The second round of the Trailfinders Challenge Cup between Saracens and Doncaster Knights has been cancelled.
The decision follows after two members of the Saracens squad were tested positive for Covid-19 and 16 other players in the squad were placed in isolation leaving them short of the matchday squad.
"Following its weekly PCR Covid-19 testing programme, two Academy players have returned positive results with a further 16 members of the squad having to isolate due to contact tracing," read the statement.
"It means Sarries are without 34 players for the match at Castle Park on Saturday because of injury, suspension and isolation and are therefore unable to field a side.
"The club did everything it could in its attempts to name a 23, but two additional players today being contacted to isolate meant this was not possible.
"Those players and staff who have tested positive, or who are traced as contacts of those testing positive, will isolate for a minimum of 10 days with the wellbeing of club staff, players and their families paramount."
As a result, Doncaster are set to be awarded a win and four points while Saracens are set to receive two according to the revised guidelines for the Covid affected matches.
