Newcastle’s European Challenge Cup game against Toulon on Saturday has been cancelled due to coronavirus cases at the Gallagher Premiership club.
Tournament organisers European Professional Club Rugby said Newcastle had informed them they were not in a position to fulfil the fixture at Stade Felix-Mayol.
The Falcons said nine positive Covid-19 tests had been recorded following Newcastle’s European Challenge Cup trip to Biarritz seven days ago.
As a result, Public Health England has advised Newcastle not to travel to France.
Newcastle rugby director Dean Richards said: “It is bitterly disappointing news because we had been looking forward to this important fixture between the two unbeaten teams in our group.
“We understand it will be frustrating for those supporters who were planning to travel out to France, or who had already done so, as well as those looking forward to watching on TV.
“We have taken on board all the relevant advice from Public Health England, and unfortunately it just wasn’t possible for us to fly out to France and play the game in a safe manner.”
EPCR said that a match resolution committee will now be convened to determine the outcome of the game.
