Jack Wilshere will see a specialist to assess his ankle injury, Arsenal manager Arsene Wenger has announced.
Wenger confirmed that Wilshere would be "out for a while" after coming off during the 2-1 defeat by Manchester United on Saturday after feeling some discomfort.
Wilshere, who was replaced by Santi Cazorla in the 55th minute of the game at the Emirates Stadium, will therefore miss the Champions League clash with Borussia Dortmund on Wednesday.
Wenger did confirm, however, that Laurent Koscielny is back in the squad following an Achilles problem and Danny Welbeck is expected to be included, although striker Oliver is not registered and Theo Walcott is still ruled out.
Just days after England manager Roy Hodgson admitted he was keeping an eye on Manchester United's new teen sensation Adnan Januzaj, England midfielder Jack Wilshere said he believed only English people should be able to play for the national team.
Wilshere said:"The only people who should play for England are English people.
"If you live in England for five years it doesn’t make you English. If I went to Spain and lived there for five years I’m not going to play for Spain."
Arsenal midfielder Jack Wilshere has tweeted a picture of England's new home kit.
