The Gunners' French midfielder is set for spell on the sidelines with injury...
"The main question mark is about Diaby," Gunners boss Arsene Wenger told Arsenal TV Online.
"He is certainly short [for Saturday] and we will assess him on Friday morning.
"I rushed Diaby back a little bit because he had only one or two days with the team training and I felt on the day we needed him in central midfield against Roma. I rushed him a bit and maybe it was a bit early for him. But the good side of it is that there doesn't seem to be any major damage so, if not for Saturday, he will be available for Tuesday [against West Brom]."
"Everybody else looks alright to be available for Saturday. William Gallas had a kick on his ankle but he looks not to have a problem. But we have nobody else coming back."
Arsenal's treatment room is currently a pretty busy place, with Cesc Fabregas (knee), Theo Walcott (shoulder), Tomas Rosicky (hamstring tendon), Mikael Silvestre (calf), Eduardo and Emmanuel Adebayor (both hamstring) all stuck there currently. Of that fairly illustrious list of names, Wenger thinks that his English attacking dynamo and his Croatian striker will be first to return to action.
"Who will return first? Walcott, Eduardo and, just behind them, Adebayor," added the Frenchman
"It's difficult because we have to integrate Walcott into full training on Monday and we have to see how he responds with his shoulder. For him it is no injury problem, it is just getting used to playing again.
"Eduardo could be available for Burnley and Adebayor, just behind that, for Roma. It is too early to say."
