Sydney Roosters players have been tested for COVID-19 and staff told to stay home after a known case visited venues through the city's eastern suburbs.
Players were on Thursday morning rushed in for tests, some 36 hours out from Friday night's NRL clash with Parramatta.
The main concern centres around the infected man's visit to the Azure Cafe on Monday, less than 100 metres from the Roosters' headquarters.
The Moore Park cafe in the Entertainment Quarter is a popular coffee stop and lunch venue for both Roosters and Sydney Swans AFL players, as well as sports officials.
Working in the Roosters' favour is that players had been sent home early from training on Monday after confirmation of Brett Morris' ACL injury.
It's believed no Roosters players or staff were in the cafe at the time of the infected man.
The tests have, however, put a spanner in the works of preparations for their game against the Eels, with the club usually running through a session on the day before games.
Beyond Friday night's game, there was at least some good news for the NRL on Thursday after NSW's first case of community transmission in months.
Crowds won't be slashed for games in round nine, with seated areas still at 100 per cent and hills restricted to one person per two square metres.
"They're an outdoor events and absolutely they should go ahead," NSW Premier Gladys Berejiklian said.
"Outdoor gatherings are very low risk.
"The strongest message we are sending is it's business as usual."
The Queensland government also opted against shutting the border to NSW, with Magic Round due in Brisbane next weekend.
That event will likely rely on case numbers over coming days, with Queensland's first move to quarantine anyone who has been to case locations in NSW.
