Illness rips through Wallabies camp
Israel Folau, Bernard Foley and Adam Coleman have been isolated from teammates in the Wallabies' camp after contracting stomach bugs.
The virus has affected up to 10 players and spread to staff in the team, but most have recovered.
Folau was only able to eat his first meal in several days on Tuesday morning.
They caught the bug in Italy but managed to play in Saturday's match before boarding the plane to London when teammates were alerted.
Folau and Foley have not trained this week and Wallabies defence coach Nathan Grey said they would be monitored closely.
"There was a few guys crook through the Italy game, a few played through and then a few guys missed out at training yesterday," Grey said.
"I think it's something that, it happens when you're touring.
"Squizz (Folau) had a bit of stuff floating through and then Bernard and a few of the other boys just missed out training yesterday. Adam, yeah, it's not ideal but shit happens.
"The funny thing is a few of the staff have got it as well so that's always, that's funny. Players not so funny.
"The guys who have been crook are isolated. They're being looked after by the doc and everyone's getting on with it.
"It's part of footy, so just got to get on with it and those guys, no one's going to die. So, it's just get their fluids back up, hydrate and get ready to go.
"A few guys won't train today. The guys who are ready to go, the doc will green light them and then they're on."
Grey said the absences at training was not ideal in the build-up to Saturday's showdown against England at Twickenham, but would allow others to press their claims.
"You get to this time of the year on a tour and everyone's pretty across the way that we want to play and then at training yesterday, we've got guys dropping in at different positions which are great," Grey said.
"We've got the luxury in the squad as well of having guys who can play multiple positions, can play up in the front line, backfield.
"It actually provides a bit of an opportunity to see how those guys are going in those situations and it gives us lots of opportunities and headaches around selections, depending on what we're going to cop on Saturday.
"We saw under the roof in Wales, nice dry quick track and we've seen, we all know what Twickenham can be like.
"So a little bit of illness has forced us to have a bit of a look at how we can do things and we've got a bit of luxury with some guys to mix it up."
All players participated in Tuesday afternoon's training session.
