Eddie Jones has yet to choose between Semesa Rokoduguni and Marland Yarde over who will start on the right wing for England against the Wallabies at Twickenham this weekend.
The two are competing to replace the suspended Elliot Daly in the climax to the autumn series on Saturday (Sunday AEDT) and – in an unusual move by Jones – both players have been retained in a 25-man squad ahead of Thursday’s team announcement.
The indication from training on Tuesday is that the more experienced Yarde has the edge over Rokoduguni, who was dropped for the 27-14 victory over Argentina after being told he needs to improve aspects of his game if he is to return to Test rugby.
One of the pair will return to his club after the team is named, as will either Dave Attwood or Charlie Ewels with the Bath locks competing for a bench spot against the Wallabies in support of George Kruis and Courtney Lawes.
Nathan Hughes is poised to replace Billy Vunipola at number eight after making a full recovery from a foot injury, with Teimana Harrison continuing as the replacement back row.
Vunipola has been ruled out for at least three months after undergoing knee surgery and could miss the entire Six Nations.
England trained against a backdrop of tightened security around the perimeter of the high performance centre at their Surrey camp as they continued preparations for their quest to secure a fourth successive victory over Australia.
The players were joined by 2003 World Cup winner Will Greenwood, who performed a tracksuit role in the early part of the session.
Prop Joe Marler and fullback Mike Brown did not train due to load management, while Alex Goode return to Saracens with an unspecified ‘leg’ injury.
England 25-man squad retained to prepare for Test.
