Wing Tom Roebuck is a doubt for England’s trip to Fiji on Saturday after missing training on Tuesday with an ankle injury.
Roebuck played a key role in two of England’s tries as they ran out 25-7 winners over the Wallabies at the weekend.
Full-Back Freddie Stewed is also training this week after picking up a hand injury in the closing stages of the wallbies’ win.
Head coach Steve Borthwick will confirm his Intermediate squad on Thursday as England look for their ninth win.
If the agent is not available for selection, Marcus Smith is a contender to start in the 15 after missing out on the squad at the weekend.
Smith, name of Fin, and Cap Centurion George Ford are the three halves of the wider Kevin Sinfield claims that all happy is a challenge.
“You’re not, you’re not [keep them all happy]”Sinfield told BBC Sport.
“But that’s what it should be. At this level there is always someone who is a little impatient or has a little frustration. They are all impatient because they all want the dress now.
“But they are all good people who understand the value of the team. Of course it will take some management but they understand the times when they get bad news, and they have to work like everyone else.”
And Sinfield says that Marcus Smith will be more than happy to fill in again in full return, where he has shown up regularly in the last two years.
“He always said he was a 10, but he understood that – if you look at all sports – the best players don’t always play for their clubs,” Sinfield said.
Meanwhile, Sinfield says it’s only a matter of time before Henry Pllock makes his first start for his country.
Pollock made a couple of dominant appearances off the bench, scoring two tries against Wales in March and a game-winning score against Australia.
“He’s very confident and fully believes in his ability. He’s a great person around the team, he’s different, but he brings energy and enthusiasm,” said the Sinfield man.
“To get all the things he has as a 20-year-old is amazing. He will keep trying to get better and better before he starts for sure.”
