Saracens have forfeited their European Challenge Cup game against Pau following a Covid-19 outbreak at the Gallagher Premiership club.
Tournament organisers European Professional Club Rugby said a 28-0 scoreline and five match points had been awarded to the French club, who were due to host Saracens on Saturday.
EPCR added that Saracens had informed them of a “significant number” of positive Covid-19 tests among their playing squad, meaning they could not safely fulfil the Pau fixture.
Saracens said that the outbreak had occurred within their training ground environment, reporting “several positive Covid cases” from a latest round of PCR testing on Monday.
In a statement, Saracens said: “The club has taken the immediate action of closing the training ground and isolating all players, coaches and support staff.
“We have been working closely with EPCR and PRL (Premiership Rugby) and it is with regret that our game versus Section Paloise (Pau) in the EPCR Challenge Cup on Saturday 18th December has had to be forfeited by Saracens due to our inability to field a 23-man squad for this fixture.
“In addition to positive Covid-19 cases, we have players self-isolating due to being close contacts, and a number of players who are currently injured.
“This is extremely disappointing for everyone at the club, but as always the health and well-being of our people is our priority at this time.”
Saracens said that the squad would return to full training on December 24th.
“We would like to reassure our supporters that our Gallagher Premiership fixture versus Worcester Warriors on 26th December will still take place,” the club added.
Meanwhile, Bath have postponed training after returning a “very small number of positive results” and will only resume after the next round of testing.
Bath host La Rochelle at the Recreation Ground on Saturday after losing 45-20 at Leinster in their tournament opener.
