The NBL has had a major COVID-19 scare after two players tested positive for the virus.
Training for the two Melbourne teams - United and South East Phoenix - was suspended immediately on Wednesday after United duo Mitch McCarron and Jo Lual-Acuil returned positive COVID-19 tests.
All United players and staff who attended training sessions on or after July 22 will now be tested and self isolate for 14 days, even if a negative test is returned.
"Our concern is for players and staff and ensuring that we follow the right protocols to minimise any further risk to the wider community. We are providing support for both clubs, in particular those players who have returned positive tests," NBL Commissioner Jeremy Loeliger said.
"We have decided it's in the best interests to also suspend South East Melbourne training as a precautionary measure. Given the current situation in Melbourne we do not want to take any risks and we will continue to work with the relevant health authorities to ensure all protocols are followed."
Hawks coach Brian Goorjian and new marquee recruit Deng Adel are both based in Melbourne.
