Semesa Rokoduguni and Marland Yarde have been retained in England's 25‑man squad to prepare for Sunday's match against Australia at Twickenham.
The pair are competing for the wing spot vacated by Elliot Daly, who has been banned for three weeks.
Yarde is thought to be the favourite to replace Daly, while Nathan Hughes is the likely option at number eight with Billy Vunipola injured.
Coach Eddie Jones will name his matchday squad of 23 on Friday.
Hughes missed England's win over Argentina because of a foot problem
The Fiji‑born Wasps forward has won two caps as a replacement, but has yet to make a first international start.
The Wallabies meet England at 3.30am Sunday.
