Bristol have been awarded full match points for their Heineken Champions Cup opener against Scarlets.
The Welsh side have informed tournament organisers that they would be unable to field a team for their opening pool match, which had been scheduled for Saturday 11 December at Ashton Gate.
Scarlets' entire 47-person group will remain in quarantine in Belfast until the day before the game, having returned from their abandoned tour of South Africa last week.
With the Scarlets players unable to train, the club have informed the EPCR that because of "player welfare concerns and the club's inability to safely field a match day squad", they would not be able to fulfill the fixture.
As a result, Bristol have been awarded a 28-0 bonus point win, worth five match points.
Munster remain committed to fulfilling their way trip to Wasps on Sunday, despite also being affected by a large group of players being in home-isolation until the day before the game.
However, it does look like the province will be able to field a team, with their frontline international players, and several academy players having stayed behind in Ireland rather than travel with the group to South Africa.
"Scarlets, Bristol Bears and EPCR used their best endeavours to stage the match, however, this has not been possible and it is regrettable that the fixture is now cancelled," a statement from the EPCR reads.
"EPCR acknowledges the unfortunate circumstances which have impacted on Scarlets' players and staff through no fault of their own, and would like to emphasise that awarding the match to Bristol Bears is a tournament management measure with the objective of ensuring that all fixtures in the 2021/22 Heineken Champions Cup are accounted for.
"EPCR has been in regular dialogue with Scarlets in recent days to offer guidance and support, and best wishes are extended to everyone at the club."
