As Oxlade-Chamberlain's World Cup appears in doubt, the door may now be open for either Michael Carrick or Tom Cleverly to take their place in Brazil.
Should the scan reveal the worst then the 20-year-old's World Cup dream will be over before it has begun, and England will be required to call upon one of their stand bys to take his place.
The stand out name excluded from Roy Hodgson's final 23-man squad was 32-year-old Manchester United midfielder Michael Carrick.
Although many would argue that Carrick deserves to be in the England squad, he is an entirely different player to Oxlade-Chamberlain and it would be unusual if Hodgson were to call upon the Manchester United midfielder in place of the injured Arsenal star.
Hodgson is more likely to prefer a like for like replacement and in that case the most suitable candidate would probably be Tom Cleverley.
Cleverley has often been at the centre of criticism from both England and Manchester United fans, but the 24-year-old has been defended by Hodgson and may be the most viable option to step up if Oxlade-Chamberlain is ruled out.
All will depend on the outcome of a the scan, the Ox has been in great form of late and was enjoying a superb game against Ecuador before being forced off with injury.
It would be a blow to England's World Cup chances should they lose one of their shining young lights, but you may not hear Michael Carrick or Tom Cleverley complaining should they get the call.
