Very few clubs are avoiding Covid-19 disruptions as the Heineken Champions Cup teams prepare for round two.

Among those hoping to build on an excellent start are Ulster, who welcome Northampton to the Kingspan Stadium on Friday night, fresh from a scintillating 29-23 win over Clermont away.

The Saints, conversely, must pick themselves up after a 42-6 home loss to Racing 92.

But coronavirus hovers overhead across all team sports and assistant coach Dan Soper was asked what it's like to deal with the persistent threat of cancellation.

"Look, all we can control is our own environment and how we go about our preparations, how we go about preventing that from impacting on us," said the New Zealander, whose own team had to do without Duane Vermeulen for a recent URC match.

"That's a very difficult thing because unless you put players on a very tight leash that restricts their lives, they have to be people and get out there, be with their families that are coming back from school and from work.

"The guys over the past couple of years have been excellent in how they've done things, they've been very sensible with the protocols and following all the protocols that the majority of people are.

"We can only control what we can control. I guess there's a bit of luck involved as well."

Leinster were another side hit by a small outbreak in the camp last week.

Three unnamed players missed the win over Bath and Monday's planned training session was postponed due to further rounds of testing.

The four-time champions face a Friday trip to Montpellier who yesterday were reported to have two players test positive.

"That’s why all the tests and everything are in place," said Leinster back row Rhys Ruddock (above) when asked how the playing staff deal with all the uncertainty.

"We realise it’s not an issue for everyone that is negative and able to continue.

"Obviously in an ideal world you don’t have any but it is just the world we are living in now and it’s all around and we all have a responsibility to make sure we are aware of that and do our best to avoid it."

Meanwhile, Ulster will issue an injury update later today but Soper does not expect Robert Baloucoune to be fit for the game after suffering a shoulder injury against Clermont.
