Tokyo Olympics: Australia fumes at 'heartbreaking' Opals vs China robbery

The Opals' Olympic dream are hanging by a thread after a shocking call spoiled an all-time comeback against China.

Saya Sakakibara was taken to hospital.

It was another golden day of Olympic action for Australia, but there was some mixed luck for our teams.

The Matildas will have two cracks at their first ever Olympic medal after securing passage to the women's football semi-finals with a gripping 4-3 extra time win against Great Britain.

Sadly, the Opals suffered a cruel loss to China because of a controversial refereeing call at the death, putting them on the brink of exiting the Games early.

Earlier, Emma McKeon won her first individual gold medal in a thrilling final of the women's 100m freestyle, which saw Cate Campbell banish her demons from Rio and finish with bronze.

However, that elation was followed by the most heartbreaking moment of the entire Games when Aussie star Saya Sakakibara suffered a terrifying crash in the semi-finals of the women's BMX Racing event.

It was also a tough day for Ash Barty. The Aussie star lost her mixed doubles semi-final with compatriot John Peers and will now play off for the bronze medal, while Patrick Tiernan made himself a hero just by finishing the men's 10,000m race.
