The Sunwolves won't be able to host next month's game against the Brumbies in Tokyo.

Coronavirus prevention measures will come into play at Super Rugby venues, with governing body Sanzaar making special mention that Sunwolves players taking on the Hurricanes in Napier on Saturday have shown no symptoms of the virus.

Growing concern over the spread of coronavirus in Japan has led to its government requesting that all sports events due to be held in that country in the next two weeks be cancelled.

That means the Sunwolves' following game, against the Brumbies in Osaka on March 6, will not be held there, and Sanzaar is looking to relocate the match.

Sunwolves boss Yuji Watase later confirmed the Crusaders' match against the Japanese side, on March 14, wil not be held in Tokyo as scheduled.

Sanzaar is stepping up its monitoring of all Super Rugby players and officials in the wake of the global spread of the disease.

GETTY IMAGES Hurricanes head coach Jason Holland says the franchise will take the lead from New Zealand Rugby over coronavirus measures.

"Daily review and monitoring of all participants is now in place under an agreed protocol," it said in its statement on Thursday.

"In terms of the Super Rugby tournament as a whole, management is in regular and close contact with the National Union Chief Medical Officers (CMOs) who have been monitoring teams within their own territories against national health guidelines and health authority directives," Sanzaar said.

"Advice from the CMOs is that within the participating Super Rugby countries there are presently no identified cases of any players, management or match officials [or family members] presenting symptoms associated with the virus, including the Sunwolves.

Under their protocols, the medics will ensure sanitisation stations are set up at all team venues and that players and staff have their temperatures checked.

Contact and treatment plans are being drawn up by each national rugby union to assist visiting teams and the monitoring of match officials.

Hurricanes coach Jason Holland said there were no concerns ahead of this weekend's game.

"We have to acknowledge it. It's obviously having a big impact on the game around the world, in the UK there are games being called off, but we'll take our lead from New Zealand Rugby on that. It's something we're aware of."

Sanzaar said it would issue further details over the Sunwolves-Brumbies match "and any potential further disruptions" in the near future.

It was also announced on Thursday that next weekend's Six Nations game between Ireland and Italy in Dublin has been postponed because of an outbreak of the coronavirus in northern Italy.​
