Gloucester have ceased training and called off this weekend's Gallagher Premiership match against Bath after a coronavirus outbreak at the club.
The Cherry and Whites beat London Irish 30-28 at Kingsholm on Friday evening and were due to host Bath on Saturday afternoon.
The club said: "Gloucester Rugby have taken the decision to stop all training following a Covid-19 outbreak within the camp.
"Therefore, our game with Bath Rugby this weekend has been called off.
"We are wishing all of our players and staff affected by this outbreak a speedy recovery."
Under Premiership regulations, the match with Bath will be cancelled and a panel will determine the allocation of points.
A Premiership Rugby spokesperson said: "Our priority is the health and safety of everyone involved with Gloucester Rugby and Bath Rugby and we will give the clubs any support they need. We wish everyone affected a full and speedy recovery.
"Neither Premiership Rugby nor the club will be naming any of the players or staff involved and we'd ask everyone to respect their privacy."
