Argentina have reported three more cases of Covid-19 in their training camp as they continue preparations for the Rugby Championship in Australia.

More than a dozen Pumas players and staff have tested positive for COVID-19 over the last few weeks and the Argentine Rugby Union (UAR) said Julian Montoya, Sebastian Cancelliere and Domingo Miotti had joined the list but were asymptomatic.

Six players, including full-back Emiliano Boffelli and winger Bautista Delguy, had returned to the squad after being given the all clear to rejoin the camp at Casa Pumas, the UAR added.

"There are now 33 players who are able to engage in physical activity," read the statement.

Argentina head coach Mario Ledesma, and assistants Nicolas Fernandez Miranda and Juan Martin Fernandez Lobbe, tested positive last week.

Australia will host the Rugby Championship from 7 November to 12 December.

Dane Coles

All Blacks hooker Dane Coles said today that he has no concerns about heading to Australia for more than two months, joking that he could use the time away from his three children.

The All Blacks are due to head to Australia after two Bledisloe Cup tests against the Wallabies in New Zealand next month.

Biosecurity protocols mean players will be away from their families for about nine weeks.

"I've got three kids, I'll be on that first plane out of here," Coles told reporters in Wellington while laughing.

"It's our job and we've got to go over there, and playing for the black jersey sometimes takes a little bit of sacrifice.

"It's a little bit longer but if you've got to do it, you've got to do it. I'm definitely putting my hand up to go over there and play for the All Blacks."

Coles, who added that he would support any of his team mates who opted not to go, was reluctant to discuss concerns about whether the Championship might not go ahead.

The Argentina squad have been dealing with an outbreak of Covid-19 infections and, like world champions South Africa, have not played since March and would be lacking match fitness.

"I don't want to go into it further because there's that many rumours going on ... right now we've got two weeks of guaranteed footy and that's awesome," Coles said.

"Any rugby, especially All Blacks footy, at the moment would be pretty good."
