USA Basketball (USAB) has confirmed that Saturday's exhibition game between the United States and Australia has been cancelled due to growing COVID-19 fears.

The two sides were due to meet for the second time this week as part of their preparations for the upcoming Tokyo Olympics.

The cancellation comes after USAB confirmed on Thursday that two players had entered health and safety protocols.

Washington Wizards guard Bradley Beal had been ruled out of the Olympics after entering protocols, while Jerami Grant was also placed under protocols, as a precautionary measure.

Team USA are still scheduled to play Spain in Las Vegas on Sunday in their final preparation game before flying for Tokyo on Monday.

USA's opening game at the Tokyo Olympics is on July 25 against France, while Australia commence their Games campaign on the same day against Nigeria.

Australia had shocked USA 91-83 on Tuesday, following their upset defeat to Nigeria on Monday.
