Arsenal manager Mikel Arteta confirmed after the defeat to Chelsea that Kieran Tierney picked up a quad muscle injury, and the Scottish international is now a doubt for the matches against West Brom and Manchester City.
Gabriel Martinelli suffered cramp before being replaced by Folarin Balogun ten minutes from the end of the game on Sunday but the Brazilian should be available for selection pretty soon.
Alexandre Lacazette has still not trained after suffering from the effects of the virus and remains a major doubt for the weekend. Ben White has already been ruled out by Arteta ahead of the City clash, having tested positive before the Chelsea match.
Hector Bellerin has a thigh issue, which will likely rule him out of contention for upcoming games, while Eddie Nketiah (ankle), Gabriel (knee) and Thomas Partey (ankle) are not expected to feature for the Gunners again before the next international break.
