Thailand, however, still hope to remain in the tournament as there are four more places for best third placed teams from six groups when all preliminary rounds are over on Tuesday.
"We played well for three games but we just couldn't get the ball into the goal. We hope that miracle will happen and get us a chance to still remain in the Games," said national coach Worrawoot Srimaka.
Meanwhile, the women’s team lost to Vietnam 2-3 in Group C last preliminary round. With Japan and Vietnam advancing , the women's team also hoped for best four third placed spots.
