined $75,000 over last week's mass brawl at a basketball tournament in Greece.
Fellow countryman Milos Teodosic and Greek players Antonis Fotsis and Sofoklis Schortsanitis were banned for two games.
The suspensions will keep the four players out of the opening games of the World Championships in Turkey which starts on Sunday.
Krstic was arrested before later being released without bail after allegedly hitting Yiannis Bourousis with a chair as the Greek player tried to break up a fight during the Acropolis Tournament final in Athens last week.
The Argentinia forward Andres Nocioni will miss the World Championships because of an ankle sprain injury suffered in practice.
