Catalans Dragons' home game against Leeds Rhinos in Super League, set to take place on September 7, has been postponed.
The announcement was made as the French club continue to quarantine after it was confirmed this week that three players and one member of staff had tested positive for coronavirus.
Saturday's clash with Wigan had already been called off following the news, though the Warriors will still be in action against Castleford Tigers instead.
Super League has now announced that with the Dragons needing to continue isolating, Leeds will not be visiting as planned early next month.
"It is now confirmed, following consideration of all the available health information, that all Dragons squad members must isolate for 14 days - a duration which takes them beyond the scheduled fixture with Leeds Rhinos," a statement read.
"A decision on rescheduling the Catalans Dragons versus Leeds Rhinos game will be made in due course, and the RFL [Rugby Football League] and Super League will now actively explore all available options to avoid any further disruption to the fixture calendar."
The Rhinos had initially been due to travel to Perpignan in March to play the game behind closed doors, only for one of their players to show symptoms of COVID-19, forcing a postponement.
