Unai Emery has six Arsenal players on the treatment table ahead of Thursday's Europa League meeting with Vorskla Poltava.
With Danny Welbeck already sidelined with an ankle injury, striker Alexandre Lacazette (groin) is a doubt after missing Sunday's win over Bournemouth.
Elsewhere, full-back Nacho Monreal is sidelined for the next 10 days as he battles back from a hamstring injury.
Stephan Lichtsteiner, who also has a hamstring problem, is back in full training ahead of the trip to Ukraine on Thursday.
Defender Konstantinos Mavropanos will miss out due to a groin strain, while Laurent Koscielny is pushing for a start after recovering from an Achilles injury he sustained back in May.
Earlier in November, Emery offered positive news regarding the Frenchman’s return.
“He feels better in each training,” said Emery of Koscielny.
“He is close to being with us for competitive games. We are happy with him.
“He is with us every day and we are going to think after the international break how we continue working and playing games.”
