London club continues to be haunted by injuries - Abou Diaby dropped out of the lineup due to a groin problem.
The midfielder will miss Saturday's English championship match against West Bromwich and will also not be able to help the French national team, which is facing a European Championship qualifying match against Luxembourg next week.
However, Arsenal hopes that the treatment will not take long.
At the moment, coach Arsene Wenger has to manage without key players such as Theo Walcott, Cesc Fabregas, Johan Djourou, Thomas Vermaelen, Wojciech Szczesny, Alex Song and Lukasz Fabianski.
