Despite losing, the Czech Republic could still reach the quarterfinals of the World Cup if the United States beats Brazil later Monday.
The early result guarantees the Americans of a place in the quarterfinals no matter what they do against Brazil. A Brazil victory would put it in ahead of the Czechs to wrap up the quarterfinal field.
Argentina, Serbia, Spain, Poland, France and Australia had already advanced to the last eight.
Greece led by 12 points early in the final quarter but could not hold the edge over the Czechs (3-2).
Nick Calathes scored 27 points to lead Greece, with 16 more coming from Kostas Sloukas and 12 points and nine rebounds from NBA MVP Giannis Antetokounmpo.
Jaromir Nohacik scored 25 to lead the Czech Republic, while Patrik Auda and Tomas Satoransky added 13 each.
