NBA superstar Giannis Antetokounmpo sat out Greece's final FIBA World Cup warm-up match against Venezuela on Tuesday.

The Milwaukee Bucks forward is set to be his country's main man at the tournament in China after an outstanding season in the United States in which he was named MVP.

But Antetokounmpo was not available to face Venezuela after complaining of irritation in his knee and opted not to take the risk with the World Cup beginning on Saturday.

Thanasis Antetokounmpo, Giannis' brother, had been dealing with a foot problem but was included in the team.

Greece begin their World Cup campaign against Montenegro on Sunday, with further group stage games against Brazil and New Zealand following next week.
