The 25-year-old has been out of action since pre-season after undergoing ankle surgery. The Frenchman now faces a further three weeks out with a hamstring problem.
“You won’t see him [Diaby] for a while, the next three weeks,” said Arsenal boss Arsene Wenger. “He will not play for France either.
“I am worried but I was more worried three months ago. His ankle was not good but the surgery went very well then.
“Now his balance has changed so he has to adjust his muscular strength. He has had two small muscular concerns and if he can get rid of them in the next two to three weeks he will be ready.
“It’s a good time to get him right as we have a two-week break after Saturday.”
