MIES (Switzerland) - The game schedule and tip-off times have been confirmed for the Men's and Women's Olympic Basketball Tournaments in Tokyo, Japan.

The men's event will take place from July 25 to August 7, and the women's from July 26 to August 8.

With a new format that has 12 teams drawn into three groups in each tournament, the top two national teams from each pool, and the two best third-placed teams, will advance to the Quarter-Finals.

The men's tournament already has USA, Spain, Argentina, France, Australia, Iran, Nigeria and Japan. Four teams that win FIBA Olympic Qualifying Tournaments (June 29 to July 4) in Victoria (Canada), Split (Croatia), Kaunas (Lithuania) and Belgrade (Serbia), will complete the field.

Opening day has two mouthwatering games on the slate, with Australia squaring off against Nigeria in Group B at 17:20 local time (08:20 GMT) and France facing the USA in Group A at 21:00 (12:00 GMT). Australia, seeking their first medal in Olympic competition, will up against one of Africa's most powerful teams in the Nigerians. France eliminated the USA, the three-time defending Olympic champions, in the Quarter-Finals of the FIBA Basketball World Cup 2019 in China.

Another Group Phase game to circle on the calendar is between Spain and the team they beat two years ago in the World Cup Final in Beijing, Argentina. The Group C rivals will play on July 29 at 21:00 (12:00 GMT).

The four Quarter-Finals will be played on Tuesday, August 3, the Semi-Finals on Thursday, August 5, and both the Bronze and Gold Medal Games on Saturday, August 7.
