Canterbury centre Jake Averillo has been stood down by the club after becoming inadvertently caught up in the COVID-19 cluster at the Crossroads Hotel in Casula.
Averillo told the Bulldogs that his parents had a meal there on July 3 and will be tested for the virus.
The club has notified the NRL and is awaiting directions on the next biosecurity steps to be taken.
In the meantime the rookie outside back has been stood down from all training and playing duties.
Averillo, who made his Telstra Premiership debut in round two just before the competition went into a two-month hiatus because of the pandemic, did not play last Saturday in the loss to Brisbane.
Due to the outbreak at the Crossroads Hotel in Casula, in south-west Sydney, NSW Health has advised anyone who visited the pub between July 3 and 10 to self-isolate and get tested.
Bulldogs forward Aiden Tolman missed two matches last month after one of his children attended a school which had a staff member that tested positive.
The club is yet to make an official comment on Averillo's status but is likely to do so on Monday afternoon.
