England winger Immanuel Feyi-Waboso has been stood down ahead of Saturday's clash with Japan, leaving Steve Borthwick with another selection headache.

The Exeter Chiefs star suffered an ankle injury during England's 45-22 victory over Australia at Allianz Stadium.

Feyi-Waboso was forced off at half-time following a tackle from Angus Bell, who received a yellow card for the incident.

He was later spotted wearing a protective boot, raising concerns over his availability for the remainder of the autumn campaign.

And he wasn't England's only casualty.

Centre Seb Atkinson also departed with a hip problem, leaving Borthwick facing the prospect of reshuffling his backline.

Speaking after the match, Borthwick admitted Feyi-Waboso required further investigation, while Atkinson could also miss the Japan fixture.

An official England squad update is expected later today, when Borthwick should provide further clarity on his available options.

With two potential vacancies, RUCK believes two England A stars have timed their auditions rather nicely.

Two England stars tipped for call-ups

Max Ojomoh

The Bath centre was one of England A's standout performers in their 59-24 victory over Argentina XV on Friday.

Ojomoh scored a try and caused problems throughout with his clever running and distribution.

He earned an impressive 8/10 in RUCK's player ratings.

With Atkinson struggling, the 26-year-old looks an obvious candidate for promotion.

Noah Caluori

The Saracens youngster certainly knows where the try line is.

Caluori crossed twice against Argentina XV, producing another eye-catching performance in an England shirt.

His pace, aerial ability and finishing instincts make him an exciting option to replace Feyi-Waboso.

Borthwick could turn to a more experienced player, but Caluori has made a compelling case.
