Tomas Rosicky has suffered another set-back in his bid to make a long awaited return to first team action.
The Czech Republic international has not played for the Gunners since January last year due to a problem with his hamstring tendon.
After initially struggling to diagnose the injury it was then thought that the midfielder would be back in time for the start of this season.
Since then several comebacks have been pencilled in only for the 28-year-old's hamstring to flare up as soon as the training regime was stepped up.
But a return to action in the next few weeks was thought to be a real possibility, with talk of a reserve game mooted.
But all of that has now been quashed with the former Dortmund playmaker facing at least another two weeks on the sidelines.
"Tomas has had a little set-back of one week so he will be out for two weeks again," manager Arsene Wenger told the club's official website.
"We have to be more patient than in the start. I told you two weeks ago that he would be back in full training but he will not.
"He'll be back in full training in two weeks time now."
