The 25-year-old suffered the problem during the Gunners' 1-1 draw with Stoke City on Saturday after an injury-plagued season.
The North London club are yet to confirm the injury blow, suggesting that the playmaker could recover in time for this summer's tournament.
It is understood that France manager Laurent Blanc will continue to monitor Diaby's fitness.
