The Gold Coast Titans' training numbers were lowered to just 14 players on Friday as a majority of their squad are currently placed in isolation.
All three Queensland clubs have had players and staff forced to follow the state's COVID-19 health and safety protocols after either contracting the virus or being listed as a close contact.
The Broncos have had as many as 16 players test positive for the virus, while the Cowboys have had 10 positive tests of their own.
Now, according to The Gold Coast Bulletin, 23 Gold Coast players are currently in isolation, leading to a small showing at Titans training this week.
The Titans released a statement on Thursday in regards to the outbreak ahead of their return to training.
“Like many organisations, we have been impacted by the current outbreak, but we are working with the NRL on a safe return to training,” Titans boss Steve Mitchell said.
“The health of our staff, players and community is a priority and we will be following the NRL’s Apollo protocols to allow our players to safely resume training.
“Once players are cleared they will return under the NRL's graduated return to play guidelines."
Star forward David Fifta was among those not in attendance at training, as per the News Corp report.
The Titans join their local rivals, as well as the Panthers and Knights, in having a significant number of players currently in isolation.
More than 100 NRL players have reportedly tested positive for the virus, with that number growing rapidly as clubs make their return to pre-season training.
