Eddie O'Sullivan says he would be "amazed" if Ireland's Six Nations match against France goes ahead this weekend.
On Friday, the French Rugby Federation announced that the fixture on 14 March, along with the games involving the Under-20 and Women's sides slated for 13 and 15 March respectively, would not be postponed, nor played behind closed doors, amid efforts to contain the spread of the coronavirus.
However, French health minister Olivier Veran announced on Sunday evening that all gatherings of more than 1,000 people are now prohibited in the country, casting renewed doubt over the likelihood of Ireland's final Six Nations fixture at the Stade de France getting the green light.
Former Ireland head coach O'Sullivan told RTÉ Radio 1's Morning Ireland that he expects Saturday's fixture to be postponed.
"I'd be amazed if it goes ahead because this whole decision-making around the coronavirus is escalating," he said.
"So now that they are tipping it this early in the week, I would be surprised if the game goes ahead at all.
"It's very disappointing but I can't see it getting the green light now."
The spread of the Covid-19 virus across the globe and efforts to contain the outbreak have had an impact on sporting fixtures, with the 2020 Six Nations calendar already hit.
Heading into this weekend's final round of action, Ireland have already had a home match against Italy postponed, while England's forthcoming game against the Azzurri has also suffered the same fate, meaning outstanding fixtures would likely have to be rescheduled for a later date in the year.
"The whole thing would have to be, probably like they did in the foot-and-mouth year, deferred to the Autumn and it's still there I suppose now that France are beaten [by Scotland]," said O'Sullivan.
"But it does change the whole dynamic around it. But I suppose at the moment that's not a priority.
"The priority is public health so I can't see this game going ahead and I would be amazed if the French make an exception for it, considering that the grand slam isn't at stake at all. I can't see that being a runner."
